Electrical data, connections and wiring
Danfoss SH scroll compressors are available in five different motor voltages as listed below.
Motor voltage code
Nominal voltage
50 Hz
Voltage range**
Nominal voltage 200-230V - 3 ph
60 Hz
Voltage range** 180-253 V
* SH295 and 485
** 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.
Electrical power is connected to the compressor
terminals by Ø 4.8 mm (3/16") screws.
The terminal box is provided with a Ø 25.5 mm
(ISO25) and a Ø 29 mm (PG21) knockouts.
The terminal box is provided with a
Ø40.5 mm hole (ISO40) for power supply and a
Ø16.5 mm knockout (ISO16).
