Basically the HYDROVAR must be disconnected from the power supply before any work can
be carried out in the electrical or mechanical part of the system.
Installation, maintenance and repair work may only be carried out by trained, skilled and
qualified personnel.
Unauthorized modifications or changes to the system make all guarantees null and void.
During operation, the motor can be stopped by open a digital input or manually operated,
whereby the HYDROVAR and the motor remain under voltage. For safety reasons, the
HYDROVAR has to be disconnected from the power supply when carrying out work on the
machinery.
When the HYDROVAR is connected to power supply, the components of the
power unit as well as certain components of the master control unit are also
connected to the power supply.
Touching these components seriously endangers life!
Before removing the HYDROVAR cover the system must be disconnected from
the power supply. After switching off the power supply wait
at least 5 minutes before starting work on or in the HYDROVAR (the
capacitors in the intermediate circuit are discharged by the installed discharge
resistors first).
Voltages of up to 800 volts are possible (if there are faults it can be higher)
