Electrically Connecting The Axial Piston Unit - Bosch Rexroth A10VSNO Instruction Manual

40/60 Installation
Procedure
Bosch Rexroth AG, A10VO, A10VSO, A10VSNO Series 32, RE 92714-01-B/04.2018
To connect the axial piston unit to the hydraulic system:
1. Remove the protective plugs 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 flush them before installation. (Observe chapter
7.5 "Performing flushing cycle" on page 41 when you flush out the entire
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. With inside-reservoir installation, the housing of the axial piston
unit must be filled before fitting the lines and filling the reservoir with hydraulic
fluid.
5. Tighten the fittings correctly (observe tightening torques!). Mark all correctly
tightened fittings, 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.

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!
▶ Do not install axial piston units with electric components (e.g., electric controls,
sensors) in a reservoir below the fluid level (inside-reservoir installation).
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 92705, 92714, 92740 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 sheet 92705, 92714 and 92740. The mating connector is
not included in the scope of delivery.
1. Switch off the power supply to the relevant system component.
2. Electrically connect the axial piston unit (12 or 24 V). Before connecting, check
that the connector, including all seals, is intact.
