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).
