EC7823A;RM7823A 7800 SERIES RELAY MODULES
Mounting EC/RM7823A Relay Module
1. Mount the EC/RM7823A on the Q7800 Subbase
vertically, or mount horizontally with the knife blade
terminals pointing down. When mounted on the Q7800A
Wiring Subbase, the EC/RM7823A must be in an
2. When mounting in an electrical enclosure, provide
adequate clearance for servicing, installation and
removal of the EC/RM7823A, keyboard display module,
flame amplifier, flame amplifier signal voltage probes,
electrical signal voltage probes, and electrical
a. Allow an additional two inches below the
EC/RM7823A for the flame amplifier mounting.
b. Allow an optional three inches minimum to both
sides of the EC/RM7823A for electrical signal

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.
The EC/RM7823A must be installed with a plug-in
motion rather than a hinge action.
4. Mount the EC/RM7823A 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.
