System Connectors

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 important connections. Count down to the proper pin location on the control board since visual alignment
with the decal can be misleading:
A - Ten-pin 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 twisted pair wire.
