9. Check the power supply circuit. The voltage and
frequency tolerance must match those of the 7800
SERIES Relay Module or S7830A. Do not connect the
7800 SERIES Relay Module or S7830A to a power
supply circuit that is subject to line voltage variations,
such as would occur with on-off switching of heavy
loads. A separate power supply circuit may be required
for the 7800 SERIES Relay Module or S7830A. Add the
required disconnect means and overload protection.
10. Check all the wiring circuits and complete a Static
Checkout according to the 7800 SERIES Relay Module
or S7830A Specifications before installing the 7800
SERIES Relay Module or S7830A on the subbase.
11. Install the 7800 SERIES Relay Module or S7830A.
12. Restore power to the panel.
IMPORTANT
Do not run high voltage ignition transformer wires in
the same conduit with the flame detector wiring.
IMPORTANT
Make sure no subbase wiring is projecting beyond
the terminal blocks. Tuck wiring in against the back
of the subbase so it does not interfere with the knife
blade terminals or bifurcated contacts.
CHECKOUT
After installation, perform a complete checkout of the system.
Follow information supplied by equipment manufacturer and
instructions furnished with the 7800 SERIES Relay Module or
S7830A.
SERVICE NOTE:
Voltage checks can be accomplished by using the
electrical access slots on the sides of the Q7800A,B.
Remove the electrical access slot covers on the Q7800B
before making the voltage checks.
WARNING
Electrical Shock Hazard.
Can cause serious injury, death or property
damage.
Always replace the electrical access slot covers on the
