Installation Auxiliary Relay Module (ARM-4): Product-Specific Details
• Install two (2) mounting stand-offs onto the studs of the chassis, at the selected location, as
shown in Figure 3.8 on page 38 and Figure 3.25. Tighten securely.
• Install three (3) support stand-offs, with screws, onto the PC board in the locations shown in
Figure 3.8 or in the two right-hand positions on the first row. Tighten securely.
• Position module over the stand-offs on the chassis; fasten the module to the chassis with the
two (2) retaining screws. Tighten securely.
• Connect one end of the Cable (P/N 71092) to plug P1 on the ARM-4.
Note: The other end of the cable is connected to jumper JP5 on the CRM-4RK or CRE-4.
• Connect all available external wiring at this time. Refer to Section 3.13.3 “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 through different
knockouts, conduits, or both.
The table contains contact ratings for relays K1-K4 on the ARM-4 module:
