7.4.4 Parallel Isolator (IA2)

The UPS unit is provided with an output isolator switch (IA2) which, when opened, isolates the corresponding unit from the LOAD. Once IA2 is open, there is no power coming from the inverter. This switch should always be in the “I” (ON) position, except for servicing the UPS when in the maintenance bypass mode. Rotating this switch to the “O” (OFF) position while the inverter is supplying power to the load will dump the critical load. This switch is also provided for future expansion requirements.

WARNING:

Rotating the output isolator switch (IA2) to the “O” (OFF) position when the maintenance bypass switch (IA1) is in the “O” (OFF) position will interrupt power to the critical load.
