System Connections
Except for the power output and grounding connectors, all signal wire connections are made to removable two- or ten-pin connector
plugs. Compare this illustration with your generator to familiarize yourself wtih the location of these important connections.
Count
down to the proper pin location on the control board since visual alignment with the decal can be misleading:
A- Fault Contacts
—
Use NO, COM, and NC to hook up an
optional phone dialer or a siren, light, etc. to alert you in case
of a fault. Contacts reverse state (NO goes to NC and vice
versa) upon a fault condition.
B - Transfer Switch Communication
—
Use TxRx and TxRx
GND to connect to transfer switch control board for
communication interface.
C - Remote LED Output
—
Use +LED and GND to connect
the remote LED supplied with the generator. The remote LED
will turn on and off in a series of blinks if certain faults are
detected in the generator.
D - +12 Volt DC,.5 Amp Output
—
Auxiliary power supply.
Use +12VDC and GND to connect installer-supplied
accessories (siren, light, etc).
E - 240 Volt Utility Connection
—
Use to connect the 240V
utility leads from the transfer switch fuses to the generator.
F - Ten-pin Connector Plug
G - Two-pin Connector Plug
NOTICE:
• For power output connection, use #8 AWG
minimum 300 volt 75°C-90°C copper wire, (ref.
NEC Table 310.16, 100 ft. Use National Electric
Code for correction factors and wire size
calculations).
• For 240 Volt Utility Circuit Connection, use #14
AWG minimum 300 volts 75°C-90°C copper wire.
• For transfer switch communication use #18 AWG
twisted pair conductors, no greater than 200 ft. in
length, 300 volt 75°C-90°C copper wire.
• When connecting to the connector plugs, fasten
only one wire to each connector screw.
• Torque connector plug screws to 7lb.-in.(8 Nm).
