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 flush them before installation. 
(Observe chapter 7.5 "Performing flushing cycle" on page 44 when you flush 
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.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� 

Properly tighten the fittings (observe tightening torques!). Mark all properly 
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.

For relationship between direction of rotation and flow direction, 
see data sheet 92110.

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) unless 
they have been explicitly released for use under hydraulic fluid, e.g. HS5M, 
EO2M (see also chapter 7.3.2 "Inside-reservoir installation" on page 31).

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 adjustment and/or mounted sensors, 
observe the details given in the respective data sheets of the electrical controls in 
Table 1 "Required and supplementary documentation" on page 5:

 

• Permissible voltage range

 

• Permissible current

 

• Correct pin assignment

 

• Recommended electrical control units
