1.3.6 Connecting to Mains and Motor
The frequency converter is designed to operate all standard three-phased asynchronous motors.
The frequency converter is designed to accept mains/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, please see instruction MI.02.BX.YY.
• Also see EMC-Correct Installation in Operating Instruction MG.02.AX.YY.
Step 1: First, mount the earth wires to earth terminal.
Step 2: Connect motor to terminals U, V and W.
Step 3: Mount mains supply to terminals L1/L, L2 and
L3/N (3-phase) or L1/L and L3/N (single-phase) and
tighten.

wires.
1.3.7 Control Terminals
All control cable terminals are located underneath the
terminal cover in front of the frequency converter. Re-
move the terminal cover using a screwdriver.
See back of terminal cover for outlines of
control terminals and switches.
Do not operate switches with power on the
frequency converter.
Parameter 6-19 must be set according to
Switch 4 position.
Illustration 1.3: Removing terminal cover.
Switch 1: *OFF = PNP terminals 29
ON = NPN terminals 29
Switch 2: *OFF = PNP terminal 18, 19, 27 and 33
ON = NPN terminal 18, 19, 27 and 33
Switch 3: No function
Switch 4: *OFF = Terminal 53 0 - 10 V
ON = Terminal 53 0/4 - 20 mA
* = default setting
