Mounting RM7800L/40L, EC7840L
Relay Module (Fig. 9)
1. Mount the RM7800L/40L, EC7840L vertically on the
Q7800 Subbase, or mount horizontally with the
knifeblade terminals pointing downward. When
mounted on the Q7800A, the RM7800L/40L, EC7840L
must be in an electrical enclosure.
2. When mounting in an electrical enclosure, provide
adequate clearance for servicing, installation and
removal of the RM7800L/40L, EC7840L, Keyboard
Display Module, flame amplifier, flame amplifier signal
voltage probes, electrical signal voltage probes, and
electrical connections.

a. Allow an additional two inches below the
RM7800L/40L, EC7840L for the flame amplifier
mounting.
b. Allow an optional three-inch minimum to both sides
of the RM7800L/40L, EC7840L 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 knifeblade
terminals or bifurcated contacts.
IMPORTANT
The RM7800L/40L, EC7840L must be installed with
a plug-in motion rather than a hinge action.
4. Mount the RM7800L/40L, EC7840L by aligning the four
L-shaped corner guides and knifeblade terminals with
the bifurcated contacts on the wiring subbase and
securely tighten the two screws without deforming the
plastic.
