TP-6967 8/1518 Section 1 Installation
1.8.1 Field Connections
The generator set is equipped with a field-connection
terminal block located below the fuel inlet. Leads have
been factory-installed from the junction box to the
terminal block for easy field wiring. Refer to the decal
near the terminal block for connections. Also see
Section 2, Wiring Diagrams.
Refer to the decal below the terminal block and the
transfer switch specifications for the cable size range for
each connection. Route leads through flexible conduit.
Use separate conduit for AC wiring and low-voltage
engine start leads. Ensure that the leads and conduit do
not interfere with the operation of the generator set or
obstruct the service areas.
Field Connections to the Terminal Block
1. Remove the cover from the electrical connection
access area. See Figure 1-13.
2. Drill holes for conduit fittings:
a. See Figure 1-13 for the electrical inlet location.
Remove the cover from the electrical inlet area.
b. Drill holes in the cover for the conduit fittings
and replace the cover. Use separate conduit
for AC wiring and low-voltage engine start
leads.
c. Feed the cables through the openings.

3. See Figure 1-14. Connect the leads from the
transfer switch emergency source lugs to the L1
and L2 connections on the generator set terminal
block.
4. Connect the neutral (L0) and ground (GRD) leads
from the ATS and the main panel to the
corresponding connection points on the terminal
block. See Section 1.8.3, Grounding.
5. Connect 120 VAC utility power to the terminals
marked Utility Power. Power to this circuit must be
backed-up by the generator set. See Section 1.5
for more information about the utility power
requirement.
6. Connect the engine start leads from the automatic
transfer switch or remote start switch to terminals 3
and 4 on the terminal block. See Section 1.8.2.
7. Replace the cover over the electrical connection
access area. See Figure 1-13.
