For the power cables, it is recommended to use Radox Elastomer S, screened automotive cable
or equivalent cable with similar speci cations.
Use only EMI-shielded power cables to make sure the correct operation of the electric device
and to minimize the radiated emissions. Cable shields must be connected to the electric device
ground at both ends of the cable. All Danfoss products use EMI-shielded cable glands for
power connections.
Wiring
To make sure of correct and steady operation, use EMI-shielded cables for the control signals of the
electric device. Cable shields must be connected to the electric device ground at both ends of the
cable.

Make sure the power cables exit straight from the terminals and do not rub against the sharp cable through-holes or
other sharp edges which could wear out the cable insulation over time.
Do not place any excess weight on the connection box lid(s).
The electric device must be installed and connected according to the instructions.
Make sure that all the connected applications are connected to the electric device according to
the product speci c operating voltage.
The electric device is delivered with the power terminal cover mounted. To access the power
connections, remove the mechanical safety feature and the connection box lid.
