Installation 2.4.6 Battery Temperature Sensor Installation and Wiring The Battery Temperature Sensor (shown in fi gure 2-7) provides the inverter with precise battery temperature information to automatically adjust the ABSORB and FLOAT charge voltage setpoints This allows the batteries to be correctly charged under extreme temperature changes. If the temperature sensor is NOT installed and if the batteries are subjected to large temperature changes, the battery life may be shortened. - Page 25 Installation 2.4.7 Wiring the Inverter to the Battery Bank CAUTION: Inverter is NOT reverse polarity protected, if this happens the inverter will be damaged and will not be covered under warranty. Before connecting the DC wires from the batteries to the inverter, verify the correct battery voltage and polarity using a voltmeter.

Although this inverter/charger has two electrical systems, each electrical system must be properly grounded and connected to a common “earth”... -
Page 37: Figure 2-17, Multiple Connections To Dc Ground Rod (Method 1)
Installation 2.6.1 Sizing the Grounding Electrode Conductors AC Side - The size of the AC Grounding Electrode Conductor (GEC –AC) depends on the size of the largest ungrounded conductor feeding the AC load center. One #8 AWG (8.4 mm ) copper conductor will serve as an AC Grounding Electrode Conductor (GEC –AC) for AC power conductors smaller than and including #2 AWG (33.6 mm ) copper. -

In this method - since there are multiple connections to the DC Grounding Electrode (GEC –... -
Page 39: Table 2-5, Equipment Grounding Conductor Sizing
2.6.2 System Bonding Jumper The MS Series inverter does not include an internal bond between the Grounded Conductor (AC neutral/DC negative) and the equipment grounding terminals. This bond [System Bonding Jumper (SBJ)] is usually done in the main distribution panel for each electrical system. - Page 40 (shown in fi gure 2-20). The DC ground terminal on the MS Series must also be connected to the boats safety ground bus. This ensures that both the inverters AC and DC ground terminals are connected to the boats safety ground bus as a safety measure to provide protection against faults and provide a path for AC fault currents while the boat is connected to shore power.

2.6.6 Disabling the Neutral-to-Ground Connection All MS Series Inverter/Chargers have the automatic neutral-to-ground switching feature. In some installations/jurisdictions, this feature must be disabled. If you are not sure whether you must disable this feature, check your local code requirements. The following steps will guide you in disabling the neutral-to-ground switching feature in the MS Series inverter/charger. -
Page 43: Inverter Notifi Cation Requirements
Installation Inverter Notifi cation Requirements When an inverter is installed in a building, facility or structure, the NEC (National Electrical Code) requires a label or plaque to be provided. This label/plaque is required to be easily visible and provide information that informs personnel on the location of all electrical system disconnects. This is to ensure all power to a building is quickly located and shutdown in an emergency. -
Page 44: Functional Test
Installation Functional Test After all electrical connections to the inverter, batteries, AC source, and sub-panel have been completed; follow these steps to test the installation and the inverter operation. CAUTION: Use a multimeter to verify the correct DC voltage for your particular inverter model (i.e., 24-volt battery bank for a 24-volt inverter) and ensure the polarity of the battery voltage is correct (battery positive connected to inverter positive terminal and negative battery connected to inverter negative terminal). -

Page 46: Standby Mode
Operation Standby Mode The MS Series features an automatic transfer relay and an internal battery charger when operating in the Standby Mode. The Standby Mode begins whenever AC Power (Utility or Generator) is connected to the inverter’s AC input. Once the AC voltage and frequency of the incoming AC power is within the AC input limits, an automatic AC transfer relay is activated. -

24.2 VDC on 24-volt models) or lower, the unit will begin another Bulk charge. * These settings in the MS Series are changeable and leave the factory with default values (see Table 3-2, Inverter/Charger Default Values). These default values are adequate for most installations, however, if you determine that some of the values need to be changed for your particular system, the ME-RC50 remote control may be purchased to adjust these settings. -
Page 48: Transfer Time
The transfer from Standby mode to Inverter mode occurs in approximately 16 milliseconds. While the MS Series is not designed as a computer UPS system, this transfer time is usually fast enough to hold them up. However, the VAC dropout setting has an effect on the ability of the loads to transfer without resetting. -
Page 49: Protection Circuitry Operation
Operation Protection Circuitry Operation The inverter is protected against fault conditions and in normal usage it will be rare to see any. However, if a condition occurs that is outside the inverter’s normal operating parameters, then it will shut down and attempt to protect itself, the battery bank, and your AC loads. If there is a condition that causes the inverter to shutdown, it may be one of the following conditions [also refer to the Troubleshooting section (Section 4.3) to help diagnose and clear the fault condition]. -
Page 50: Inverter Startup
Operation Inverter Startup ON/OFF Switch - The inverter can be turned on and off by lightly pressing and releasing the Power ON/OFF switch on the front of the inverter (refer to fi gure 3-5). When the inverter is fi rst connected to the batteries, or when its automatic protection circuit has turned the inverter off, the ON/OFF switch will need to be pressed to start the unit (or reset per section 4.4). -
Page 51: Factory Default Values
Operation Factory Default Values Your MS Series inverter/charger uses default values for the adjustable settings (shown in Table 3-2) that are adequate for most installations. If some of your operating parameters need to be changed from the default values, the optional ME-RC remote control can be used to make those changes. -
