Always double-check the voltage of your power source. Connection to improper voltage can: a) cause severe
damage/harm, or b) cause lights and screen to power on without system function.
All service should only be attempted by a person with appropriate electrical skills, with all equipment disconnected
from power.
The RJ PLUS Series is shipped from the factory with a 240 VAC configuration unless specially ordered. If 120VAC is
needed, move the internal jumpers as shown below. If unsure, seek professional advice.
This set of terminal screws can be located inside of the Control Module, and accessed by removing the six screws
from the back of the Control Module's aluminum base. The factory voltage setting is the 240V configuration, with a
jumper clip inserted between the second and third terminals. The Control Module can be made to accept 110V by
reconfiguring the jumper clips as shown above right, with two jumper clips instead connecting the first & second
terminals, and the third & fourth terminals.
NOTE: Only jumper clips should be moved or reconfigured. No wires should be moved or loosened. Ensure all
connections are tight before returning unit to service.
