Installation
2.11 Connection of "Media Contacts 15" additional auxiliary circuits
(figure 22)
ACPZ board of the Static Switch Cubicle
The additional auxiliary circuits of the rectifier-inverter and Static Switch Cubicles are connected to additional remote relay
board by means of the 4 connectors (see location of this board in the figures of the "connection of power circuits" section).
– recommended cable cross-section: 1 mm
2
;
– the male connectors that fit the female connectors on the board (XR5 to XR9) are supplied;
– the contacts are volt-free and are shown in the diagram under the following conditions: UPS on, contact at rest;
– contact breaking capacity: 250 V, 5 A.
Note:
In a parallel-connected UPS installation the "load" and "mains 2" signals are provided by the Static Switch Cubicle.
