IMPORTANT SAFEGUARDS
When using electrical equipment, basic safety precautions should always be followed
including the following:
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
A.
Do not use outdoors
B.
Do not mount near gas or electric heaters.

    Normally-On and Normally- Off loads together causes less performance loss than traditional inverters. Since the active PWM regulation scheme produces a very low THD waveform, the E3MINI Series can power up even the most demanding loads driving its output with power factor capabilities ranging from 0.5 leading to 0.5 lagging.

  • Page 4: Receiving And Storage

    2.0 RECEIVING AND STORAGE 2.1 Inspection The E3MINI Series central inverter and batteries are shipped together. Upon arrival, please inspect the contents to ensure that no shipping damage has occurred. This is especially important with the batteries – ensure that there are no cracks or leaks.

    LED status displays. 3.2 Operating Environment Choose a location that is controlled between 20 and 30 °C. E3MINI Series is UL listed between 20°C to 30°C (68°F to 86°F) because of battery discharge performance results. Do not install in a wet or damp location. Do not install in environments that will expose the unit to excessive temperatures like boiler rooms as this will significantly depreciate battery life.

  • Page 6: Knockout Locations

    3.4.3 Knockout Locations Electrical Knock Outs are provided on three surfaces of the E3MINI Series. Ensure all metal conduit is secured and tightened creating a good connection to earth ground. Use an Ohm-Meter to check that continuity between conduit and protective earth ground has been established.

    E3MINI Series electronics module. See section 5.4 for detailed illustrations. DC Voltage of System The systems DC battery voltage for the E3MINI Series is 24VDC for both 125W and 250W models. This voltage is produced by connecting two 12V batteries in series for the 125W model and a series parallel connection for the 250W model.

    7.0 Specifications The E3MINI Series system can be overloaded during normal operation when the dimming option is used. The maximum allowable connected load for both the 125W and 250W model is 375W. The system must be tested to ensure that the connected load power does not exceed the systems rated power (125W/250W) while in the Inverter Mode of operation.

  • Page 14: User Interface

    8.0 USER INTERFACE There are two heads-up LEDs to indicate system status and a recessed test button to initiate the inverter to run in Inverter Mode. Both LED1 and LED2 are bi-color LED’s and will illuminate either solid, blinking, or change between colors for different modes of operation or faults.

  • Page 15: Startup Faults

    BACKFEED (LED1/LED2 – 7 Blinks) Indicates that there is an AC voltage back-feeding the output terminals. This fault means that the E3MINI Series was wired incorrectly between the output terminal and the load(s). 8.6 Charger Faults: While the batteries are being charged, the system will continuously check for faults as part of its diagnostic capabilities.

  • Page 16: Inverter Faults

    Indicates that there is AC voltage already at the output terminals back-feeding into it. This fault means that the E3MINI Series was wired incorrectly between the output terminal and the load. Since this fault was already checked at power up, it is possible that there is a remote transfer device which is back-feeding during Inverter operation.

  • Page 17: System Operation

    9.0 SYSTEM OPERATION 9.1 Startup Mode When the E3MINI Series is first turned on using the System ON/OFF switch, it goes through a sequence of self-tests which ensures proper connections are made and it also checks for faults that may be present. The inverter must qualify several things before advancing to the Battery Charging mode.

  • Page 18: Inverter (Batter Discharge) Mode

    Since the crest factor is very high on the E3MINI Series, loads that have high inrush currents are quickly up and running. This is very beneficial with Switched or Normally- Off loads.

  • Page 19: Warranty

    10.0 WARRANTY There are two separate warranty periods for the E3MINI Series Central Inverter System. The Electronics/Cabinet warranty period is for 3 years from the date of shipment. It is warranted against defects in workmanship and materials under normal and proper use.

  • Page 20: Maintenance And Service

    Please refer to Start up and Shut Down procedures for details. CAUTION – Always assume AC and DC Voltages are present at the E3MINI Series terminals because the inverter is capable of providing output voltage from the batteries when there is no AC input.

  • Page 21: Battery Replacement

    11.2 Battery Replacement E3MINI Series is a UL approved and listed component with exact battery requirements. Failure to replace the batteries with the exact same type will VOID the UL approval. For battery replacement, please call the service number listed in the warranty section so that the unit performs as it was intended.
