stranded.
NOTE
Cable ferrules to DIN 46228 standard must be fitted to any stranded cable or
screen wiring that is being used.
Ferrules of length 6mm are recommended for the system wiring terminal blocks.
4.4 Identification and tagging
Each module base is supplied with a clear plastic tag holder that can be fitted with
tagging strips to provide channel identity information.
The tag holder hinges on the UI module side. This may then be lifted up to insert an
identity strip. When a surge protection module is required to be fitted, the tag holder can
be lifted up on its hinge, the surge module plugged into the base module, and finally, the
tag holder is lowered to clip onto the newly inserted surge protection module. Figure 4.3
helps to illustrate the end result.
