3.3.7 Shielded Cables

WARNING
Danfoss recommends to use shielded cables between the
LCL filter and the AFE unit. Non-shielded cables can be
used between transformer and LCL filter input side.
It is important that shielded and armored cables are
connected in a proper way to ensure the high EMC
immunity and low emissions.
The 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.
3.3.8 Motor Cable
The motor must be connected to terminals U/T1/96, V/
T2/97, W/T3/98. 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

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.
Motor rotation check can be performed using 1-28 Motor
Rotation Check and following the steps shown in the
display.
F frame Requirements
F8/F9 requirements: 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.
F10/F11 requirements: Motor phase cable quantities must
be multiples of 2, resulting in 2, 4, 6, or 8 (1 cable is not
allowed) to obtain equal amount of wires attached to 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.
F12/F13 requirements: Motor phase cable quantities must
be multiples of 3, resulting in 3, 6, 9, or 12 (1, 2, or 3
cables are not allowed) to obtain an equal amount of wires
