1.5 Safety instructions
WARNING
The safety instructions from the “Operational safety” chapter of the user manual and servicing
instructions take precedence over these instructions. 1
The SIPLACE placement machines are supplied with mains voltage.
Consequently parts of these systems carry dangerous voltages! This voltage is present at cer-
tain modules inside the machine base, even when the machine is switched off at the main power
switch.
Incorrect handling of the placement machine or touching live parts of the machine can result in
death or severe injury, and considerable damage to equipment.
BEFORE starting any work, shut down the operating system correctly, then switch the machine
OFF at the main power switch and disconnect from the main power supply. In addition, the com-
pressed air supply must be switched off at the compressed air unit's main valve in the machine
base and vented by actuating the needle valve on the compressed air unit.
There is DANGER for heart pacemaker wearers in the vicinity of the linear motors, as described
in detail in the "Special safety instructions for working in the vicinity of strong magnetic fields"
section of the user manual and service manual.
Always follow the accident prevention regulations, DIN or other standards and special safety
rules applicable in your country.
Pay attention to the information concerning residual voltages in the Operational Safety chapter.
Follow the ESD regulations as described in the operational safety section of the operating
instructions.
During the retrofit, always secure the machine to prevent access by other people and to prevent it
being switched on again. The procedure is described in the “Locking the machine…” section of
the user manual.
Working with the SITEST program further increases the risk of accident.
The SITEST program must only be used by authorized and trained personnel.
