3.6.6. 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.
3.6.7. 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 VLT frequency converter output connected as follows:
Terminal No.
96, 97, 98, 99
• Terminal U/T1/96 connected to U-phase
• Terminal V/T2/97 connected to V-phase
• Terminal W/T3/98 connected to W-phase
The direction of rotation can be changed by switching two phases in the motor cable or by changing the setting of par. 4-10.
F Enclosure Recommendations/Requirements
Recommended F1/F3 connections: Motor phase cable quantities should be 2, 4, 6, or 8(multiples of 2) to obtain equal amount of wires attached to both
inverter module terminals. The cables are recommended to be equal length between the inverter module terminals and the first common point of a phase.
The recommended common point is the motor terminals.
