3.6.7. Shielded Cables
It is important that shielded and armored cables are connected properly to ensure high EMC im-
munity and low emissions.
Connection can be made with 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 for easy connection are supplied with the adjustable
frequency drive.
3.6.8. Motor cable
The motor must be connected to terminals U/T1/96, V/T2/97, W/T3/98. Ground to terminal 99.
All types of three-phase asynchronous standard motors can be used with an adjustable frequency
drive unit. The factory setting is for clockwise rotation with the VLT adjustable frequency drive
output connected as follows:
Terminal No.

Ground/Earth
• 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 chang-
ing the setting of par. 4-10.
