1.2 General safety precautions
 WARNING
Improper use of the unit can result in
serious or even fatal injuries!
These operating instructions
 must have been read completely and
understood before beginning any work with
or at the pump-motor unit,
 must be strictly observed,
 must be available at the operating location
of the pump-motor unit.
 WARNING
Improper use of the unit can result in
serious or even fatal injuries!
Only operate the pump-motor unit
 for the purposes indicated under "Intended
Use"!
 with the fluids indicated under 'Intended
Use'!
 with the values indicated under 'Technical
Data'!
 WARNING
Improper use of the unit can result in
serious or even fatal injuries!
All work on and with the pump-motor unit
(transport, installation, operation, shut-down,
maintenance, disposal) may only be carried
out by trained, reliable expert personnel!
 WARNING
When working on the unit, there is a danger
of injury, e.g. in the form of cuts/cutting off,
crushing and burns!
During all work on and with the pump-motor
unit (transport, installation, operation, shut-
down, maintenance, disposal) wear personal
safety equipment (safety helmet, protective
gloves, safety shoes)
!
 WARNING
Hair and clothing can be pulled into the unit
or caught and wound up moving parts!
Do not wear long, loose hair or wide, loose
clothes! Use a hair net!
 DANGER
Electrical danger!
Before beginning work on the unit or system,
the following measures must be carried out:
 Deenergize.
 Secure against being switched on again.
 Determine whether deenergized.
 Ground and short-circuit.
 Cover or block off adjacent energized parts.
 DANGER
Electrical danger!
Work on electrical installations may be carried
out by trained and authorized electricians only!
 DANGER
Electrical danger!
Replace loose connections, singed or burned
cables immediately!
 DANGER
Electrical danger!
Do not open the motor terminal box unless
absence of electricity has been ensured!
 DANGER
Electrical danger!
Depending on the charging state of the
capacitors, a residual voltage may be present
on the terminals in the terminal box.
After opening the terminal box cover, it must
be ensured that the capacitors are completely
deenergized:
 Measure the voltage at the corresponding
jumpers (see the circuit diagram in the
terminal box).
 Dissipate the residual voltage with suitable
means if necessary.
The capacitors must be completely
deenergized.
 WARNING
Danger due to gauge pressure and vacuum!
Danger due to escaping fluid!
Before beginning work on the unit or system:
 Interrupt supply of operating liquid.
 Bleed lines and vacuum pump/compressor
(depressurize).
