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 termi-
nals. 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.

C - 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 on the 40 kW will handle wire sizes #6 AWG
to 250 MCM and should be torqued to 250 in. lbs. The lugs on the
30 kW will accommodate #6 AWG to 250 MCM and should be
torqued to 250 in. lbs.

D. 120 Volt Terminal Block, This terminal block is provide for the
120 volt/ 15 amp feed from customers distrubution panel for the
block heater and the trickle charger.

***** WARNING *****

****************

A main line circuit breaker has been provided inside the genera-
tor housing. During all wiring installations make sure the breaker
is in the off position and the generator operation switch is in the
off position.

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.

All wires should be installed in rigid or flexible conduit. (Knock-
outs are provided in the control box).

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 grounded to earth ground if required. Check with your local
codes. Generally a 6 foot copper rod driven into the earth will
provide a proper earth ground.

D.C. ELECTRICAL
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
various 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.
