Important safety instructions

Read and follow the operating and safety instructions carefully before starting operations!
Warning that failure to observe the precaution may cause electric shock
Warning that failure to observe the precaution may cause personal injury or damage to property.
In addition to these operating instructions please pay attention to universal safety and accident prevention regulations.
Basically the HYDROVAR must be disconnected from the power supply before any work can be carried out on the electrical or mechanical
part of the system.
Installation, maintenance and repair work may be carried out only by trained, skilled and qualified personnel.
Unauthorized modification or changes to the system make all guarantees null and void.
During operation, the motor can be stopped by opening a digital input or manual operation 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 the power supply, the components of the power unit as well as certain
components of the control unit are connected directly to mains.
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 internal discharge resistors).
Voltages of up to 800 volts are possible (in case of error these also can be higher)
All work, carried out on the HYDROVAR, may only be performed by qualified and authorized staff.
Furthermore, take care not to short circuit the neighbouring components when connecting the external control wires.
All cable ends which are not in use have to be isolated.
The HYDROVAR contains electronic safety devices which switch off the control element in the event of a fault,
whereby the motor has zero current but remains energised and comes to a halt. The motor can also be halted by
mechanical blocking. If it is switched off electronically the motor is current less from the mains voltage through the
electronics of the HYDROVAR but is not potential-free in the circuit.
In addition voltage fluctuations, especially power failures can cause the system to switch itself off.
Repair of faults can cause the motor to start up again automatically!
The system may only be put into operation when it has been grounded.
In addition to that, equipotential bonding of all conductive pipes must be ensured.
Please consider local installation standards!
High voltage tests of the HYDROVAR or the motor may damage the electronic components! Hence bridge the in- and
outgoing terminals L1 - L2 - L3 / U-V-W before.
To avoid incorrect metering by capacitors incorporated in the electronic part isolate the motor from the HYDROVAR.
The operating instructions must be read, understood and followed by the operating
personnel. We point out that we accept no liability for damage and operating disorders
All modifications must be done by qualified technicians!
which are the result of non-compliance with the operating instructions.
