Section 5 - Pre-Start Preparation
Before attempting the initial start of the generator set,
be sure to complete the Installation Checklist in
Section 6.
5.1 Electrical System
Verify all electrical connections are secure and all
wiring is complete and inspected. Replace and
secure any access panels that may have been
removed during installation.
5.2 Battery Connections
WARNING
Accidental starting of the generator set can cause
severe personal injury or death. Make sure that
the Run/Off/Auto switch on the control panel is
set to the Off position before connecting the
battery cables.
Starting the unit requires batteries per the model spe-
cific genset data sheet as provided with the genset
(visit www.cumminsnpower.com to locate specifica-
tions). E-Stop the genset before the connection or
disconnection of battery cables. Connect positive
battery cable before connecting negative battery
cable to prevent arcing.
Service the batteries as necessary. If an automatic
transfer switch is installed without a built-in charge
circuit, connect a separate battery charger. A battery
charger is required when the PowerCommand Con-
troller is set to the Awake mode.
5.3 InPower Service Tool General Infor-
mation (PCC)
InPower is a PC based service tool for the Power-
Command Controller (PCC) to be used by Cummins
authorized factory service technicians. InPower is
used to:
• Make adjustments to the controls trims and set-
tings.
• Perform diagnostics and monitoring.
• Create a capture file of the controls trims and
settings.
• Update control calibrations (InPower PRO ver-
sion).
WARNING
Ignition of explosive battery gases can cause
severe personal injury or death. Always connect
negative (-) battery cable last to prevent arcing.
WARNING
Ventilate battery area before working on or near
battery. Arcing at battery terminals, light switch
or other equipment, flame, pilot lights and sparks
can ignite battery gas. Do not smoke, or switch
trouble light ON or OFF near battery. Discharge
static electricity from body before touching bat-
teries by first touching a grounded metal surface.
5.4 PCC Options Pre-Start Checks
All generator set configuration options are set at the
factory except for site related options, (e.g., Lan-
guage, Start/Stop Time Delays, Cycle Crank, Cus-
tomer Fault 1 and 2, etc.
Adjustment of these options are divided into two cate-
gories within the menu driven system. These two cat-
egories are Setup and Controller Configuration/
Adjust.
The Setup submenus are intended for qualified
service personnel only and require a password to
modify these submenus. The Controller Configuration
and Adjust submenus are intended for service per-
sonnel and site personnel.
The Controller Configuration, submenus are used to
change the default language, temperature units, and
pressure units to be displayed in menus.
The Adjust submenus allow site personnel to
calibrate the generator set voltage/frequency, idle
speed and start/stop time delays. For the pre-start
checks, adjustment of only the start/stop delays is
required. Refer to the model specific Power Controller
(PCC) Manual for installation, operator, and service
information per Table 4-1 .
5.5 Start Up Procedure
Refer to the appropriate Operator Manual for impor-
tant safety precautions and recommended proce-
dures for starting the genset and verifying proper
operation. Start the generator set and verify all engine
and generator menus are displaying the correct
values.
