D.C. ELECTRICAL CONNECTIONS
All DC connections are completed on the terminal strip just below
the engine control. All DC connection must be separate conduit. You
cannot mix AC and DC leads at the same conduit.
CONNECTION BOX TERMINALS
Wire size requirements for each of the connections may vary but
terminal lugs should be used for all connections. Torque spec for
terminal lugs is 9 in. lbs.

F: NEUTRAL TO GROUND LEAD LUG:
This lug is provided on the neutral terminal block to allow you to run
a neutral to ground lead if you are using the generator in a stand
alone application. This would be an application where there is not a
distribution panel and no other ground to neutral bond in the wiring
system. If a grounding wire is attached here, remove the floating
neutral label in the panel. This will not be used when you are wiring a
generator and transfer switch into an existing power system.
WARNING:
A mainline circuit breaker has been provided inside the generator
housing. During all wiring installations, make sure the breaker is in the
OFF position and the generator operating switch is in the OFF position.
WARNING: EQUIPMENT DAMAGE:
When installing a three-phase 240 Volt system, be sure you know
which lead is the high voltage “wild” leg (208 Volt line to neutral). The
generator normally carries the high voltage on the G2 lead.
All wires should be installed in rigid or flexible conduit (knockouts are
provided in the control box).
GROUNDING
A grounding lug has been provided on the engine generator set and
the generator set must be properly grounded to good earth ground.
Generally an 8 foot copper rod driven into the earth wil provide a proper
earth ground.
labeled START is your remote start lead. Closing these two leads
together will signal the DSE7310 to go into an autostart mode and start
up the generator.
Depending on the distance, 14 to 16 gauge standard wire should be
used. It is suggested that these wires be labeled S1 (ground) and S2
(start). The terminal blocks are designed to use terminal lugs on all
wires and the screws should be torqued to 9.6 in. lbs.
Note: Any relay closure can be used to start and stop this generator.
As long as the contact stays closed, the generator set will continue to
run. Once the relay is opened, the unit will shut down and remain on
standby mode until the remote start relay is closed again.
B. ESTOP - & ESTOP +.
These two terminals are shipped with a jumper installed. If your
application requires the installation of a Remote Emergency Stop
switch, remove the jumper and wire your switch to these terminals. This
unit will not start and run without the jumper installed or a remote N/C
switch installed.
C. BATTERY CHARGER FAILURE.
Battery charger failure relay input from remote battery charger to
DSE7310 controller.
D. REMOTE DISPLAY PANEL INTERFACE TERMINALS.
These interface terminals are prewired to allow for the connection os
a remote display. This display allows for the remote annunciation of
alarms at a location such as a nurce’s station or a control room. This
display can be used to meet the remote annunciation requirements
of the NFPA 110 standards (this feature meets the annunciation
requirements in applications requiring NFPA 110 level on protection).
DC INTERCONNECTIONS TO THE ATS
WARNING:
Be sure Engine/Generator is in the OFF position before you make any
DC interconnections.
CAUTION:
Never run the AC and DC wiring in the same conduit.
