    All Legend Series II inverters include extensive protection circuitry, Search Sense Mode, Impulse Phase Correction, true RMS voltage regulation, crystal-controlled timing, three-stage battery charging, and an internal AC transfer relay. The inverter is protected from high-battery voltage, low-battery voltage, over-heating, and over- current conditions.

  • Page 16: Over Current Cut Out

    Over Current Cut Out Series II inverter/chargers are protected from over-current conditions. When the load being run demands more current than the inverter can safely supply, the inverter will momentarily shutdown, turn off if it encounters an over-current condition for approximately 20 seconds (a prolonged short- circuit) or if the AC output is connected to another AC power source (shorepower or generator).

  • Page 17: Shore Power Amps Monitoring

    Shore Power Amps Monitoring Series II models monitor the current drawn by the built-in charger and any AC loads. These current requirements may exceed the amperage rating of the shore power circuit breaker. To prevent unnecessary tripping of this circuit breaker, the inverter limits the current draw to a maximum between five and 30 amps, set by using the RC7 remote control.

  • Page 18: Impulse Phase Correction

    Example B: If the threshold is set to detect a 30-watt load and a 40-watt fluorescent light is turned on, the inverter will not detect the light. The light presents a smaller load than 30 watts until the gas in the fluorescent tube ionizes.

  • Page 19: Crystal Controlled Time Base

    Proper frequency regulation is assured with the use of a crystal. Battery voltage and power have no effect on the inverter’s operating frequency. The Stand-by feature includes an internal battery charger and automatic transfer relay. This allows the unit to operate as a battery charger or an inverter (but not at the same time).

    Power Output Ambient Temperature in Celsius Figure 1, Power Output Versus Temperature Figure 1, Power Output Versus Temperature is for the L3012. It outlines the ambient temperature needed in order for the inverter to perform to its published specifications. The chart shows the output capabilities of the inverter, which is dependent on the ambient temperature in the enclosure where the inverter is located.

  • Page 33: Safety Instructions

    Safety Instructions The inverter’s maximum peak current requirements and the charger’s output current capabilities are high. If battery cables are too small and/or connections are loose, efficiency and maximum output power are degraded. Small cables or loose connections can also cause dangerous overheating of the wire and/or terminals.

  • Page 34: Figure 2, Battery To Inverter Cable Connection

    Cables must have crimped and/or soldered copper compression lugs unless aluminum mechanical lugs are used. We suggest using high quality UL listed Trace Engineering battery cables. These cables are available in a specific assortment of sizes from 1 ½ to 10 feet, and in 2/0 or 4/0 AWG. They are color-coded and have pressure crimped, sealed ring terminals.

  • Page 35: Ground Cable Connection

    Copper Compression Lugs: Commonly available at hardware, welding, and auto parts retailers, compression lugs must be crimped onto each cable using an appropriate crimping tool.

  • Page 39: Ac Wiring

    The National Electrical Code (NEC) defines the standards for AC installation wiring in vehicle applications, but there are still many installation variables; most are determined by the level of automatic switching desired and the amount of external AC power to be switched. A qualified electrician should do the installation.

  • Page 40: Figure 5, Ac Wiring Diagram

    The following steps are a basic guideline for installation and connection of the AC wiring into and out of the inverter. 1. Disconnect the inverter from the battery bank (if already connected), by either removing the DC side fuse, or opening the DC disconnect. Then remove the AC wiring compartment cover from the front of the inverter by removing the two screws at the bottom of the cover.

  • Page 43: Neutral-To-Ground Switching

    Neutral-to-Ground Switching All of the Legend Series units employ neutral to ground switching as required by the NEC (National Electric Code). The purpose for this requirement is to ensure that the neutral conductor in a three- wire system is "bonded" or connected to ground at only one point. This prevents a voltage difference from developing between the vehicle’s neutral and the AC source’s neutral, which may cause an electric shock.

  • Page 44: Figure 8, Neutral-To-Ground Switching With External Ac

    For this system to work, the AC output neutral of the inverter must be isolated from the ground of the system (usually the green wire). When in the inverter mode, the neutral ground switching relay will automatically connect (bond) the output neutral to ground, and when in charger/pass-through mode, the ground and neutrals will be bonded to one another at the AC source (generator or shore power).

  • Page 45: Disabling Neutral Ground Switching

    If no neutral to ground switching were employed in an inverter there would be one neutral tied to the AC sub-panel and the other neutral to the vehicle or chassis ground. The two different ground points would now form a current carrying conductor with the vehicle chassis acting as the “wire” between the two different ground points.
  • Page 46 5. Do not cut the green wire that goes from the connector block to the chassis. 6. Replace the AC terminal block cover and reconnect the battery(s) and the AC sources. Once the AC and DC wiring have been installed and connected, take a moment to go back over all connections and make sure they are secure and in the proper terminal(s).
  • Page 47 4. Disconnect shore power. Take away the shore power by turning the shore power breaker off, or unplugging the shore power. The inverter should transfer to inverter mode immediately. This will be indicated by a clicking sound as the internal transfer relays change position. The inverter will begin to “buzz”...

  • Page 49: Operation

    This section of the manual is included to help you better understand the factors involved with battery charging, care, and maintenance, by discussing the physical make-up and characteristics of chemical storage batteries. This is not intended to be an exhaustive discussion of battery types, but simply a guideline.

  • Page 50: Types

    There are two principal types of batteries: starting and deep-cycle. There are several different types of battery chemistries including liquid lead-acid, nickel-iron (NiFe), nickel-cadmium (NiCad), alkaline, and gel-cell. Batteries are either sealed or vented. Starting Batteries Starting batteries are designed for high cranking power, but not deep cycling. Do not use them with your inverter.

    require routine maintenance), long life (800 cycles claimed) and low self-discharge. The disadvantage is high initial cost and the possibility of damage from overcharging. While there are many manufacturers of quality non-sealed batteries, there are only a few manufacturers of suitable gel-cells. Don’t confuse sealed batteries with maintenance free batteries. The latter is typically a standard liquid electrolyte type battery without caps for adding water, and when the electrolyte gets low, you replace the battery.

  • Page 55: Monthly Maintenance

    At a minimum, check the level of the electrolyte in each battery cell once a month (for non-sealed batteries). It should be above the top of the plates, but not completely full. Most batteries have a plastic cup that, when full, just touches the electrolyte. Don’t overfill the batteries or the electrolyte will spill out of the batteries when they are being charged.

    turn the DC disconnect switches to the ‘Off’ position. Using the appropriate tool, remove the Negative battery cable first and install it last. Use a toothbrush (or other soft bristle brush) and baking soda to remove any stubborn residue. Sprinkle the baking soda directly on the area and scrub with a wet toothbrush, adding water as required, then rinse.

  • Page 58: Parallel Connection

    Parallel Connection Batteries are connected in parallel when all the positive terminals of a group of batteries are connected and then, separately, all the negative terminals are connected. In a parallel configuration, the battery bank have the same voltage as a single battery, but an amp/hour rating equal to the sum of the individual batteries.

  • Page 59: Series - Parallel Connection

    Series – Parallel Connection When pairs of batteries are connected in series and parallel, the result is an increase in both the voltage and the capacity of the total battery bank. This creates a larger, higher-voltage battery bank out of several smaller, lower-voltage batteries – a common practice in battery/inverter systems. In the illustration, each battery in the bank has 100 amp-hours capacity at 6 VDC.

  • Page 60: Three-Stage Battery Charger

    The Legend Series II inverter/charger has a fully functional three-stage battery charger. Anytime an acceptable (within frequency and voltage parameters) AC source is presented to the unit, it will charge the batteries connected to it. The On/Off switch on the inverter does not control the charger portion of the unit.
  • Page 61 Bulk Voltage - This is the maximum voltage the batteries will reach during a normal charging cycle. The normal range is 2.35 to 2.42 volts per cell. For a 12 VDC battery (6 cells) this is 14.1 to 14.5 volts. Liquid electrolyte batteries are charged to a higher voltage, while gel-cell batteries have a lower voltage.

  • Page 62: Table 5, Bulk And Float Setpoints

    Table 5, Bulk and Float Setpoints Typical BULK and FLOAT Setpoints for Common Battery Types (12V System) Battery Type Bulk Volts Float Volts 14.1 volts 13.5 volts Gelled Lead-Acid (sealed) 14.5 volts 13.4 volts Liquid Lead-Acid (non-sealed) The maximum charge rate of the battery charger is dependent upon the peak AC voltage available. Since the battery charger uses only the top portion of the input sine wave, small variations in peak voltage results in large variations in the amount of energy to the charger.

  • Page 63: Charging Profile Generator Requirements Theory Of Inverter Operation

    The Trace Legend Series II inverter/chargers utilize a low frequency power transformer-based design. This design takes low voltage direct current from a DC source (usually a battery bank) and produces higher voltage power. High efficiency is achieved by utilizing top quality field effect transistor switches (FET’s) in an “H-bridge”...

  • Page 64: R Egulation

    An advantage of a modified square wave compared to a square wave is the ability to regulate Root Mean Square (RMS) voltage by means of varying the pulse width, and off time periods. The pulse width variation method of regulation is referred to as pulse width modulation or PWM. RMS regulation should keep the area inside the waveform equal at all times.

  • Page 65: R Esistive L Oads

    AC loads on the inverter differ in the way they perform. There are different types of loads: resistive loads, inductive loads, and problem loads . These are the loads that the inverter finds the simplest and most efficient to drive. Voltage and current are in phase, or, in this case, in step with one another.
  • Page 66 Trace Engineering inverters can drive nearly every type of load. However, there are special situations in which inverters may behave differently than public power. Trace has provided the following knowledge as guidelines only. Trace does not guarantee that your experiences with any particular product will duplicate ours whether good or bad.
  • Page 67 Dimmer switches- Most dimmer switches lose their ability to dim the lights and operate either fully on or off. Trace has had reports of success with the 600 watt, 120vAC Leviton slide dimmer switches (Leviton P/N-6621). These have been reported as working reliably every time with a modified square wave output inverter.

  • Page 69: Options

    Options available for the Legend Series II inverter/charger include a choice of remote controls, and a battery temperature control. The optional RC6 remote control unit duplicates the Power On/Off Switch on the Legend Series II inverter/charger. It connects directly to the port labeled Remote Control on the front of the inverter, using standard phone cable and jacks.

    four lights will blink when an error condition occurs. The Bulk Charge or Float Charge lights will light to indicate the inverter is in either the bulk or float stage of the charging process. In order for the inverter to recognize the RC6, it must be powered up with the RC6 already plugged in.
  • Page 71 When the RC7 is connected to the inverter, the inverter’s status LED still operates normally. Installation and operating instructions are included with the RC7. An optional plug-in external battery-temperature sensor (BTS) automatically fine-tunes the charging process of the charger. When the temperature sensor is installed, the inverter/charger adjusts the BULK and FLOAT charge voltage .
