7 - MAINTENANCE
• All work relating to installation, commissioning
and maintenance must be carried out by
experienced, qualified personnel.
• When a trip detected by the drive causes it to
switch off, fatal residual voltages remain at the output
terminals and in the drive.
• Before carrying out any work, disconnect and
lock the drive power supply.
• Switch off the drive and external control circuits
before working on the control cables (the external
control circuits can still retain a considerable amount of
voltage).
• All protective covers must remain in place
during tests.
• Before performing high voltage tests or voltage
withstand tests on the motor, switch off the drive and
disconnect the motor.
• After working on the motor, check that the phase
order is correct when re-connecting the motor cables.
• When the drive controls a permanent magnet
motor, only one motor can be connected to the drive
output. It is advisable to install a safety switch between
the permanent magnet synchronous motor and the
drive output. This breaker isolates the motor during
maintenance work on the drive.
There are very few maintenance and repair operations to be
performed by the user on POWERDRIVE FX drives. Regular
servicing operations are described below.
7.1 - Servicing
Printed circuits and the drive components do not normally
require any maintenance. Contact your vendor or the
nearest approved repair company in the event of a problem.
CAUTION:
Do not dismantle the printed circuits while the drive
is still under warranty, as this would then immediately
become null and void.
Do not touch the integrated circuits or the microprocessor
either with your fingers or with materials which are charged
or live. Earth yourself, as well as the workbench or the
soldering iron, when performing any work on the circuits.
From time to time, with the drive powered down, check that
the power connections are correctly tightened. The door
filters must be checked and changed regulary depending on
their state.
7.2 - Storage
If the drive has been stored for more than 3 years, it is
essential to switch on the drive for 24 hours, and repeat this
operation every 6 months.
7.3 - Exchanging products
CAUTION:
Products must be returned in their original packaging
or, if thius is not possible, in similar packaging, to
prevent their being damaged. Otherwise, replacement
under warranty could be refused.
