Electric Connection For High-Voltage (2.2 Kv Up To 11 Kv); Direction Of Rotation - VEM W41 Series Installation, Operating And Maintenance Instructions

Installation, Operating and Maintenance Instructions (Translation)
supply cables in the terminal box of the motor. The nuts of the connection screws have to be fastened without
force. Before connecting the power line, the existing motor connections must eventually be retightened. The termi-
nals for connecting additional devices and monitoring units are situated in the terminal box (in the additional termi-
nal box only when ordered accordingly).
CAUTION ! The distances between live parts and against ground must not go below the following values:
Rated voltage U [V]
N
Minimum distance [mm]

The arrangement of cable lugs, nuts and counter nuts must be done according to the drawings from chapter 20
(Design of terminal boxes).

10.2 Electric connection for high-voltage (2.2 kV up to 11 kV)

10.3 Direction of rotation

The marking of the terminals is done according to DIN EN 60034-8 / IEC 60034-8. In standard design motors are
suitable for both directions of rotation. When the phases L1, L2, L3 are connected correct at the terminals U-V-W
the motors rotate in clockwise direction; that means seen from the drive end the direction of rotation is in clockwise
direction.
For motors only suitable for one direction of rotation the direction is marked by an arrow on the motor, on
the fan or on the name plate. When these motors shall be operated in the other direction please contact
the manufacturer first!
For direct starting and pole-changing motors with separate winding the direction of rotation can be reversed by
changing two of the line conductors on the terminal board. For motors with star/delta-starting and pole-changing
motors with Dahlander winding two line conductors must be changed at the supply to the motor switch.
A motor with only one shaft end or two shaft ends with different diameters the direction of rotation is that one seen
from the front end of the only shaft end or the bigger shaft end.
