Safety instructions
• The suggested circuits do not imply any technical liability for
the system on the part of Rexroth.
• To switch off the system in emergencies, the power supply
to the electronics must be disconnected by an emergency
off switch. The emergency off switch must be installed in an
easily accessible position for the operator. Safe braking must
be ensured when the emergency off function is activated.
• The vehicle must be equipped with suffi ciently dimensioned,
separate mechanical service brake and parking brake.
• Lines to the electronics must not be routed close to other
power conducting lines in the machine or vehicle.
• Radio equipment and mobile telephones must not be used
inside the driver’s cab without a suitable outside antenna
and nowhere near the control electronics. A suffi ciently large
distance to radio systems must be maintained.
• All connectors must be unplugged from the electronics dur-
ing electrical welding operations.
• The electronics may only be tested with the proportional
solenoids connected.
• The proportional solenoids must not be connected to spark
suppression diodes.
On/off solenoids at the outputs of the RC electronics do not
need to be connected to spark suppression diodes.
Other inductive consumers that are in the system but not
connected to the RC must be connected to spark suppres-
sion diodes.
• In order to preserve the warranty, any installation or replace-
ment of the RC software (fl ash EPROM) must be performed
by Rexroth staff.
• Cables/wires must be sealed individually to prevent water
from entering the unit.
• Dangerous malfunctions may result if the control electronics
are opened or modifi ed or the wiring repaired without autho-
rization.
• A risk analysis according to IEC 61508 is to be performed
for the travel drive. For classifi cations greater than "SIL a",
please consult Rexroth.
• Please observe operating instructions RE 95320-B (DRCA,
DRCB, DRCC), RE 95321-B (DRCD) and RE 95322-B
(DRCE).
