4.1.5 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 elec-
trical connection. Use a torque wrench to ensure correct torque

4.1.6 Shielded Cables
It is important that shielded and armoured cables are connected in a proper way to ensure high EMC immunity and low emissions.
Connection can be made using either cable glands or clamps:
• EMC cable glands: Generally available cable glands can be used to ensure an optimum EMC connection.
• EMC cable clamp: Clamps allowing easy connection are supplied with the frequency converter.
4.1.7 Motor Cable
The motor must be connected to terminals U/T1/96, V/T2/97, W/T3/98. Earth to terminal 99. All types of three-phase asynchronous standard motors
can be used with a frequency converter unit. The factory setting is for clockwise rotation with the frequency converter output connected as follows:
