EMC INTERFERENCE
Use shielded cables for motor and control wiring, and separate cables for input power, motor wiring, and control wiring. Failure to
isolate power, motor, and control cables can result in unintended behavior or reduced performance. Minimum 200 mm (7.9 in)
clearance is required between power, motor, and control cables.
10.3 Connections
10.3.1 Power Connections
N O T I C E
All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. UL applications
require 75 °C (167 °F) copper conductors. Non-UL applications can use 75 °C (167 °F) and 90 °C (194 °F) copper conductors.
N O T I C E
The plug connector for power is pluggable on drives up to 7.5 kW (10 hp).
The power cable connections are located as shown in
. See for correct dimensioning or motor cable cross-section and
length.
For protection of the drive, use the recommended fuses unless the unit has built-in fuses. Recommended fuses are listed in and .
Ensure that proper fusing complies with local regulations. The connection of mains is fitted to the mains switch, if included.

Aluminum conductors
Terminals can accept aluminum conductors, but the conductor surface must be clean, and the oxidation must be removed and
sealed by neutral, acid-free Vaseline grease before the conductor is connected. Furthermore, the terminal screw must be retight-
ened after 2 days due to softness of the aluminum. It is crucial to keep the connection a gas tight joint, otherwise the aluminum
surface oxidizes again.
