Electrically Connecting The Axial Piston Unit - Bosch Rexroth 63 Series Instruction Manual

7.4.9 Electrically connecting the axial piston unit

Short circuit in event of 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 schematic for the machine/system.
For axial piston units with electrical control and/or mounted sensors, please comply
with the details given in data sheets RE 92202 and RE 92203, e.g.:
• the permissible voltage range
• the permissible current
• correct connection
• the recommended electrical control units
Exact details on the connector, type of protection and matching mating connector
can also be found in data sheets RE 92202 and RE 92203. The mating connector is
not included in the delivery contents.

Changing connector If necessary, you can change the connector orientation by turning the solenoid
orientation
housing. This is dependent on the connector version.
To do this, proceed as follows:

Relationship between direction of rotation and flow direction:
Clockwise rotation:
Counter-clockwise rotation:
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 power supply to the relevant system component.
Electrically connect the axial piston unit (12 or 24V). Before connecting, check
that the connector including all seals are intact.
Loosen the mounting nut (1) of the solenoid. To do this, turn the mounting nut
(1) one turn counterclockwise.
Turn the solenoid body (2) to the desired position.
Retighten the mounting nut. Tightening torque of the mounting nut: 5+1 Nm.
