Users Manual

g.Close the input isolation circuit breaker Q1. Verify that the following conditions exist:

The red “load not protected” LED is on

The rectifier/battery charger automatically starts

If either condition is not present, there is a fault. Open Q1 and contact MGE Customer Support Services.

h.Close the battery disconnect circuit breaker QF1. The batteries are now connected to the rectifier/battery charger, and have begun charging.

IMPORTANT:

Because it is standard for the UPS module to be

 

programmed for automatic restart, the inverter will

 

automatically start after the battery disconnect circuit

 

breaker QF1 has been closed.

 

 

i.If the UPS is not programmed for automatic restart, press the “inverter on” pushbutton. The green “load protected” LED will flash for about 3 seconds, indicating that the inverter is starting.

j.The UPS will automatically transfer the load to the UPS inverter output. The green “load protected” LED will turn on and remain on.

NOTE:

If the transfer conditions are not satisfied (bypass AC input

 

sources is out of tolerance) a forced transfer is required.

 

Refer to section 2.12 Forced Transfers.
