EMIU 1500W Mini Inverter

EMIU 1500W Mini Inverter

INTERRUPTIBLE EMERGENCY LIGHTING

UNIT INVERTER INSTRUCTION MANUAL

THIS UNIT CONTAINS A 

RECHARGEABLE VALVE-REGULATED  

LEAD ACID BATTERY. PLEASE 

RECYCLE OR DISPOSE OF 

PROPERLY.

IMPORTANT SAFEGUARDS

When using electrical equipment, basic safety precautions should always be followed, including the following:

READ THIS MANUAL AND FOLLOW  ALL SAFETY INSTRUCTIONS 
THOROUGHLY BEFORE OPERATING THE EMIU INVERTER SYSTEM

SAVE THESE INSTRUCTIONS

1. Install in accordance with the National Electrical Code and local regulations.
2. The 

EMIU

 contains potentially hazardous  voltages. Installation, maintenance  and service work should be performed by qualified 

and trained personnel.

3. Units to be installed only as per configuration described in this instruction manual.
4.

Electricians and end-users need to ensure product system compatibility before final installation.

5. The AC voltage rating of this equipment is specified on the product label. Do not connect the 

EMIU

 equipment to any other voltage.

6. All unused wires must be capped to prevent shorting. 
7. The 

EMIU

 should be mounted securely and in locations and at heights where it will not be readily subjected to tampering by 

unauthorized personnel.

8. The use of accessory equipment and replacement parts not recommended by manufacturer may cause an unsafe condition and will 

void the warranty.

9. Do not mount near gas or electric heaters.
10. Do not let power supply cords touch hot surfaces.
11.

D

o not use this equipment for other than its intended use.

12. DO NOT USE OUTDOORS. 

13.  The 

EMIU

 uses sealed valve regulated lead acid batteries. Batteries can be punctured if not handled properly, therefore use caution 

when servicing batteries.  In the event battery acid comes in contact with eyes or skin, flush with fresh water and consult a physician 
immediately.       

NOTE: At 120Vac, unit is rated at power factor 0.8. For loads having a power factor below 0.8, unit capacity needs to be derated.

      At 277Vac, unit is rated at unity power factor. For loads having a power factor below 1, unit capacity needs to be derated.

All ABB inverter products receive 100% quality inspection before shipment to ensure proper and satisfactory operation.

When operated under normal conditions, ABB inverter products will provide years of dependable service.
