Bosch Rexroth 10 Series Instruction Manual page 35

Axial piston units with electric components (e.g. electric controls, sensors)
must not be installed in a reservoir below the fluid level.
If inside-reservoir installation is intended nevertheless, the IP protection
class and the medium compatibility of the electric components used must be
checked in the individual case. Please consult your proper contact person at
Bosch Rexroth to commission an examination of the medium compatibility.
Recommended installation position: 4.
Because complete air bleeding and filling is not possible in installation positions
5, the pump must be air bled and filled in a horizontal position prior to
installation.
With small tank sizes or unfavorable suction conditions, we recommend fitting
a suction pipe to suction port S (A/B) and fitting a pipe to drain port L or L
In this case, the other drain port must be plugged. The housing of the
axial piston unit must be filled before fitting the piping and filling the reservoir
with hydraulic fluid. To prevent draining of the housing, the reservoir has to be
filled with hydraulic fluid as soon as possible.
