Final Wiring Check
1. Check the power supply circuit. The voltage and
frequency tolerance must match those of the
RM7895A,B,C,D/EC7895A,C; RM7896A,B,C,D. A
separate power supply circuit can be required for the
RM7895A,B,C,D/EC7895A,C; RM7896A,B,C,D. Add
the required disconnect means and overload protection.
2. Check all wiring circuits and complete Static Checkout
in Table 6 before installing the RM7895A,B,C,D/
EC7895A,C; RM7896A,B,C,D on the subbase.
3. Install all electrical connectors.
4. Restore power to the panel.
