Electrically Connecting The Axial Piston Unit - Bosch Rexroth 31 Series Instruction Manual

7.4.10 Electrically connecting the axial piston unit

Short circuit due to penetrating hydraulic fluid!
Fluid can penetrate the product and cause a short circuit!
▶
The machine/system manufacturer is responsible for the layout of the electric
control.
Electrically controlled axial piston units must be connected in accordance with the
electrical circuit diagram for the machine/system.
For axial piston units with electrical control and/or mounted sensors, please comply
with the details given in data sheet 92701, 92711 and 92709 e.g.:
• Permissible voltage range
• Permissible current
• Correct pin assignment
• Recommended electrical control units
Exact details on the connector, type of protection and matching mating connector
can also be found in data sheets 92701 and 92711. The mating connector is not
included in the scope of delivery.

Changing If necessary, you can change the position of the connector by turning the solenoid
connector position
body. This is independent of the connector version.
CAUTIOn! Hot surfaces on the solenoid!
Risk of burning!

Do not install axial piston units with electric components (e.g. electric controls,
sensors) in a reservoir below the fluid level (inside-reservoir installation).
Switch off the power supply to the relevant system component.
Electrically connect the axial piston unit (12 or 24 V). Before connecting, check
that the connector, including all seals, is intact.
Allow the solenoid to cool down sufficiently before touching it.
Wear heat-resistant protective clothing, e.g. gloves.
Loosen the mounting nut (1) of the solenoid. To do this, turn the mounting nut
(1) one turn counter-clockwise.
Turn the solenoid body (2) to the desired orientation.
Re-tighten the mounting nut. Tightening torque of the mounting nut: 5 + 1 Nm.
