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.
