2.3.5 Control Module
2.3.5.1 Overview
In a standard configuration, the control module consists of two ECMs, one dry
contact card, and one monitoring interface card (from left to right). The four cards
are hot swappable. One subrack is reserved above the dry contact card. A
backfeed protection card or dry contact extended card can be inserted into this
subrack.

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.
