1. You may only use copper wire of class 1, 75°C (for compliance with the UL in
frame sizes A to C).
2. Ensure that the appropriate circuit breakers or fuses with the specified current
rating are connected between the power supply and the drive.

Cable cross-section of the grounding conductors
The material of the protective grounding conductor must be the same as the
material of the power cable. If this is not the case, the specific resistance of the
protective grounding conductor must not be higher than the specific resistance of
the power cables. The relevant diameter of the power cables is the diameter of the
line supply cable, and not the diameter of the motor cables.
In the case of power cables up to 35 mm
section of at least 10 mm² (16 mm² Al).
It is always advisable to use a 16mm
For power cables with a diameter of more than 35 mm
conductor must have at least half of the size of the cross-section of the power
cable.
