•
Before turning on the controller for the first
time and after completion of the wiring, check
whether all motor connections are tight on the
controller and the motor side and whether the
motor is correctly wired in star or delta
configuration. Loose motor connections
usually damage the inverter.
•
If several devices are to be connected, the
voltage and power specifications under
"Control voltage / external supply 2" in the
technical data must be observed (see page
•
If the 24 V controller voltage is short circuited
or overloaded, the switching power supply will
not start up even though the intermediate
circuit capacitors are charged. The displays
remain turned off. The power supply can only
be restarted after eliminating the short circuit
or the overload condition.
•
To fulfill the conditions of the EMC Directives,
only shielded and separate motor conductors
must be used, with the shield connected on
both ends (motor and controller side) and
without any additional connections in the line.
Maximum cable length: 30 m
•
Fast running plastic foil doors may produce
very high electrostatic charges. A discharge
of these voltages may damage the controller.
Therefore suitable measures must be taken
to prevent electrostatic discharge.
•
Turning on or operating the controller in the
presence of condensation is not permitted. It
can lead to the damage of the controller.
•
Before turning on the controller supply for the
first time, ensure that the detector/sensor
cards (plug-in modules) have been inserted in
the correct locations. Incorrect insertion of the
cards can result in damage to the controller,
likewise the installation of non-approved third-
party equipment.
•
First connect the cables to the connection
terminals and then attach them to the
connectors! Only thus is it possible to ensure
a safe contact of the connection terminals to
the plug connectors.
