16/104 A4... with HS5E(V)(L) control system Series 1x and 30 | Safety instructions
Bosch Rexroth AG, RE 92076-01-B/2021-04-22
Hot surfaces on the axial piston unit and HS5E(V)(L) control system!
Risk of getting burnt!
▶ Allow the axial piston unit and the HS5E(V)(L) control system to cool down
sufficiently before touching them.
▶ Wear heat-resistant, protective clothing, e.g. gloves.
Improper cable and line routing!
Risk of stumbling and property damage! Due to incorrect routing of lines and
cables, both a risk of stumbling as well as damage to parts and components can
occur, e.g. due to lines and connectors being torn off.
▶ Always install cables and lines in a way that nobody can fall over them, that
they are not bend or twisted, do not chafe on edges and are not guided through
ducts with sharp edges without sufficient protection.
Contact with hydraulic fluid!
Risk of adverse health effects, e.g. eye injury, skin irritation, toxication from
inhalation!
▶ Avoid any contact with hydraulic fluids.
▶ When handling hydraulic fluids, the safety instructions of the lubricant
manufacturer need to be observed at all times.
▶ Use your personal protective equipment (e.g. safety goggles, safety gloves,
suitable working clothes, safety shoes).
▶ Immediately seek medical attention, however, if hydraulic fluid gets into your
eyes or blood circuit or if you swallow it accidentally.
Danger from improper handling!
Slip hazard! Risk of slipping on wet surfaces when climbing on the axial piston unit.
▶ Never grab or climb onto the axial piston unit.
▶ Check how to safely get on top of the machine/system.
Missing potential equalization on the hydraulic unit!
Uncontrolled function of the axial piston unit.
▶ Missing or incorrect potential equalization on the hydraulic unit can lead to
its functions being uncontrolled. Depending on the application, this can lead
to hazards to persons. This means that you must ensure proper potential
equalization by means of the existing pin assignment on the connector side.
Interference in case of energy fluctuations and/or energy failure with HS5E, open
circuit (A4VSO, A4VBO)!
Uncontrolled movements in the system:
▶ In case of energy fluctuations and/or energy failure, the axial piston unit will
return into the basic position V
Limiting the minimum displacement can cause torque to be generated in the
application.
Check whether additional measures are necessary on your machine for the
application in order to guarantee that the torque is switched off. If necessary,
make sure these are appropriately implemented.
CAUTION
if the control pressure supply is sufficient.
