System Connectors

Low voltage connections to signal fault contacts, transfer switch communication, remote LED and auxiliary 12VDC power are
made via a removable ten-pole connector plug. Compare this illustration with your generator to familiarize yourself with the
location of these connections. Count down to the proper pin location on the control board since visual alignment with the
decal can be misleading:
A - 10 Pole Connector Plug
B - Fault Contacts — Use NO, COM and NC to hook up 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.
C - Transfer Switch Communication — Connect to transfer
switch control board for communication interface using
18AWG copper twisted pair wire.
IMPORTANT:
• F or 30kW power output connection, use #1/0 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.)
• F or Utility Circuit connection use #14 AWG minimum 300 volt 75°C-90°C copper wire
• F or transfer switch communication use #18 AWG twisted pair conductors, no greater than 200 ft in length, 300 volt
75°C-90°C copper wire
• F asten only one wire to each connector screw.
• T orque connector plug screws to 7 in-lb (7.9 Newton meter).

D - Remote LED Output — Use this to hook up 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.
E - +12 Volt DC, .5 Amp Output — Internal auxiliary
power supply.
