A main line 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 operation 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.
The load current carrying wires (L) and (T) must be sized to
handle the maximum load current without excessive voltage
drop. By code, the wire must be heavy enough to handle the
full current rating of the main line circuit-breaker (or fuse) in the
entrance (or sub-panel) protecting the contactor switch.
See the manual shipped with the Automatic Transfer Switch for
connection locations in the switch. Connections in each switch
will vary depending on the type of switch and the manufacturer.
GROUNDING
A grounding lug has been provided on the engine generator
set to ground to earth ground if required. Check with your local
codes. Generally a 8 foot copper rod driven into the earth will
provide a proper earth ground.

CONNECTIONS
NOTE:
There are various DC connectors on the engine that have
nothing connected to them. This was done intentionally,
these connectors are for END OF LINE TESTING and
other diagnostic tests. They are not used during normal
operations and can just be ignored.
All DC connections are completed on the terminal strip just below
the engine control cabinet.
A - Customer Remote Start CONNECTIONS TERMINALS.
The two remote start leads from the Automatic Transfer Switch
are connected to the two terminals marked 1 & 23. The wire
in terminal labeled #1 is Battery Negative and the wire in the
terminal labeled #23 is your Remote Start lead. Closing these
two leads together will signal the DSE 7310 to go into an auto-
start mode and start up the engine generator.
Depending on the distance, 14 to 16 gauge stranded wire should
be used. It is suggested that these wires be labeled S1 and S23.
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 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.
B - 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..
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 of a
remote display. This display allows for the remote annunciation
of alarms at a location such as a nurses station or a control
room.
*******CAUTION******
Never run the AC and DC wiring in the same conduit.
NOTE: The right hand half of the customer connection
terminal block is for programmable inputs and outputs.
Although these terminals are wired into the DSE7310, they
are not normally programmed. This terminal block has
connections for four programmable inputs and four iutputs
along with one fl ex input and a ground. Consult the factory
at 507-357-6831 before attempting to program these inputs/
outputs.
