Electrical Installation

4.5.3 Shielded Cables

It is important to connect shielded cables properly to
ensure high EMC immunity and low emissions.
Connection can be made using either cable glands or
clamps:
•
EMC cable glands: Generally available cable
4 4
glands can be used to ensure an optimum EMC
connection.
•
EMC cable clamp: Clamps allowing easy
connection are supplied with the unit.

4.6 Motor Connection

4.6.1 Motor Cable

Connect the motor to terminals U/T1/96, V/T2/97, W/T3/98,
on the far right of the unit. Ground to terminal 99. All
types of 3-phase asynchronous standard motors can be
used with a frequency converter. The factory setting is for
clockwise rotation with the frequency converter output
connected as follows:
Terminal No.
96, 97, 98
99
Table 4.2 Terminal Functions
•
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 2
phases in the motor cable or by changing the setting of
4-10 Motor Speed Direction.
Motor rotation check can be performed via 1-28 Motor
Rotation Check and following the steps shown in the
display.

F-frame requirements
Use motor phase cables in quantities of 2, resulting in 2, 4,
6, or 8 to obtain an equal number of wires on both
inverter module terminals. The cables are required to be
equal length within 10% between the inverter module
terminals and the first common point of a phase. The
recommended common point is the motor terminals.
Output junction box requirements
The length, minimum 2.5 m, and quantity of cables must
be equal from each inverter module to the common
terminal in the junction box.
NOTICE
If a retrofit application requires an unequal number of
wires per phase, consult the factory or use the top/
bottom entry side cabinet option, instruction 177R0097.

4.6.2 Brake Cable

Frequency converters with factory installed brake chopper
option
(Only standard with letter B in position 18 of type code).
