NSTALLATION
FCM II modules are easily attached to 35mm DIN rails by tilting the top edge toward the panel and catching the
top edge on the rail (see Figure 2.1 below). Then the module is swung back down until the spring loaded metal
foot catches on the bottom edge of the rail (see Figure 2.2 below). The 24 Vdc power and RS-485
communication is connected by s
liding adjacent FCM II’s together until the bus connectors click into place (see
Figure 2.3 below).

EMOVAL
Module removal is the reverse of installation. Power must be removed from the modules. Then, spread the
module to be removed from adjacent modules on either side. Disengage the spring loaded bottom catch by
inserting a ¼” Flat Head screwdriver and sliding the catch away from the rail and tilting the module top toward the
panel. With the bottom edge disconnected, the top foot may by moved off of the rail to free the module. Do not
attempt to open the module’s plastic housing.
