Terminal Strip Connections
(DEC 3+)
The 16-light controller circuit board has terminal strips
for use in connecting a controller connection kit. Do not
connect accessories directly to the controller terminal
strip(s). Connect accessories to either a controller
connection kit or dry contact kit. Connect the dry contact
kit(s) to the controller connection kit. Connect alarms,
battery chargers, remote
accessories to the dry contact kit relay(s).
The 16-light controller has two terminal strips, TB1 and
TB2, on the controller circuit board, and prime power
choices are made on TB2.

See Figure 6-38, Figure 6-39, and Figure 6-40 for

Lower the controller circuit board panel until it is lying flat
when connecting the dry contact kits to the controller
TB1 terminal strip. Route dry contact relay leads
through the controller grommet and guide loops to the
circuit board terminal strip. Place the controller circuit
board panel flat to ensure adequate slack in the dry
contact relay leads.
accessory connections refer to the accessory wiring
diagrams in the Wiring Diagram Manual and the
instruction sheet accompanying the kit.
Note: Not all terminals are used for all generator sets
(see appropriate wiring diagrams for specific
generator set models).
Note: To use the prime power mode, use jumpers to
connect TB2-1P to TB2-2P, TB2-3P to TB2-4P,
and TB2-3 to TB2-4. To deactivate the prime
