Bosch Rexroth 4WRPEH6 3X Operating Instructions Manual page 29

Improper installation of connectors and cable routing!
Incorrectly secured M12 connectors and cables routed not in compliance with the
assembly instructions may become loose during operation and cause damage.
This can lead to loss of communication with the valve or failure of valve functions.
▶ Lay cables and lines so that they cannot be damaged and no one can trip
over them.
▶ Tighten M12 connectors to 1 Nm with a manual torque wrench.
▶ Use self-locking M12 cables.
▶ Make sure that cables are secured without radial forces.
▶ Secure M12 cables after 20 to 30 cm and make sure that there is no relative
motion between the fixture and the valve. Before the fixation point, there must
not be any cable loops.
▶ Observe any general information provided by the cable manufacturers for laying
of cables.
Missing seals and caps!
Risk of short-circuit! Fluids may enter the valve and cause a short-circuit.
▶ Before commissioning, ensure that all seals and caps of the plug-in connections
are leak-proof.
Incorrect connection wiring!
Risk of injury due to electric shock and malfunctions! The valve may only be
connected by or under the supervision of a specialized electrician. The lines used
have to be suitable for operating temperatures of -20 °C...+100 °C.
▶ De-energize the connection line before installation.
▶ Correctly connect the protective grounding conductor and the grounding.
▶ Ensure that there are no sharp bends in the connection line and braided wires
to avoid short-circuits and interruptions.
▶ Cable and line entry must always be assembled according to the assembly
instructions.
▶ During the assembly, ensure leak-tightness between connection line, cable and
line entry.
▶ Only use connection lines which comply with the requirements specified in the
data sheet.
Electro-magnetic processes!
Hydraulic valves with electronics components may cause interferences at other
electronics components due to electro-magnetic radiation. This can lead to
uncontrolled motion at the system.
▶ Observe the limit values for electro-magnetic radiation and shield any other
electronic components as necessary.
