Safety Instructions
ACS/ACC/ACP 604/607 AC Drives ACx = ACS/ACC/ACP v
compatible with this kind of operation, or dangerous situations can be
caused by such action.
Supply Connections
ACx 607 units include a door interlocked fused disconnect. This switch
does not switch off the power from the EMC Line Filter of ACS/ACC
607-0400-3, -0490-3/5/6, -0610-3/5/6 and -0760-5/6 units. For ACS/
ACC 607-0400-3, -0490-3/5/6, -0610-3/5/6 and -0760-5/6 units with
EMC Line Filter, and for the ACx 604 module an input power
disconnecting means must be installed between the ac power source
and the ac drive. The disconnecting means must conform to applicable
safety regulations. The disconnecting means must be locked to the
open position during installation and maintenance work.
If an ACx 607 with the integrated EMC filter (code 0 or 3 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.
Ground Fault
Protective Function
The ACx 600 (with Standard and Motion Control Application Programs)
is equipped with an internal ground fault protective function to protect
the unit against ground faults in the drive, the motor and the motor
cable. This is not a personal safety or a fire protection feature. The
earth fault protective function of the ACS/ACP 600 can be disabled by
Parameter 30.17 (ACC: 30.11).
The internal earth fault protective function is not in use in the 12-pulse
supplied units. For ACS 62x units, refer to
ACS 600 Power Extension
Range Supplement
or
ACS 600 Converter Module Installation in User-
defined Cabinet
.
The EMC filter of the ACx 600 includes capacitors connected between
the power circuit and the chassis. These capacitors increase the
ground leakage current from the AC line through the ground (PE)
connection and may cause some ground fault current circuit breakers
to trip.
Emergency Stop
Devices
Emergency stop devices must be installed at each operator control
station and at other operating stations where emergency stop may be
required. Pressing the key on the Control Panel of ACx 600 does
not generate an emergency stop of the motor or separate the drive
from dangerous potential. Line Contactor and Emergency Stop Switch
are factory installed as an option for ACx 607.
