Bosch rexroth 12 Series - Electrically Connecting the Axial Piston Unit

RE 92802-01-B/2023-03-27, BoschRexrothAG
Installation | A15VSO/A15VLO series 12 41/60
To connect the axial piston unit to the hydraulic system:
1� Remove the protective plugs and/or threaded plugs from the ports where the
connections should be made according to the hydraulic circuit diagram.
2� Make sure the sealing surfaces of the hydraulic ports and functional surfaces
are not damaged.
3� Use only clean hydraulic lines or ush them before installation.
(Observe chapter 7.5 "Performing ushing cycle" on page 42 when you ush
the hydraulic system.)
4� Connect the lines in accordance with the installation drawing and the machine
or system circuit diagram. Check that all ports are connected or plugged with
threaded plugs. For inside-reservoir installation, the housing of the axial piston
unit must be lled before tting the lines and lling the reservoir with
hydraulic uid.
5� Properly tighten the ttings (observe tightening torques!). Mark all properly
tightened ttings, e.g.with apermanent marker.
6� Check all pipes and hose lines and every combination of connecting pieces,
couplings or connecting points with hoses or pipes to ensure they are in safe
working condition.

NOTICE
Short circuit due to penetrating hydraulic uid!
Fluid can penetrate the product and cause ashort circuit!
▶ Do not install axial piston units with electric components (e.g.electric controls,
sensors) in areservoir below the uid level (inside-reservoir installation)
unless they have been explicitly released for use under hydraulic uid
(see also chapter 7.3.2 "Inside-reservoir installation" on page 29).
The machine/system manufacturer is responsible for electric control layout.
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, observe the
parameters in data sheet 92802, 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 sheet 92802. The mating connector is not included in the
scope of delivery.
1� Switch off the power supply to the relevant machine/system component.
2� Electrically connect the axial piston unit (12 or 24 V). Before establishing the
connection, check whether the connector protective covers have been removed
and the connector and all seals are intact.
