Safety Instructions
6 ACS 600 MultiDrive
The supply section can be equipped with an earthing switch as an
option. It is used to earth the AC busbars for safety reasons when work
is being done on the system. The device is mechanically or electrically
interlocked with the main switch.
WARNING! Each drive section can be equipped with an optional
manually operated switch fuse for electrical disconnection. During
maintenance work in the drive section or on the motor or the motor
cable, the switch fuses of all parallel connected drive sections must be
locked to the open position, or the DC fuses of all parallel connected
drive sections must be removed if the switch fuses are not installed.
Opening the disconnecting device does not remove all control
voltages. Before starting work, check with the circuit diagrams which
circuits remain live after opening the disconnecting device.
Note:
Voltages from external control circuits may be present.
Earth Fault Protective
Function
The ACx 600 is equipped with an internal earth fault protective function
to protect the unit against earth faults in the inverter, the motor and the
motor cable. This is not a personal safety or a fire protection feature.
The internal earth fault protective function is not applicable in the
parallel connected inverters. For more information on the earth fault
parameter settings, see the appropriate firmware manual.
The supply of the ACx 600 can be equipped with an optional earth fault
protective function, refer to
Supply Section Manuals .
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 ACS 600
MultiDrive does not generate an emergency stop of the motor or
separate the drive from dangerous potential.
An emergency stop function has been provided (optional) in the
ACx 600 to stop and switch off the whole drive. The available modes
are: Immediate Removal of Power and Controlled Emergency Stop
(with thyristor supply only). The emergency stop function must not be
used as the normal mode of stopping the drive.
The emergency stop function complies to the principles of the
standards listed below.
