Make sure that the sensor probe is pointing down once installed. Tape the sensor in
Place while the silicone hardens. Route the generator end of the sensor cable through
the generator hole marked CONTROL WIRING ENTRY using the control cable strain
relief. Plug the sensor cable into the RM TEMP connector on the printed circuit board
assembly. See diagram 12.
6. WIRING THE GENERATOR CONTROL CABLES
Choose one generator to be your “Master” unit. This generator will control the other one
or two “slave” generators in the system. If the generators are not the same size (kW),
the largest wattage generator should be the master.
At the Master generator: Route the generator end of the control cable through the
generator hole marked CONTROL WIRING ENTRY using the strain relief provided.
Plug the control cable into the T100 metal shielded connector on the printed circuit board assembly. See diagram 12.
Connect a shielded control cable to the Master generator’s OUT1 jack and route this cable out the Master’s CONTROL WIRING ENTRY and into the fi rst slave
generator though its CONTROL WIRING ENTRY hole. Connect this cable to the slave’s T100 jack. If a second slave generator is to be used, route another control
cable in the same manner from the Master’s OUT2 jack to the slave’s T100 jack. Note: If additional room is needed at the Master generator for routing the slave
cables, a knock out is provided next to the CONTROL WIRING hole. Secure all cables.

* 208 VAC wired units must be supplied with a minimum of 195 VAC while operating (heating).
Unit is rated for copper wire only. All wire is UL approved 300V 75°C minimum unless otherwise specifi ed.
** Single phase 12kW & 14kW require two separate line feed circuits.
