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. |
