How do I use an LR97D electronic overload relay with a single phase motor or load?

To use the LR97D electronic overload relay with a single phase motor or load, the LR97D unit must be set in single phase operation. The dip switch SW1 must be set to 1 phase on the front face of the relay.

See page 1 of the attached PDF to see the location of this dip switch.
