3.5 Connecting

3.5 Connecting
When connecting, avoid bending cable lugs or cables, or the use of other forms of mechanical
force on the terminals. Otherwise, leakage could disable the safety device (overpressure
disconnector).
Provide sufficient mechanical strain relief for the cable.
Ensure firm fixing of terminals, fixing torque to be applied as per individual specification.
In any case, the maximum specified terminal current may not be exceeded. Please refer to the
technical data of the specific series.
Parallel connection of capacitors via the terminal is not recommended.

Note
Prevent heating the cables.
The connection cables to the capacitor should be dimensioned for a current of at least 1.5 times
the rated current so that no heat is conducted into the capacitor.
