2.6 Product-specific safety instructions

The following safety instructions apply to chapters 6 to 14.
Pressurized system parts and leaking hydraulic fluid!
When working at hydraulic systems with stored pressure energy (accumulator or
cylinders working under gravity), valves may even be pressurized after the pressure
supply has been switched off. During assembly and disassembly works, the
safety valve or parts may fly around and cause personal injuries and/or damage
to property. There is more over the danger of serious injury caused by a powerful
leaking hydraulic fluid jet.
Ensure before working at the safety valve that the hydraulic system is
f
depressurized and the electrical control de-energized.
Completely unload the pressure at machines and systems before working at
f
valves.
Non-compliance with functional safety!
Hydraulic valves control 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.
When setting up your circuit, observe functional safety e.g. according to
f
EN ISO 13849.
Faulty mounting!
Mounting of the safety valve with valve mounting screws of reduced stability,
insufficient mounting at blocks and plates with insufficient stability may cause the
safety valve to become loose and fall down. Consequently, hydraulic fluid may leak
and lead to personal injuries and/or damage to property. Safety valves with high
weight may bruise or kill persons. Special care must be taken with safety valves
with suspended installation.
Completely assemble the safety valve according to the assembly specifications
f
by means of suitable assembly aids.
Only assemble the safety valve at valve installation surfaces suitable for the
f
weight of the valves.
Comply with tightening torques and screw stabilities.
f
Easily inflammable hydraulic fluid!
In connection with fire or other heat sources, leaking hydraulic fluid mist may lead
to fire or explosions due to defective or incompletely mounted safety valves and
their connections.
Do not use the safety valve in areas with open fire and only at a sufficient
f
distance to hot heat sources.
