2.1.4 Safety Instructions for the Power Supply
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 considerable damage to
equipment.
Measurements and repairs must always be carried out by appropriately qualified personnel.
Always follow the safety instructions in the Siplace HF Operating Instructions.
Always follow the applicable accident prevention and VDE regulations (particularly DIN EN 60 204, part 1) or the
regulations specific to your country.
Before starting any repairs, switch off at the main switch and disconnect the placement system from the main
power supply.
Always secure the machine against unauthorized reactivation. If these instructions are not followed, it is possible to
touch live parts, which could result in death or severe injury.

Exchanging components
End all placement operations on the placement system.
Shut down the Windows NT operating system correctly, otherwise problems may occur when restarting or data may
be lost.
Switch the placement system off at the main switch.
Disconnect the placement system from the main power supply.
Switch off the machine and attach warnings signs to indicate that service work is in progress.
2.1.5 Safety Instructions for the Compressed Air Supply
CAUTION
When the machine is switched on, do not use the shutoff valve to interrupt the compressed air supply for more than 30
minutes. If you need to shut off the pneumatic system for longer, in order to carry out maintenance or servicing work, you
must switch the placement system off at the main switch and disconnect it from the power supply.
WARNING
NEVER detach compressed air lines while they are still pressurized. Risk of injury!
