WARNING!
When the control terminals of two or more drive
units are connected in parallel, the auxiliary voltage for these
control connections must be taken from a single source which
can either be one of the units or an external supply.
WARNING!
If a drive whose EMC filter is not disconnected is
installed on an IT system [an ungrounded power system or a
high resistance-grounded (over 30 ohms) power system], the
system will be connected to earth potential through the EMC
filter capacitors of the drive. This may cause danger or damage
the drive.
If a drive whose EMC filter is not disconnected is installed on a
corner grounded TN system, the drive will be damaged.
Note:
When the EMC filter is disconnected, the drive is not EMC
compatible.
For disconnecting the EMC filter, see pages
(frame sizes
R1…R4) and
(frame sizes R5…R6) in chapter
.
WARNING!
The ACH550 is not a field repairable unit. Never
attempt to repair a malfunctioning unit; contact the factory or
your local Authorized Service Center for replacement.
WARNING!
The ACH550 will start up automatically after an
input voltage interruption if the external run command is on.
WARNING!
The heat sink may reach a high temperature. See
