E: FULL POWER OUTPUT & NEUTRAL TERMINAL BLOCK :
See A.C. Electrical Connections in this manual.
F: DOOR SAFETY SWITCH:
This safety switch is connected to the DSE 7310 MKII engine control
and will shut the unit down any time door is opened with the unit
running. This prevents someone from accidentally contacting the main
power connection with the unit running. This unit will not start if the
door is not closed and latched.
G: WIRE ENTRANCE HOLES:
These hole have been specifically provided for you to route your
full power leads through to the output lugs. The routing holes were
provided to insure that no small child or curious adult can reach inside
and come into contact with the main output lugs with the unit running.
H: 120V 20 AMP 3-WIRE RECESSED SHORE POWER PLUG:
NEMA Spec 5-20. This panel mounted plug is designed to plug directly
in a standard 20 amp receptacle on a extension cord. The plug when
connected will provide power to the block heater and the battery trickle
charger mounted inside the generator enclosure. This can be used
when the set is used in a standby application to keep the engine warm
and the battery charged or in your rental yard to keep the battery
charged up. This receptacle is to be powered by a GFCI circuit and
installed in accordance with the United States National Electric Code.
I: 2 - 120V 20 AMP GROUND FAULT INTERRUPTER DUPLEX:
These duplex receptacles are protected by 20 amp circuit breakers
mounted just above the duplexes. The “T” slot design both 15 and 20
amp 120V cords can be plugged in.
J: 2- 120/240V 50 AMP 4-WIRE TWISTLOCK:
These receptacles are rated for dual voltage, 120 or 240V use. It is
a 4-wire receptacle, with a center grounding pin. 4-wire drop cords
plugged into this receptacle may be split into 120V receptacles at a
distrobution box. Each receptacle is protected by a two pole 50 amp
circuit breaker mounted just above it. THIS RECEPTACLE UTILIZES A
HUBBLL PLUG PART # CS6365.
K: 250V 50 AMP CIRCUIT BREAKERS:
These circuit breakers protect the 2 - 50 amp twistlock receptacles (H).
L: 120V 20 AMP CIRCUIT BREAKERS:
These two push button 20 amp circuit breakers protect the two GFCI
receptacles (G).
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.
ELECTRICAL CONNECTIONS
NOTICE: CLASS 1 WIRING METHODS ARE TO BE USED FOR ALL
FIELD WIRING CONNECTIONS TO TERMINALS OF A CLASS 2
CIRCUIT
All wiring must be completed in accordance with the National Electric
Code as well as any state and local codes.
You must pay particular attention to wire size requirement for
the amperage of service you are dealing with. The table below
provides you guidance on wire sizing based on both wire type and
amperage.
Wire amperages have been derated for 40° C ambient
temperatures operation.
WARNING:
Make sure the generator is disconnected from the battery to prevent
accidental starting.
RECEPTACLE PANEL
A: 208/240 VOLT MAINLINE CIRCUIT BREAKER:
This is the low voltage mainline circuit breaker feeding the full output
terminal block. This circuit breaker is used when the selector switch
is in the 120/208V 3-PH, 120/240V 3-PH, or 120/240V 1-PH switch
position.
B: 480 VOLT MAINLINE CIRCUIT BREAKER:
This is the high voltage mainline circuit breaker feeding the full output
terminal block. This circuit breaker is used when the selector switch is
in the 277/480V 3-PH position.
C: CIRCUIT BREAKER LOCKING BAR:
Select and turn on either the high voltage breaker (480V) or the low
voltage breaker (208/240V), depending on which position you have the
selector switch in. This bar prevents both breakers from being turned
on at the same time.
D: REMOTE START/E-STOP TERMINAL BLOCK
This terminal block provides the customer two different connections.
Torque screws to 9.6 in. lb. using 14 to 16 AWG copper wire with lugs.
