Final Wiring Check
1. Check the power supply circuit. The voltage and fre-
quency tolerance must match those of the
RM7838A. A separate power supply circuit can be
required for the RM7838A. Add the required discon-
nect means and overload protection.
2. Check all wiring circuits and complete Static Check-
out in Table 7 before installing the RM7838A on the
subbase.
3. Install all electrical connectors.
4. Restore panel power.
STATIC CHECKOUT
After checking all wiring, perform this checkout before
installing the RM7838A on the subbase. These tests verify
that the Q7800 Wiring Subbase is wired correctly and that
the external controllers, limits, interlocks, actuators,
valves, transformers, motors and other devices are
operating properly.
