Mains Torque
When tightening all electrical connections it is very
important to tighten with the correct torque. Too low or too
high torque results in a bad electrical connection. Use a
torque wrench.

NOTE
Check the name plate to ensure that the mains voltage of
the AFE matches the power supply of the crane.
Ensure that the power supply can supply the necessary
current to the frequency converter.
Ensure that the fuses have the correct current and voltage
rating.
