Fig. 22

Connection of "Media Contacts 15" additional auxiliary circuits (option) (figure 22)

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 mm2;

◗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;

ACPZ board of the Static Switch Cubicle

◗contact breaking capacity: 250V, 5A.

Note:

In a parallel-connected UPS installation

the "load" and "mains 2" signals are

provided by the Static Switch Cubicle.
