Mounting RM7800L/40G,L,
EC7840L
Relay Module (Fig. 9)
1. Mount the RM7800L/40G,L, EC7840L vertically on
the Q7800 Subbase, or mount horizontally with the
knifeblade terminals pointing downward. When
mounted on the Q7800A, the RM7800L/40G,L,
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/40G,L, 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/40G,L, EC7840L for the flame ampli-
fier mounting.
b. Allow an optional three-inch minimum to both
sides of the RM7800L/40G,L, EC7840L for elec-
trical signal voltage probes.
NOTE: 1xxx series is compatible with any subbase. 2xxx
series requires the 2xxx subbase.
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/40G,L, EC7840L must be installed
with a plug-in motion rather than a hinge action.
4. Mount the RM7800L/40G,L, EC7840L by aligning
the four L-shaped corner guides and knifeblade ter-
minals with the bifurcated contacts on the wiring
subbase and securely tighten the two screws without
deforming the plastic.
