appropriately for safety reasons. Apply local
safety regulations.

High-frequency earthing: Keep the earth wire
connections as short as possible.
Connect the different earth systems at the lowest possible
conductor impedance. The lowest possible conductor
impedance is obtained by keeping the conductor as short
as possible and by using the greatest possible surface area.
The metal cabinets of the different devices are mounted
on the cabinet rear plate using the lowest possible HF
impedance. This avoids having different HF voltages for
the individual devices and avoids the risk of radio
interference currents running in connection cables that
may be used between the devices. The radio interference
will have been reduced.
In order to obtain a low HF impedance, use the fastening
bolts of the devices as HF connection to the rear plate. It is
necessary to remove insulating paint or similar from the
fastening points.
3.4.6.3 Safety Earth Connection
The frequency converter has a high leakage current and
must be earthed appropriately for safety reasons according
to IEC 61800-5-1.
WARNING
The earth leakage current from the frequency converter
exceeds 3.5 mA. To ensure a good mechanical connection
from the earth cable to the earth connection (terminal 95),
the cable cross-section must be at least 10 mm
2
or 2 rated
earth wires terminated separately.
3.4.6.4 Final Setup Check
To check the setup and ensure that the frequency
converter is running, follow these steps.
Step 1. Locate the motor name plate
NOTE
The motor is either star- (Y) or delta- connected (Δ). This
information is located on the motor name plate data.
