Tools and equipment required
▪ Digital voltmeter, class 1.5
Measurement range:
– AC voltage: 750 V
– Alternating current: 40 A
– DC voltage: 300 V
– Direct current: 30 A
– Resistance: 200 Ohm - 20 MOhm
▪ Test cable with test probes or terminals
▪ Detailed circuit diagrams for SIPLACE D1/D2 [German: 0194841-xx] [English: 0194842-xx]
▪ DIN 911 Allen key, size 6
▪ 3 mm key, double-bit, DIN 43668-J33 (00304191-xx)
Preparing the power supply unit for measurement
The power supply unit and main switch are located in the machine frame. 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 frame using an M8 hexagon socket-head screw.
To measure the power supply, proceed as follows:
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 placement system can therefore result in death, severe injury or con-
siderable damage to equipment.
Measurements and repairs must always be carried out by appropriately qualified personnel.
► Observe the safety instructions in section.
► Always follow the applicable accident prevention and VDE regulations (particularly DIN EN
60 204, part 1) or the regulations specific to your country.

What To Do After Completing Service Work
► Fit the power supply unit and fix in place with the M8 hexagon socket-head screw.
► Make sure that you do not crush the cable when inserting the board.
► Lock the safety doors.
► Remove the key and keep in a safe place.
► Switch the placement system on at the main switch and start it up.

4.1.1.2 Measuring the Power Supply Unit
Measuring the Power Supply Unit
For the position of the modules, refer to "4.1.1.2.1 Front View" [ ➙ 47].
The inputs to the modules all have odd numbers and the outputs have even numbers.
In the case of fuses (F1, etc.), the input is always on the underside of the module, whereas with contac-
tors (SZ1, etc.) and motor circuit-breakers (MS1 ...), it is always at the top.
M8 hexagon socket-head screw to lock the unit
► Switch the placement system off at the main switch.
► Open the safety doors with the double-bit key.
► Loosen the M8 lock screw (1), fastening the under-
side of the unit at the front.
► Pull the unit out as far as the stop.
WARNING! Make sure that the main power ca-
ble and supply cables in the machine are not trapped and
that the insulation is not damaged.
NOTICE
The placement system must be started in order to take these measurements.
This means that the protective covers and component flaps must be closed and the changeover
tables docked. The emergency stop button must be released and the start button pressed. If
this is not the case, the operating voltages will not be switched through to the servo amplifiers,
lifting tables, etc.
