2.6 Product-specific safety instructions
The following safety instructions apply to chapters 6 to 14.
Explosion hazard due to ignitable atmosphere during all work on the valve!
During all work on the valve (assembly, disassembly etc.), an explosive atmosphere
must be avoided! 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 fluids
(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.
Exceeding the maximum temperatures!
The use of the valve outside the approved temperature ranges may lead to
functional failures like overheating of the valve solenoid. Explosion protection is
therefore no longer ensured.
▶
Only use the valve within the intended environmental and hydraulic fluid
temperature range.
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 be
ejected and cause personal injury and/or damage to property. Furthermore, there is
the danger of severe injury caused by a powerful leaking hydraulic fluid jet.
▶
Ensure before working at the hydraulic product that the hydraulic system is
depressurized and the electrical control de-energized.
▶
Completely unload the pressure at machines and systems before working at the
valve.
