A.C. ELECTRICAL CONNECTIONS
This AC terminal block is covered by a lockable access cover. Access
for routing the wires into the terminal block is provided via a small
access door just to the left of the main control panel door. You will also
find your convenience receptacles located behind this small door. All
receptacles located here have their own circuit breaker for protection.
NEUTRAL LUGS:
These lugs are isolated from ground and provided for you to connect
your neutral wire from the transfer switch to the generator. Lugs will
handle up to 2/0 wire. Torque lugs to 150 in. lbs. using #1 and #2 wire
and 180 in. lbs. for 1/0 & 2/0 wire.
GROUND LUG:
These ground lugs are bonded to ground and are provided for you
to connect your ground wire from the transfer switch to. The lugs will
accommodate up to 2/0 wire. Torque lugs to 150 in. lbs. using #1 & #2
wire and 180 in. lbs. for 1/0 & 2/0 wire.
L1, L2, & L3 POWER OUTPUT LUGS:
The full power terminal block is capable of handling full generator
output at any of the selected voltages. For single phase 120/240
connect to L1 and L3, the third leg L2 is not powered or used. Lugs will
handle up to 2/0 wire. Torque lugs to 150 in. lbs. using #1 & #2 wire
and 180 in. lbs. for 1/0 & 2/0 wire. In the 120/240V 3-Ph configuration
with the wild leg (208 line to neutral) is wired to the L2 position.
WARNING: PERSONAL DANGER:
This unit is shipped with the neutral and ground unbonded. If the unit
is to be used as a stand-alone generator, you must bond neutral and
ground together either at this terminal block or somewhere in your
system.
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 will provide a
proper earth ground.

CAM-LOCK CONNECTIONS
This unit is equipped with Com-Lock connector, located behind the
rear, right door panel. These Cam-Locks are connected to the full load
terminal blocks and are capable of providing full generator output in
all voltage configurations. The mating connectors are model CL2FB,
which are available with different ire size capabilities.
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.
CUSTOMER REMOTE START CONNECTIONS TERMINALS. This
can be either an automatic transfer switch or just a remote switch in
a job trailer. This feature requires a relay closure between the two
connections on the terminal block to put the unit into an auto-start
mode. The auto-start mode has both a start delay and a cool down
delay built into the DSE 7310 MKII
Torque Screws to 9.6 in. lb. using 14 to 16 awg copper wire with lugs.
Note: Any relay closure can be used to start and stop this generator. As
long as the contact stays closed the engine generator set will continue
to run. Once the relay is opened the unit will shut down and remain in
the standby mode until the remote start relay is closed again.
ESTOP- & ESTOP+. Remote Emergency Stop terminals. 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 either the jumper installed or a remote N/C switch
installed.
