Risks during installation
DANGER
Danger to life from electric shock
Power supply packs that are not specified or are not approved will lead to severe injury to death.
► Make sure that the power supply pack meets the requirements for double isolation between
mains input voltage and output voltage, in accordance with IEC 61010 and IEC 60950.
► Make sure that the power supply pack meets the requirements in accordance with IEC 61010
and IEC 60950.
► Where possible, use original power supply packs or only power supply packs that correspond
with the applicable safety regulations.
DANGER
Danger to life from electric shock
When establishing the voltages that exceed the specified safety extra-low voltage (according to IEC
60449 and VDE 0100), the insulating measures will be destroyed. There is a danger to life from elec-
tric shock at the communication interfaces.
► Connect only suitable devices to the bus system.
WARNING
Risk of injury due to incorrect installation
Dangerous situations may arise from unsafe or incorrect installation.
► Do not carry out your own conversions or modifications on the unit.
► Ensure the integration into an Emergency Off safety circuit.
WARNING
Danger of death from poisoning due to toxic gases being expelled without an exhaust line
Exhaust gases and vapors are released from the turbo pumping station unhindered during normal us-
age. In the case of processes with toxic media, there is a risk of injury and danger of death due to
poisoning.
► Note the corresponding regulations for handling toxic substances.
► Toxic process gases should be safely conveyed away via an exhaust line.
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
Risks during operation
WARNING
Danger of poisoning due to toxic process media escaping from the exhaust pipe
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process
media.
► Observe the pertinent regulations for handling toxic process media.
► Safely purge toxic process media via an exhaust line.
► Use appropriate filter equipment to separate toxic process media.
