Cabling
•
For the power cables, it is recommended to use Radox Elastomer S, screened automotive cable or
equivalent cable with similar specifications.
•
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).
