Product-Specific Safety Instructions - Bosch Rexroth 4WRPEH6 3X Operating Instructions Manual

2.6 Product-specific safety instructions

Non-compliance with functional safety!
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.
▶ During set-up of your circuit, observe the applicable standards on functional
safety, e.g. EN ISO 13849-1.
Dangerous movement!
It is not allowed for persons to stay within the range of motion of machines
and machine parts. The following are examples of possible measures against
unintended access of persons:
• Protective fences
• Protective grids
• Protective covers
• Light barrier
▶ If persons must access the danger zone during active control, monitoring
or measures must be provided for personal safety which are superior to the
system. These measures must be provided according to the specific data
of the system and on the basis of the risk and error analysis of the system
manufacturer/user. In this connection, the safety provisions applied for the
system must be taken into account.
▶ In case of faults impairing the safety and changes in the operating behavior,
shut down the valve immediately and report the faults to the responsible
personnel.
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, valves and
related components may fly around and cause personal injuries and/or damage
to property. There is moreover the danger of serious 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
hydraulic products.
Electrostatic processes!
Valve electronics are sensitive to electrostatic charging and can be damaged.
This can lead to uncontrolled reactions at the valve.
▶ During assembly and troubleshooting of valves with integrated electronics,
observe applicable ESD regulations.
▶ Do not touch any electric pins. Do not remove the electronics housing.
