Motor protection module
The motor protection modules come preinstalled within the terminal box. Phase sequence protection connections
and thermistor connections are pre-wired and should not be removed.
The module must be connected to a power supply of the appropriate voltage. The module terminals are 6.3 mm
(0.25 inch) size Faston type.

NOTE:
Voltage range
: Nominal voltage ± 10%. The voltage range indicates where the compressor can run in the majority
of the application envelope. A boundary voltage supply which accumulates under specific conditions such as high
ambiance, high superheat, or map boundary conditions, may lead to a compressor trip.
