.
Main AC Wiring
NOTE: Main AC wiring must be in accordance with local
jurisdiction and codes.
NOTE: Generator set lugs are rated at 75 °C (167 °F),
copper or aluminum.
1. Strip insulation off wire ends. Do not remove
excessive insulation.
2. See Figure 6-1 . Loosen lugs at neutral (E2), PE
ground (G), and power wire (mains) terminal (E1).
3. Connect ground wire to PE ground lug (G) and
tighten to required specification. See
Table 6-4 .
4. Connect neutral wire to neutral lug (E2). Tighten to
required specification. See
Table 6-4 .
5. Insert power wire into power lug (E1). Tighten to
required specification.
6. Verify factory-installed ground array and alternator
winding junction are correctly tightened to 2.82 Nm
(25
in-lbs ).
NOTE: Tighten all wiring lugs, bus bars, and connection
points to required torque specifications.
Conductors of AC and DC circuits, rated 1000 volts nom-
inal or less, may be permitted to occupy the same equip-
ment, cable, or conduit. All conductors shall have an
insulation rating equal to at least the maximum circuit
voltage applied to any conductor within the equipment,
cable, or conduit. Verify this installation complies with
national and local electrical building codes.
Common Alarm Relay (Option)
Alarms relating to generator and engine performance
appear on the controller and in the Mobile Link Wi-Fi app
(if used). The controller is equipped with a common alarm
relay providing contacts for an optional customer-sup-
plied external alarm indicator.
The common alarm relay is normally open until an alarm
occurs, triggering the relay to close the contacts.
Terminals for the common alarm relay are provided in the
wiring harness near the controller plug (Wires 209 and
210).
Contact rating is for resistive load only:
Battery Requirements
12 volts, Group 26R Wet Cell 540CCA minimum, or
Group 35 AGM 650CCA minimum.
