6 ACS550-02/U2 User’s Manual
Safety
WARNING! Disconnect the EMC filter (frame size R7) and the varistor network
(frame sizes R7 and R8) when installing the drive on an IT system [an ungrounded
power system or a high resistance-grounded (over 30 ohm) power system],
otherwise the system will be connected to earth potential through the EMC filter
capacitors or varistor network. This may cause danger or damage the drive.
Disconnect the EMC filter (frame size R7) and the varistor network (frame sizes R7
and R8) when installing the drive on a corner grounded TN system, otherwise the
drive will be damaged.
WARNING! Do not control the motor with the disconnecting device (disconnecting
means); instead, use the control panel start and stop keys and , or
commands via the I/O board of the drive. The maximum allowed number of charging
cycles of the DC capacitors (i.e. power-ups by applying power) is five in ten minutes.
WARNING! The ACS550-02/U2 is a field repairable drive. In case of service or
repair of malfunctioning drive, contact your local Authorized Service Centre for
service.
WARNING! The ACS550 will start up automatically after an input voltage interruption
if the external run command is on.
WARNING! The heat sink will reach a high temperature. See chapter Technical data
on page 293.
