Installation
2.8 Connection of "Media Contacts 9" standard auxiliary circuits (figure 16)
Connection of auxiliary circuits on the remote relay board
The standard auxiliary circuits of the rectifier-inverter and Static Switch Cubicles are connected to the remote relay board by
4 connectors (see the location of this board in the figures of the previous section).
– recommended cable cross-section: 1 mm
2
(use a shielded cable to connect the battery cell);
– the male connectors that fit the female connectors on the board (XR1 to XR4) 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.
