1.3.5 Connecting to Line Power and Motor
The adjustable frequency drive is designed to operate all
standard three-phased asynchronous motors.
The adjustable frequency drive is designed to accept line
power/motor cables with a maximum cross-section of
0.006 in

•
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 Instruction MI02B.

Also see EMC-Compatible Installation in Design
Guide MG02K.
1. Mount the ground wires to the ground 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.
NOTE!
See back of terminal cover for outlines of control terminals
and switches.
NOTE!
Do not operate switches with power on the adjustable
frequency drive.
6-19 Terminal 53 Mode must be set according to Switch 4
position.
