3.8.3 Field Wiring an Auxiliary Relay Module
The figure above shows terminal assignments for ARM-4 module control relays K1-K4, which
control nonpower-limited circuits. Power-limited and nonpower-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.
Note: For more information, refer to Section 3.6 “UL Power-limited Wiring Requirements”.
