4.6.6 Shielded Cables
It is important that shielded and armored cables are connected properly to ensure high EMC immunity and low emissions.
Connection can be made using either cable connectors or clamps:
•
EMC cable connectors: Generally available cable connectors can be used to ensure an optimum EMC connection.
•
EMC cable clamp: Clamps allowing for easy connection are supplied with the adjustable frequency drive.
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. 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 adjustable
frequency drive output connected as follows:
Terminal No.
Function
96, 97, 98, 99
Line power U/T1, V/T2, W/T3
Ground
• 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
