Converting SCR 6 or 8 between Phases

The SCR 6 and 8 Rotisserie can be converted from 3 phase to 1 phase or from 1 phase to 3 phase in the field.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Converting a SCR 8 from 3 phase to 1 phase

1. Remove electrical power supplied to the unit.

2. Replace the terminal block with a 1 phase terminal block.

3. Replace the contactor with a 1 phase contactor.

   IMPORTANT: The phase 1 configuration will pull more amperage so a higher amperage rated contactor is required.

4. On the power supply side of the contactor, connect the L1 and L2 incoming power with a jumper between the L2 and L3 terminal.

5. On the load side of the contactor, connect wires:

   1. 20, 24, and 53 to L1 terminal

   2. 18 and 27 to L2 terminal

   3. 25 and 52 to L3 terminal

6. Replace the power cord.
