2.6 Product-specific safety instructions
The following safety instructions apply to chapters 6 to 14.
WARNING
Explosion hazard due to explosive atmosphere during assembly!
During the assembly, an explosive atmosphere must be avoided. During work at the
valve, this condition could trigger an ignition, which may lead to an explosion.
▶
Before working with the valve, ensure that no explosive atmosphere can occur
during the work.
Easily inflammable hydraulic fluid!
In connection with an explosive atmosphere or other hot heat sources, leaking
hydraulic fluid mist due to defective or incompletely assembled 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 at least 150 °C.
Explosion hazard due to the exceedance of the maximum temperatures!
If the valve is used outside the approved temperature ranges, the explosion
protection no longer applies!
▶
Only use the valve within the intended environmental and hydraulic fluid
temperature range.
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 assembly and disassembly work,
the valve or parts may be ejected and cause personal injury and/or damage to
property. There is moreover the danger of severe 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.
Non-compliance with functional safety!
The valve controls movements in machines or systems. In case of mechanical and
electric faults, e.g. failure of the energy supply, persons may be caught by the
system, kicked away or bruised.
▶
During set-up of your circuit, observe functional safety e.g. according to
EN ISO 13849.
