tric shock at the communication interfaces.
►Connect only suitable devices to the bus system.
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.
NOTICE
Property damage on the electronics
Separating all plug-and-socket connections within the bus system with voltage supply switched on
may lead to the destruction of electronic components.
►Always disconnect the voltage supply before removing the connecting plug.
►After switching off the power supply pack, wait until the residual load has dispersed completely
before disconnecting the plug-and-socket connection.
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.
WARNING
Risk of explosion from reactive, explosive or other hazardous gas / air mixtures.
Uncontrolled inlet of gas at the flushing gas nozzle leads to sparks generated mechanically following
diaphragm rupture, hot surfaces or to explosive gas / air mixtures in the vacuum system caused by
static electricity.
►If necessary, use inert gas for supplying the flushing gas in order to avoid a potential ignition.
Safety
11/50

CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C.
►Provide suitable touch protection.
CAUTION
Risk of poisoning due to toxic process gases escaping
For intake pressures > 500 hPa, process gas may escape from the flushing gas nozzle.
►If necessary, use an extraction line.
NOTICE
Vacuum pump damage caused by overpressure
Mixing up the connections causes overpressure overload. The vacuum pump can be started only
against max. 1 bar differential pressure between inlet and outlet; otherwise the motor jams and sus-
tains damage.
►Make sure that the distributor is installed correctly on the diaphragm heads, before connecting
the vacuum pump to the vacuum equipment.
►Before commissioning, make completely sure that the pressure side pressure is below the per-
missible limit.
Risks during maintenance, decommissioning and in event of malfunctions
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
►Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
►Decontaminate affected parts before carrying out maintenance work.
►Wear protective equipment.
CAUTION
Danger of injury from moving parts
After a power failure or a standstill as a result of overheating, the motor restarts automatically. There
is a risk of injury to fingers and hands if they enter the operating range of rotating parts.
