Electrical data, connections and wiring
Danfoss scroll compressors DSH are available in four different motor voltages as listed below.
Electrical power is connected to the compressor
terminals by Ø 4.8mm (3/16") screws. The
maximum tightening torque is 3Nm. Use a 1/4"
ring terminal on the power leads.
Cable gland or similar protection
component must be used on electrical box's
knockouts to against accidental contact with
electrical parts inside.

The terminal box is provided with a Ø 25.5mm
(φ1 inch) (ISO25) and a Ø 29mm (φ1.14) (PG21)
knockouts.
The terminal box is provided with a Ø 40.5mm
(φ1.59inch) hole (ISO40) for power supply and a
Ø 16.5mm (φ0.65inch) knockout (ISO16).

*** 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.
Vavg = Mean voltage of phases 1, 2, 3.
V1-2 = Voltage between phases 1 and 2.
V1-3 = Voltage between phases 1 and 3.
V2-3 = Voltage between phases 2 and 3.

imbalance
= x 100
The maximum allowable voltage imbalance is
2%. Voltage imbalance causes high amperage
over one or several phases, which in turn leads to
overheating and possible motor damage. Voltage
imbalance is given by the formula:
