Vertiv I Liebert ITA2 30kVA I Manual
According to user's requirements, the I/O cable connections are divided into two types: 3-in
3-out, common input configuration (factory default), 3-in 3-out, split-bypass configuration.

The I/O cable connection procedures of the self-distribution for the two types are as follows:
3-in 3-out, common input configuration (factory default)
1. Three shorting copper bars (1#) are connected between the input & bypass terminals mA
and bA, mB and bB, and mC and bC respectively before delivery.
2. Connect the mains input live wires (L1, L2, L3) to the three shorting copper bars 1# and
connect input N line and input PE line respectively to the I/O terminal block (N and PE
terminals) of the UPS.
3. Connect the standard output live wires (phase-A, phase-B and phase-C) respectively to
the output terminals sA, sB and sC. Connect the output N line and output PE line
respectively to the output terminals N and PE. As shown in Figure 2-1

.
4. As shown in Figure 2-14, lead the battery positive cable, battery N cable and battery
negative cable through the cable hole of the junction box, then respectively connect them to
BAT+, BAT N, BAT- and PE, then fasten the fixing screws.
