WARNING: Remove all power sources to the panel before installation. Leave the
external and main power OFF until installation is complete.

1. Screw two 3/4” stand-offs onto the mounting studs of a CHS chassis.
2. Place the module on the CHS chassis. Ensure the tab on the module slides into the slot on the
CHS chassis.
3. Secure the module with two 4-40 screws.

2.2 Mounting a LDM Relay Expander
The LDM-R32 can either be mounted alongside a LDM module or expander in the CHS chassis (see
section 2.1 for CHS mounting), or stacked on top of a LDM module using the standoffs provided (see Figure
