To connect the axial piston unit to the hydraulic system:
1. Remove the protective plugs and threaded plugs at the ports at which the
connections are to be made according to the hydraulic schematic.
2. Make sure that the sealing surfaces of the hydraulic ports and functional surfaces
are not damaged.
3.
Use only clean hydraulic lines or flush them before installation. (Note chapter7.5
"Peforming flushing cycle" on page42 when you flush out the complete system.)
4. Connect the lines in accordance with the installation drawing and the machine
or system schematic. Check whether all ports are connected or plugged with
threaded plugs.
5. Tighten the fittings correctly (note 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
condition for safe working.
For relationship between direction of rotation and flow direction, please refer to
data sheet.
7.4.9 Electrically connecting the axial piston unit
NOTE
Short circuit in event of 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 schematic for the machine/system.
For axial piston units with electrical control and/or mounted sensors, please comply
with the details given in data sheet RE 92100 or data sheet for control (see Table 1
"Required and supplementary documentation" on page5), e.g.:
t the permissible voltage range
t the permissible current
t correct connection
t the recommended electrical control units
Exact details on the connector, type of protection and matching mating connector
can also be found in data sheet RE 92100 or data sheet for control (see Table 1
"Required and supplementary documentation" on page5). The mating connector
is not always included in the delivery contents.
