Field Connections

Customer connection points are located as shown in
Figure 3-3. Open the enclosure roof and locate the
cover panel over the circuit breaker. Remove the cover
panel to access the power and load connections.
Remove the air intake end panel for access to the
engine start and communication connections to the
transfer switch. See Section 3.3 for more details about
the transfer switch connections.
Route AC leads through flexible conduit. Ensure that
the leads and conduit do not interfere with the operation
of the generator set or obstruct the service areas. Route
low-voltage communication leads through separate
conduit.
Procedure
1. Punch or drill holes for the conduit fittings. See
Figure 3-2 for the recommended electrical inlet
locations. Feed the cables through the openings.
2. Connect the leads from the transfer switch
emergency source lugs to the L1, L2, and L3
connections on the load circuit breaker as
applicable for single or three-phase applications.
See Figure 3-3.
3. Connect the neutral (L0) and ground (GRD) leads
from the ATS and the main panel to the
corresponding connection points near the circuit
breaker. See Figure 3-3. Also see Section 3.1.2,
Grounding.
4. Connect AC power source leads to the terminal
block connections labeled HOT, NEUTRAL and
GROUND. Connect to a circuit that is fed by the
load side of the transfer switch to ensure that
battery charging power is available at all times.
See Section 3.1.5 for more information about the
AC power requirement.
Note: To maintain the charge on the engine
starting battery, AC power must be
connected to a circuit that is fed by the load
side of the transfer switch so that it is backed
up by the generator.
5. Connect a model RXT, RDT, or other transfer
switch to the terminal block in the air intake area.
See the Figure 3-3 and Section 3.3.2.
