Functions
●
The power distribution module provides mains and bypass three-phase, four-
wire input terminals and PE on the UPS rack, provides three-phase, four-wire
output terminals for the whole system, and provides battery string input
terminals.
●
By using the maintenance bypass switch, the power module and bypass
module inside the cabinet can be maintained without disconnecting power
supply.
●
You can short-circuit the mains and bypass input terminals using copper bars,
so that two mains inputs merge into one mains input.
