Setting up SP12 for single phase
operation
To convert a Sensor SP12 Portable Pack from three phase to
single phase operation, follow these steps:
1. Disconnect power from all Cam-Loks.
2. Remove all dimmer modules from the Portable Pack,
exposing the bus bars and connectors.
3. Remove the screws at both ends of the two inch long
copper bars that connect the phase B connector to the
phase B bus bar. Loosen the screws at the left end of the
bars.
4. Use the top bar to connect the phase A connector to the
phase B connector, as shown below.
5. Use the bottom bar to connect the phase B connector to
the phase C connector, as shown below.
6. Tighten all screws to 40 inch/pounds of torque.
7. Replace dimmer modules.
8. Connect power to the A and C phase Cam-Loks. Do not
connect power to the B phase Cam-Lok.
Single phase operation is automatically detected by both
the CEM and the MPE, so no additional configuration is
necessary.
