NOTICE
Different pressure
Observe the different pressure for the nozzle changer on the D4/D4i machine (5.1 +/- 0.1 bar),
which is significantly higher than that for the nozzle changer of the D1/D2/D1i/D2i machines.

4.1.1.3 Preparing the power supply unit for measurement
Preparing the power supply unit for measurement
The power supply unit and main switch are located in the machine base. In front of the unit there is a set
of safety doors which can be opened with the double-bit key.
The unit is fixed to the machine base using an M8 hexagon socket-head screw.
To measure the power supply, proceed as follows:
► Switch the placement system off at the main switch.
► Open the safety doors with the double-bit key.
► Loosen the M8 lock screw, fastening the underside of the unit at the front (see fig).
WARNING
Nonobservance of these safety instructions may cause injury to personnel and damage to the
machine!
The service work described in this manual may only be performed by specially trained service
technicians, with appropriate qualifications and expertise.
► Please observe the safety instructions in the Operating Manual for all service work!
DANGER
The machine is supplied with 3 x 400 V~ (or 3 x 204 V~ / 3 x 230 V~ / 3 x 380 V~ / 3 x 415 V~)
± 5 %, 50/60 Hz mains voltage.
Consequently, parts of the system carry potentially lethal voltages, even when it is switched off
at the main switch.
Incorrect handling of the machine can therefore result in death, severe injury or considerable
damage to equipment.
Measurements and repairs must always be carried out by appropriately qualified personnel.
► Always follow the safety instructions in chapter 2 of this manual.
► Always follow the applicable accident prevention and VDE regulations (particularly DIN EN
60 204 part 1) or the regulations specific to your country.
