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

Control circuit
The terminal box is provided with Ø 50.5 mm
(ISO50) (UL 1"1/2 conduit) hole with possible
Ø 63.5 mm (ISO63) (UL 2" conduit) knockout for
power supply and 2 x Ø 22.5 mm (PG16)
(UL 1/2" conduit) knockouts for safety control
circuit.
The temperature inside the terminal box may not
exceed 70°C. Consequently, if the compressor is
installed in an enclosure, precautions must be
taken to avoid that the temperature around the
compressor and in the terminal box would rise
too much. The installation of ventilation on the
enclosure panels may be necessary. If not, the
electronic protection module may not operate
properly. Any compressor damage related to this
will not be covered by Danfoss warranty. In the
same manner, cables must be selected in a way
to insure that terminal box temperature does not
exceed 70°C.
