1.3.4 Connecting to Line Power and Motor
The adjustable frequency drive is designed to operate all
standard 3-phased asynchronous motors.
The adjustable frequency drive is designed to accept line
power/motor cables with a maximum cross-section of
4 mm
2
/10 AWG (M1, M2 and M3) and maximum cross-
section 16 mm
2
/6 AWG (M4 and M5).
•
Use a shielded/armored motor cable to comply
with EMC emission specifications, and connect
this cable to both the decoupling plate and the
motor metal.
•
Keep motor cable as short as possible to reduce
the noise level and leakage currents.
•
For further details on mounting of the
decoupling plate, see VLT Micro FC 51 Decoupling
Mounting Plate Instructions.
•
Also see EMC-compatible Installation in the
Design Guide.
1. Mount the ground wires to PE terminal.
2. Connect the motor to terminals U, V and W.
3. Mount line power supply to terminals L1/L, L2
and
L3/N (3-phase) or L1/L and L3/N (single-phase)
and tighten.

Control Terminals
All control cable terminals are located underneath the
terminal cover in front of the adjustable frequency drive.
Remove the terminal cover using a screwdriver.
NOTICE!
See back of terminal cover for outlines of control
terminals and switches.
Do not operate switches with power on the adjustable
frequency drive.
6-19 Terminal 53 Mode must be set according to Switch 4
position.
