Feed the cable into the Control Panel via a metal IP65 EMC gland supplied, ensuring that the metal 
prongs make a good contact with the exposed cable screen as shown. The gland should be fixed in place 
using a toothed nut to cut through the Control Panel paint. 
The relays should be connected to the Alarm Monitoring System, AMS, to initiate the required response 
when the relay is activated.

At the Control Panel strip the power and communications cables to the required length.  The cables 
should be long enough to reach easily from the gland to the terminal and run tidily around the edge of 
the Control Panel.  Leave approximately 35mm of screen and fold it back over the outer insulation. 
Alternatively, for the power cable remove approximately 1cm of the outer sheath to expose the cable 
screen as shown see Figure 21
