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
stop switch. The emergency stop switch must be installed
in a location which is easily accessible to the operator. Safe
braking must be ensured when the emergency stop function
is activated.
• 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
during 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.
Switching solenoids at the outputs of the RC electronics
need not be connected to spark suppression diodes.
Other inductive loads that are in the system but not
connected to the RC must be connected to spark suppression
diodes.
• In order to preserve the warranty, any installation or replace-
ment of the RC software (fl ash EPROM) must be performed
by personnel from Rexroth.
• 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
authorization.
• Please observe operating instructions RE 95 350-B.
