Section 2 Installation Instructions
Generator sets are shipped with the generator set
neutral attached to the generator set in the junction
box. At installation, the neutral can be grounded at
the generator set or lifted from the ground stud and
isolated if the installation requires an ungrounded
neutral connection at the generator set.
The
generator set will operate properly with the neutral
either bonded to ground or isolated from ground at
the generator set.
Various
regulations
and
site
configurations
including the National Electrical Code (NEC), local
codes, and the type of transfer switch used in the
application determine the grounding of the neutral
at the generator set. NEC 2002 Section 250.20 is
one example that has a very good explanation of
the neutral grounding requirements for generator
sets.
2.2.3
Connect AC and DC Wiring
Note:
Have a licensed electrician make the following
electrical connections.
All connections must
comply with state and local codes.
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. See
Figure 2-1 and refer to the wiring diagrams in Section 4,
Diagrams and Drawings.
Refer to Section 1.7 for additional information about
connecting the electrical system.
Load Lead and Engine Start Connections
1. Install a 120 VAC receptacle for the generator set
battery charger and block heater. Supply power to
the receptacle through a circuit that is powered at
all times, by the utility and by the generator set
during utility power outages.
2. Some codes require the use of a disconnect switch.
Check the code requirements for your location and
install a disconnect switch, if required.
3. Use separate conduit for the power cables and the
low voltage engine start leads. Local codes and the
length of run as well as the transfer switch wire size
requirements will determine the wire size needed
for the AC leads. Route the load leads into the
junction box through the access opening in the
back of the box.
4. Connect the load leads from the line circuit breaker
in the generator set junction box to the transfer
switch emergency power connection points. See
Figure 2-1 and refer to transfer switch installation
manual for ATS connection instructions.
5. Use the remote harness with pigtail connector at
the customer interface connector to connect
engine start leads 3 and 4 to the engine start
terminals on the transfer switch.
Refer to the
transfer
switch
installation
manual
for
ATS
connection instructions.
6. If an auxiliary fault switch is used, connect it to
leads 30 and N at the customer interface
connector.
2.2.4
Install Engine Starting Battery
Explosion.
Can cause severe injury or death.
Relays in the battery charger
cause arcs or sparks.
Locate the battery in a well-ventilated
area. Isolate the battery charger from
explosive fumes.
WARNING
Battery gases.
Explosion can cause severe injury or
death.
Battery gases can cause an explosion. Do not smoke
or permit flames or sparks to occur near a battery at any time,
particularly when it is charging. Do not dispose of a battery in a
fire.
To prevent burns and sparks that could cause an
explosion, avoid touching the battery terminals with tools or
other metal objects. Remove all jewelry before servicing the
equipment. Discharge static electricity from your body before
touching batteries by first touching a grounded metal surface
away from the battery. To avoid sparks, do not disturb the
battery charger connections while the battery is charging.
Always turn the battery charger off before disconnecting the
battery connections. Ventilate the compartments containing
batteries to prevent accumulation of explosive gases.
Use a 12 VDC battery with a minimum rating of
525 CCA.
1. Verify that the generator set master switch is in the
OFF/RESET position.
2. Ensure that the starting battery is fully charged
before placing the battery in service.
3. Clean the battery posts and/or adapters if
necessary.
4. Install battery post adapters, if needed.
5. See dimension drawing ADV-7000A in Section 4
for the battery rack location. Place the battery on
the battery rack on the skid.
