Field Wiring an Auxiliary Relay Module
The figure above shows terminal assignments for ARM-4 module control relays K1-K4, which control
non-power-limited circuits. Power-limited and non-power-limited circuit wiring must remain separated
by at least 0.25 inch (6.35 mm) within the cabinet and exit the cabinet though different knockouts,
conduits, or both. Refer to Section 3.16 “UL Power-limited Wiring Requirements”.
The table contains contact ratings for relays K1-K4 on the ARM-4 module:
