2.6 Product-specific safety instructions
The following safety instructions apply to chapters 6 to 14.
Explosion hazard due to explosive atmosphere during assembly!
During assembly, there must not be an explosive atmosphere. During works at the
valve, this condition could trigger an ignition that may lead to an explosion.
▶
Ensure before working with the valve that no explosive atmosphere may occur
during the work.
Easily inflammable hydraulic fluid!
In connection with an explosive atmosphere or other warm 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 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 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.
Valve solenoid has hot surface!
Risk of burning!
▶
Provide a suitable touch guard.
▶
During operation, only touch the valve solenoid with heat-protective gloves.
Allow the valve solenoid to cool down to room temperature before touching
it directly with your hands during maintenance works.
Modifications at the gaps of the pressure-tight enclosure will create an explosion
hazard!
Explosion hazard! The terminal box with its cover and cable and line entry will
create a pressure-tight gap.
▶
To ensure explosion protection, these gaps may not be modified.
▶
The gaps must remain free of dirt and damage.
▶
The mounting screws of the cover and the cable and line entry must
be assembled as specified.
