Adhere to the following guidelines when wiring base panel relay modules. These guidelines and
specifications apply only to the standard, on-board relays. Information regarding the
specifications and wiring of the optional auxiliary relays is located in document 431305.
All wiring must be 18 AWG (min.) to 12 AWG (max.)
Conductors must test free of all grounds.
Relay circuits are rated for 2A (max.) at 30 VDC (max.), pilot duty (0.35 power factor).
Circuit is not supervised.
When setting jumpers to select Normally Open or Normally Closed contacts, position jumpers
as follows:
Normally Closed, position jumper to the left.
Normally Open, position jumper to the right
All relays are single pole, double throw.
If power source is not power limited to the requirements of UL864, wiring is to be segregated
to the non-power limited spaces of the cabinet. See “Wiring AC Power” later in this chapter
for the location of the non-power limited cabinet area.
