High voltage connections
The high voltage connections have a common ground connector.

The voltage on the LV side (U
(U
). If a higher voltage is applied to the LV side, current will immediately flow through the
HV
diodes of device and the HV side voltage will increase to the same level as the LV side voltage.
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 specific 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.
