7.4.9 Electrically connecting the axial piston unit
NOTICE
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 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information in datasheet92035, 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92035. The mating connector is not included in the
scope of delivery.
1. Switch off the power supply to the relevant machine/system part.
2. Electrically connect the axial piston unit (12 or 24 V). Before connecting,
checkwhether the connector protective covers (3) are off (see Fig. 12
"Removing transportprotection" on page 38), and the connector and all seals
are intact.
7.5 Performing flushing cycle
In order to remove foreign particles from the system, BoschRexroth recommends
a flushing cycle for the hydraulic system before the first commissioning. To avoid
internal contamination, do not include the axial piston unit in the flushing cycle.
Use an additional flushing unit to perform the flushing cycle. Follow the
instructions of the flushing unit's manufacturer for the exact procedure during the
flushing cycle.
