Supply Connections - ABB ACS 600 Hardware Manual

Supply Connections

601/604/607 US Supplement
WARNING! There are several automatic reset functions in the ACx
600. If selected, they reset the unit and resume operation after a fault.
These functions should not be selected if other equipment is not
compatible with this kind of operation, or dangerous situations can be
caused by such action.
The ACx 601 does not include a disconnecting means. An input power
disconnecting means must be installed between the AC power source
and the ACx 601. The disconnecting means must conform to the
applicable safety regulations. The disconnecting means must be
locked in the open position during installation and maintenance work.
The motor must not be controlled with the supply disconnecting means;
instead, the and
the I/O board of the ACx 600 should be used. The maximum number of
charging cycles of the d.c. capacitors of ACx 600 (i.e. power-ups by
applying power) is five in ten minutes.
ACx 6x7 units include an on-load isolating fused disconnect with a
through the door handle. This switch does not switch off power from
the EMC Line filter of the ACx 607-0490-3/5/6, -0610-3/5/6 and -0760-
5/6 units. For ACx6x7-0490-3/5/6, -0610-3/5/6, and -0760-5/6 units
with EMC filters and for the ACx 604 module, a supply disconnecting
device must be installed in the supply, by which the electrical parts of
the unit can be separated from the power network during installation
and maintenance work. The supply disconnecting device must be
locked to the open position during installation and maintenance work.
WARNING! Never connect the line power to the ACx 600 output
terminals U , V , or W
2 2 2
interlocked switches or contactors should be employed. Line voltage
applied to the output may result in permanent damage to the unit.
Operation outside the nominal input line voltage range should not be
attempted, as overvoltages can result in permanent damage to the
ACx 600.
If an ACx 601 with the integrated EMC filter (code 0 in the type code for
EMC Filters) is connected to an ungrounded power system or high
resistance grounded power system (over 30 Ohms), the power line will
be connected to ground potential through the EMC filter capacitors of
the ACx 601. This may cause danger or damage the unit. Disconnect
the EMC filter capacitors before connecting the ACx 601 to an
ungrounded power system. For detailed instructions on how to do this,
please contact your local ABB distributor.
It is not allowed to install an ACx6x4/6x7 with EMC filter options to
keys of the Control Panel or commands via
. If frequent bypassing is required, mechanically
