1.4.4 Motor connection
Connect the motor to terminals 96, 97, 98. Connect earth to terminal 99.
See
Technical data
for correct dimensioning of cable cross-section.
All types of three-phase asynchronous standard motors can be connected to a frequency con-
verter. Normally, small motors are star-connected (230/400 V,
Δ
/ Y).
NB!
In motors without phase insulation paper, an LC filter should be fitted on the output
of the frequency converter.
The factory setting is for clockwise rotation.
The direction of rotation can be changed by switching two phases on the motor terminals.
1.4.5 Parallel connection of motors
The frequency converter is able to control several motors connected in parallel.
Please consult the Operating Instructions for further information.
NB!
Be aware that the total cable length, listed in the section
EMC Emission
.
NB!
