Commissioning
Preparation of the commissioning
7.1
The examination prior to the commissioning as well as prior to recurrent tests are
to be carried out according to national rules.
Make sure that the hydraulic accumulator is intact.
f
By means of the information given on the type cap, make sure that the
f
bladder-type accumulator corresponds to the specifications given on the
hydraulic schematic or the system's bill of materials.
Check that the fluid used in the hydraulic system corresponds to the
f
specification given in the technical data sheet and on the type cap of the
bladder-type accumulator.
Make sure that the maximum operating pressure of the hydraulic accumulator is
f
equal to or greater than the maximum operating pressure of the hydraulic circuit.
Check whether the operating temperatures are within the limits mentioned on
f
the type cap.
Cover the bladder-type accumulator with a final coating in order to ensure the
f
required corrosion protection. The product is only supplied with a primer coat.
Lay out ready the Bosch Rexroth charging and test device according to

Risk of injury and suffocation!
Risk of suffocation due to uncontrolled release of a greater volume of gas and risk
of injury due to entrained components.
Make sure that the working space is sufficiently ventilated.
f
Always use the charging and test device according to RE 50170 for the control
f
of the pre-filling pressure.
