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 cubicles when the batteries of these cubicles are located in the same room at the same ambient temperature.
