7. Check the power supply circuit. The voltage and
frequency tolerance must match those of the S7830. Do
not connect the S7830 to a power supply circuit that can
have wide line voltage variations. A separate power
supply circuit may be required for the S7830. Add the
required disconnect means and overload protection.
8. Check all wiring circuits (see Fig. 3) before installing the
S7830 on the wiring subbase.
9. Install all electrical connectors.
10. Restore power to the panel.

1. Mount the S7830 vertically (see Fig. 3, 4 and 5) or
horizontally with the knifeblade terminals pointing
downward. When mounted on the Q7800A Wiring
Subbase, the S7830 must be in an electrical enclosure.
2. Select the location in the electrical enclosure. Be sure to
allow clearances for servicing, electrical signal voltage
probes and electrical connections. Allow an optional
three inches (8 cm) minimum on both sides of the
S7830 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 that it does not interfere with the knifeblade
terminals or bifurcated contacts.
4. Mount the S7830 by aligning the four L-shaped corner
guides and knifeblade terminals with the bifurcated con-
tacts on the wiring subbase and securely tightening the
two mounting screws.
