Select Mounting RM7898 Relay
Module
1. Mount the RM7898 vertically on the Q7800 Subbase, or
mount horizontally with the knife blade terminals
pointing down. (For mounting on the Q7800A, mount
the RM7898 in an electrical enclosure.)
2. When mounting in an electrical enclosure, provide
adequate clearance for service, installation and removal
of the RM7898, KDM, flame amplifier, flame amplifier
signal voltage probes, electrical signal voltage probes,
and electrical connections.
a. Allow an additional 2 in. (51 mm) below the RM7898
for the flame amplifier mounting.
b. Allow an optional 3 in. (76 mm) minimum to both
sides of the RM7898 for electrical signal voltage
probes.
3. Make sure no subbase wiring is projecting beyond the
terminal blocks. Tuck in wiring against the back of the
subbase so it does not interfere with the knife blade
terminals or bifurcated contacts.
IMPORTANT
Install the RM7898 with a plug-in motion rather than
a hinge action.
4. Mount the RM7898 by aligning the four L-shaped corner
guides and knife blade terminals with the bifurcated
contacts on the wiring subbase and securely tightening
the two screws without deforming the plastic.
