42/60 Installation
Bosch Rexroth AG, RE 92100-01-B/09.2012 Series 10, 11 and 30,
1. Switch off power supply to the relevant system component.
2. Electrically connect the axial piston unit (12 or 24V). Before connecting, check
that the connector including all seals are intact.
With EP control, you can change the connector orientation by turning the solenoid
housing. For all other electrical control and regulation devices and displacement
pick-ups, a change of position is only permissible after consulting your responsible
Bosch Rexroth Service partner. For the address, please refer to chapter10.5 "Spare
parts" on page50.
To do this, proceed as follows:
1. Loosen the mounting nut (1) of the solenoid. To do this, turn the mounting nut
(1) one turn counterclockwise.
2. Turn the solenoid body (2) to the desired position.
3. Retighten the mounting nut. Tightening torque of the mounting nut: 5+1 Nm.
On axial piston units with a Hirschmann connector according to DIN EN 175 301-803-A/
ISO 4400, the following tightening torques apply when securing line connectors:
t Mounting bolt M3 (1): 0.5
t Union nut M16x1.5(2): 1.5–2.5Nm

7.5 Peforming flushing cycle
In order to remove foreign particles from the system, Bosch Rexroth recommends a
flushing cycle for the entire system before the first commissioning. To avoid internal
contamination, the axial piston unit must not be included in the flushing cycle.
The flushing cycle must be performed with an additional flushing unit. Follow the
instructions of the flushing unit's manufacturer for the exact procedure during the
flushing cycle.
