4.6.6 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.
4.6.7 Motor Cable
The motor must be connected to terminals U/T1/96, V/T2/97, W/T3/98 located on the far right of the unit. 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:
