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.
 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).
CAUTION
Incorrect connection of the motor
can lead to serious damage to
