Commissioning
Safe handling of pressure tapping points
8.1.3
When setting pressure valves, the respective pressures must be displayed. This
can be done by using fixed installed pressure gauges, digital pressure displays or
by connecting external measuring equipment. For this purpose, measuring cou-
plings have been installed within the drive module. As the measuring points can be
operated while under pressure, extreme caution is required!
If the scope of delivery includes a measuring device that is connected to both mea-
suring hose and coupling, the connection may only be opened on the coupling side.
The following diagram (see Fig. 11) shows the position for safe separation of the
measuring equipment from the pressurized measuring coupling of the drive module.

Accumulator
8.1.4
If the drive modules includes accumulators, the instructions applicable at the
place of installation are to be complied with before commissioning as well as dur-
ing operation. Operating Instructions are supplied with each accumulator.
You should ensure that these documents are kept together with the accumula-
f
tor. Experts will need these for subsequent inspections.
On the hydraulic fluid side, the hydraulic system must be sealed tightly, bled
f
(see Chapter 8.1.7 "Bleeding the complete hydraulic system of the machine")
and depressurized.
Fill the accumulator according to the information in the circuit diagram to the
f
prescribed preset gas pressure.
The filling and measuring procedures are undertaken using testing and filling
f
equipment (in this connection see "Product-specific operating instructions" for
this device).
Affix a label to the accumulator specifying the accumulator filling pressure and
note this value in the circuit diagram. This will enable you to perform a
comparative control at a later date.
