2.6 Product-specific safety instructions
The following safety instructions apply to chapters 5.1.2 to 14.
WARNING
Explosion hazard due to ignitable atmosphere during all work on the valve!
During all work on the valve (assembly, disassembly etc.), there must not
be an explosive atmosphere. Otherwise, an ignition may be triggered which may
lead to an explosion.
▶
Before working with the valve, ensure that no explosive atmosphere can occur
during the work.
Easily inflammable liquid!
In connection with an explosive atmosphere or other heat sources, the use
of liquids (e.g. hydraulic fluid, coolants etc.) may lead to explosions.
▶
Only use the valve in the intended explosion protection area.
▶
The ignition temperature of the liquid used must be 50 K higher than the
maximum surface temperature.
Hot surface at the valve!
Risk of burning!
▶
Provide for a suitable touch guard.
▶
During operation, only touch the valve using heat-protective gloves. Allow the
valve 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 at hydraulic systems with stored energy (accumulator or cylinders
working under gravity), valves may even be pressurized after switching off the
pressure supply. During assembly and disassembly works, the valve or parts may fly
around and cause personal injuries and/or damage to property. Furthermore, there
is 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.
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.
