XP-6341 6/10 9 Section 1 General
set specification sheet for fuel supply pressure
requirements.
Primary gas regulator. The primary regulator reduces
the high pressure from a tank or transmission line to the
lower pressure required by the secondary regulator on
the engine.
The fuel supplier provides the primary
regulator. The fuel supplier is also responsible for
providing sufficient gas pressure to operate the primary
regulator.
Secondary gas regulator. The secondary regulator is
factory-installed on the generator set engine and
controls the inlet pressure to the engine.
Integrated electronic secondary pressure
regulators. Models with generator set serial numbers
above 2272938 use an electronic pressure regulator.
See Section 2.2.7.
Note: The Integrated Electronic Pressure Regulator
(IEPR) and air/fuel mixer are specially calibrated
emission-control devices. Do not adjust the IEPR
or the air/fuel mixer.
1.6 Oil Makeup Kit
The oil makeup kit includes an oil level gauge and a
2-quart reservoir to provide additional oil for the engine.
Check the oil level in the gauge and reservoir, and follow
the instructions provided with the kit to add oil, if
necessary.
Note: The oil reservoir bottle looks similar to the coolant
bottle. Be sure to add oil only to the oil reservoir.
1.7 Electrical System
Before installing the generator set, provide for electrical
connections through conduit to the transfer switch and
other accessories for the generator set. Route DC leads
in separate conduit from AC conductors.
Carefully
install the selected generator set accessories. Route
wiring to the generator set through flexible connections.
Comply with all applicable codes when installing a wiring
system.
1.7.1 Line Circuit Breakers
AC circuit protection. All AC circuits must include
circuit breaker or fuse protection. If the generator set is
not equipped with a factory-installed circuit breaker,
select a circuit breaker for up to 125% of the rated
generator set output current. The circuit breaker must
open all ungrounded connectors. The circuit breaker or
fuse must be mounted within 7.6 m (25 ft.) of the
alternator output terminals.
1.7.2 Electrical Connections
Several electrical connections must be made between
the generator set and other components of the system
for proper operation. Most field-installed accessory kits
include installation instructions. Comply with applicable
national and local codes when installing a wiring system.
Size the wire according to the length of run and 115% of
the circuit current (amperage) as directed by the
National Electrical Code
r
(NEC) in ANSI/NFPA 70.
For Canadian installations, refer to the Canadian
Electrical Code (CEC).
1.7.3 Load Lead Connections
Feed load leads to the generator set junction box
through the nonservice side of the box. See Figure 1-1.
Route DC leads in separate conduit from AC
conductors.
