52/72 A10FZO, A10VZO, A10FZG and A10VZG series 10 | Installation
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 7.6 "Performing flushing cycle" on page 53 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. For 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 assignment between direction of rotation and flow direction,
see data sheet 91485 and Tabelle 7 to Tabelle 9 "Flow direction" starting on
page24.

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 (see also chapter 7.3.2 "Inside-reservoir installation" on page 34).
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 91485, 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 91485. The mating connector is not included in the
scope of delivery.
