UPS Multi-Module Installation

The basic installation procedure for a parallel system consisting of two or more R90-20KVA modules is
that same as that of a single module. The following provides installation procedures related to a parallel
system.

Cabinet Installation

Connect all R90-20KVA UPS required in the parallel system as shown in the diagram below.

Note:

If installing 5-6 units in parallel, remove the jumper cap J30 on the control inspection board

(MHTBJHR1CU04 in all UPS to be connected in parallel.

If installing 7-10 units in parallel, remove the jumper cap J30/J31 on the control inspection

board (MHTBJHR1CU04 in all UPS to be connected in parallel.

Make sure that each UPS input breaker is in the “OFF” position and there is no output from any UPS
connected. The battery strings can be connected separately or in parallel.

WARNING!

MAKE SURE THE N, A(L1), B(L2), AND C(L3) WIRING IS CORRECT, AND THAT GROUND

IS CONNECTED.
