installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the following
conditions apply:
• A Type B Device must be used
• The device must be suitable for protecting equipment with a DC component in the
leakage current
• Individual ELCBs should be used for each ACS260

Shield Termination (Cable Screen)
The safety ground terminal provides a grounding point for the motor cable shield. The
motor cable shield connected to this terminal (drive end) should also be connected to
the motor frame (motor end). Use a shield terminating or EMI clamp to connect the
shield to the safety ground terminal.
Incoming Power Connection

General
• ACS260 Drive models are Over Voltage Category III according to EN60664-
1:2007. Auxiliary circuits must be Over Voltage category II.
• Models intended for 380 - 480VAC supply are suitable for use on a circuit capable
of delivering not more than 5kA symmetrical amperes, 480VAC maximum when
protected by Class J Fuses rated.

Cable Selection
• For 3 phase supplies, the mains power cables should be connected to L1, L2, and
L3. Phase sequence is not important.
• The cables should be dimensioned according to any local codes or regulations.
• The cable must be sufficient to carry the drive load current.
• For compliance with CE and EMC requirements, refer to section Electrical Rating
Tables .
• A fixed installation is required according to IEC61800-5-1 with a suitable
disconnecting device installed between the ACS260 and the AC Power Source.
The disconnecting device must conform to the local safety code / regulations (e.g.
within Europe, EN60204-1, Safety of machinery).

Fuse / Circuit Breaker Selection
• Suitable fuses to provide wiring protection of the input power cable should be
installed in the incoming supply line, according to the data in section Electrical
Rating Tables. The fuses must comply with any local codes or regulations in
place. In general, type gG (IEC 60269) or UL type J fuses are suitable; however,
