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.
