RE 62272-B/03.19, Manifold block type AGEV1-48404-AA/HM/L01H01-XC,
Bosch Rexroth AG
WARNING
System parts under pressure and ejecting hydraulic fluid!
When working on hydraulic systems with stored pressure energy (accumulator or
cylinders working under gravity), hydraulic blocks may even be pressurized after the
pressure supply has been switched off. During mounting and demounting, built-on
or attached components may be hurled around and cause personal injuries and/
or damage to property. There is moreover the risk of serious injury caused by a
powerful, ejecting hydraulic fluid jet.
▶
Before working on the hydraulic product ensure that the hydraulic system is
depressurized and the electrical control de-energized.
▶
Completely unload the pressure of machines and systems before working on
hydraulic products.
▶
Secure the system against restarting.
High pressure!
Risk of injury caused by oil jet and parts ejected under pressure due to rupture of
the a system component.
▶
Shut the system down when an oil jet is ejecting and replace damaged
components.
▶
Limit the pressure in the system by means of an overpressure element.
▶
Direct the tank line freely to the tank without narrowing in the cross-section and
without any shut-off feature.
▶
Use hydraulic lines and connections in accordance with the maximum operating
pressure.
▶
Never disconnect, open or cut pressurized lines or remove pressurized
components!
▶
Switch the system off before mounting or carrying out any other work on
manifolds.
Leakage in case of incorrect operating temperatures!
Using manifolds outside the temperatures they are designed for may lead to
permanent leakage of the hydraulic valves. Thus, hydraulic fluid in the form of an
ejecting hydraulic fluid jet may injure persons, lead to damage to property and
endanger the environment.
▶
Use manifolds only at the ambient and fluid temperatures specified for them.
▶
In case of leakage, immediately exchange damaged seal rings or the hydraulic
valve.
Explosion hazard due to lack of equipotential bonding!
Electrostatic processes, an incorrect earthing concept or a lack of equipotential
bonding may lead to an explosion. Apart from this, malfunctions or uncontrolled
movements at the machine may be caused!
▶
Provide for correct earthing and provide for proper equipotential bonding. The
connection point for equipotential bonding is marked on the assembly drawing
of the manifold.
▶
The console on which the manifold is mounted must be included in equipotential
bonding according to EN 60079-14 and IEC 60364-4-41.
