52 Operation principle and hardware description
• a contactor controlled by the drive, and
• terminal block X601 for customer connections.
The number of connections must be specified when ordering. The maximum number of
connections available depends on the current requirement. The lower current ratings allow
up to four fan connections (eg. option +4M602), while the highest current rating only allows
one (eg. +M610). For more information, refer to ACS880-X7 single drives ordering information
(3AXD10000052815, available on request).

Description

The output for the auxiliary fan is wired from the 3-phase supply voltage to terminal block
X601 through a motor starter switch and a contactor. The contactor is operated by the drive.
The 230 V AC control circuit is wired through a jumper on the terminal block; the jumper
can be replaced by an external control circuit.
The starter switch has an adjustable trip current limit, and can be opened to permanently
switch the fan off.
The statuses of both the starter switch and the fan contactor are wired to the terminal block.
See the circuit diagrams delivered with the drive for the actual wiring.
