Installation (cont.)

Connection of the battery "Temperature Monitor" (optional)

Connections

This unit must be connected to connector XR4 of the remote relay board of the rectifier-inverter cubicles (see the location of the remote relay board in the figures of the "power circuit connection" section).

◗ use a shielded cable made up of 2

twisted telephone pairs with a

conductor cross-section of at least

0.1 mm2 and up to 100 m in length;

◗ do not forget to connect the cable

shield to ground pin 7 of connector

XR4;

◗ in the case of a parallel UPS

configuration, the connections between

cubicles may be made by means of a

shielded cable made up of 1 or 2

twisted telephone pairs. In this case,

the total length of all the connecting

cables should not exceed 100 m;

◗ a "Temperature Monitor" can only be

connected to several rectifier-inverter
