connect three out of five (or six out of ten, etc.) cables to the cubicle with three modules,
the remaining two out of five (four out of ten) cables to the cubicle with two modules.
￭ Additional terminal block X504 (option +L504)
The standard terminal blocks of the drive control unit are wired to the additional terminal
block at the factory for customer control wiring. The terminals are spring loaded.
Cables accepted by the terminals:
• solid wire 0.08 to 4 mm2
• stranded wire with ferrule 0.14 to 2.5 mm2
• stranded wire without ferrule 0.08 to 2.5 mm2 (28 to 12 AWG).
Stripping length: 10 mm.
Note:
The optional modules inserted in the slots of the control unit (or optional FEA-03 extension
adapter) are not wired to the additional terminal block. The customer must connect the
optional module control wires directly to the modules.
￭ Starter for auxiliary motor fan (options +M6xx)
What the option contains
The option provides switched and protected connections for 3-phase auxiliary motor fans.
Each fan connection is equipped with
• fuses
• a manual motor starter switch with an adjustable current limit
• 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 ACS-880-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.
