EMIU 125/250/400W Mini Inverter

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. DO NOT USE OUTDOORS.
2. All unused wires must be insulated to prevent shorting.

3. Do not mount near gas or electric heaters.
4. Do not let power supply cords touch hot surfaces.
5.

D

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

6. The 

EMIU

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

unauthorized personnel.

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

void the warranty.

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

EMIU

 equipment to any other voltage.

9. Replacement fuse is supplied.
10. 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.

11. Install in accordance with the National Electrical Code and local regulations.
12. The 

EMIU

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

and trained personnel.

13.

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

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

IMPORTANT:

 

Do not exceed the total rating of the Mini Inverter. Unit is rated at maximum Watt and maximum VA, where Max.W 

= Max.VA. Total load (W) must be derated when load power factor (PF) is less than 0.9 (for maximum performance)

.
