Low Voltage connections to signal fault contacts, transfer switch communication, remote LED and auxiliary 12VDC power are
made via a removable ten-pin 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:
System Connectors
A
- 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.
B
- Transfer Switch Communication ― Connect to transfer
switch control board for communication interface using
18AWG copper twisted pair wire.
C
– LED ― Not Used.
D
- +12 Volt DC, .5 Amp Output ― Internal power supply.
E
- 240 Volt Utility ― Use to hook up the 240V utility leads
from the transfer switch to the generator.
F
– Ten-pin Connector Plug
G
– Two-pin Connector Plug
• For power output connection, use #6 AWG minimum 300 volt 90°C copper wire, (ref. NEC Table 310.16, 100 ft.
Use National Electric Code for correction factors and wire size calculations).
• For utility circuit connection use #14 AWG minimum 300 volt 90°C copper wire.
• For transfer switch communication use #18 AWG twisted pair conductors, no greater than 200 ft in length, 300 volt 90°C
copper wire.
• When connecting to the connector plugs, fasten only one wire to each connector screw.
• Torque connector plug screws to 7 in-lb (7.9 Newton meter).
