2.6 Product-specific safety instructions
The following safety instructions apply to chapters 6 to 14.
Explosion hazard due to explosive atmosphere during mounting and demounting!
During mounting and demounting work, there may be no explosive atmosphere.
When working on the valve, this condition could trigger an ignition which may lead
to an explosion.
▶
Before working with the valve, ensure that no explosive atmosphere may occur
during the work.
Easily inflammable hydraulic fluid!
In connection with an explosive atmosphere or other heat sources, leaking
hydraulic fluid mist due to defective or incompletely installed valves and their
connections may lead to explosions.
▶
Only use the valve in the intended explosion protection area.
▶
The ignition temperature of the hydraulic fluid used must be 50 K higher than
the maximum surface temperature.
Exceedance of the maximum temperatures!
Use of the valve outside the approved temperature ranges may lead to malfunction
such as overheating of the valve solenoid. This means that the explosion protection
is no longer ensured.
▶
Only use the valve within the intended environmental and hydraulic fluid
temperature range.
Hot surface at the valve solenoid!
Risk of burning!
▶
Provide for a suitable touch guard.
▶
During operation, only touch the valve solenoid using heat-protective gloves.
Allow the valve solenoid to cool down to room temperature before touching it
directly with your hands during maintenance work.
Pressurized system parts and leaking hydraulic fluid!
When working on hydraulic systems with stored pressure energy (accumulators
or cylinders working under gravity), the valve may even be pressurized after the
pressure supply has been switched off. During mounting and demounting work,
the valve or parts may fly around and cause personal injuries and/or damage to
property. There is moreover the danger of serious injury caused by a powerful
leaking hydraulic fluid jet.
▶
Before working at the valve, ensure that the hydraulic system is depressurized
and the electrical control is de-energized.
▶
Completely unload the pressure at machines and systems before working at the
valve.
