Auxiliary Relay Wiring
• All wiring must be 18 AWG (minimum) to 12 AWG
(maximum).
• Conductors must test free of all grounds and stray volt-
ages before connection to appliances, devices, and
panel.
• All wiring is unsupervised.
• Contact rating: 30VDC @ 2A (pilot duty, .35 power fac-
tor).
• Each relay is selected for normally-closed or normally-
open operation. Shunt jumper setting selects desired
contact.
• Relay 1 is programmable. Default operation is -- On
Until Reset.
• Relay 2 is a normally energized trouble relay. The
jumper settings shown account for the relay being nor-
mally energized. When the panel is completely powered
“Off”, the trouble relay will be in the “Off Normal”
state.
