2.4 Electrical Installation
Warning – Fuses: To prevent the risk of fire or injury to personnel in the event of
a short-circuit the a.c. mains supply must be fitted with a 6 A slow blow fuse. No
more than five units should be connected to the same supply. If more controllers
are required then each set of five should be connected to a separate, fused mains
supply.
General
The electrical installation is performed in four steps:
1 Configuring the jumper module.
2 Signal connections.
3 Connection of data communications link (if applicable).
4 Connection of the power supply cabling.
Installation of the controller in an electrically noisy environment is described at
the end of this section. The electrical connections can be made either before or
after the cassette is mounted in the panel. The terminal blocks at the rear of the
cassette are shown in Figure 9.
