3.05INSTALLATION AND SETUP REQUIREMENTS

A.Metal Oxide Varistors (MOV) on Outputs:

1.Install MOVs across all inductive loads being switched by an output from an Delta controller. This includes all relay coils, solenoid coils (E/Ps), etc. Install the MOV across the coil of the device. Use an MOV rated for the voltage of the coil.

B.Grounding the Shield on Communication Wiring:

1.The shield on communication wiring should be grounded in only one location per building. The connection point for the shield wire on LCX and SCX panels is not grounded. Connect the shield to this terminal on each panel just for consistency. The standard grounding location for each building shall be at the Infilink (see 3.03,C).

2.Tape any exposed shield wiring so that it cannot short-out on the Infilink housing or other source.

C.Splices in Communication Wiring:
