Installation Electrical

Motor Cable

The motor must be connected to terminals U/T1/96, V/
T2/97, W/T3/98. Earth (ground) 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 frequency converter output
connected as follows:

Motor Rotation Check

The direction of rotation can be changed by switching
two phases in the motor cable or by changing the setting
of 4-10 Motor Speed Direction.

A motor rotation check can be performed using1-28
Motor Rotation Check and following the steps shown in
the display.

AC Mains Connection

• Size wiring is based upon the input current of the
frequency converter
• Comply with local and national electrical codes for
cable sizes
• Connect 3-phase AC input power wiring to terminals
L1, L2, and L3 (see Figure 1)

Motor connection
• Earth (ground) the cable in accordance with the
instructions provided
• All frequency converters may be used with an isolated
input source as well as with earth (ground) reference
power lines. When supplied from an isolated mains
source (IT mains or fl oating delta) or TT/TN-S mains
with a grounded leg (grounded delta), set 14-50 RFI
Filter to OFF .
When off, the internal RFI fi lter capacitors between
the chassis and the intermediate circuit are isolated to
avoid damage to the intermediate circuit and to reduce
earth (ground) capacity currents in accordance with
IEC 61800-3.
