WARNING
Risk of fatal injury due to electric shock on account of incorrect installation
The device's power supply uses life-threatening voltages. Unsafe or improper installation can lead to
life-threatening situations from electric shocks obtained from working with or on the unit.
► Ensure safe integration into an emergency off safety circuit.
► Do not carry out your own conversions or modifications on the unit.
WARNING
Risk of fatal injury due to electric shock caused by water damage
The device meets protection degree IP 20 according to EN 60529: 2014 and is not protected against
water ingress. Vacuum pumps operated on the floor lead to leakage current in penetrating and sur-
rounding water. There is a danger to life from electric shock when making contact with live water.
► In case of water damage, disconnect the complete power supply from the area affected.
► Provide an on-site electrical fuse protection (e.g. RCD) in hazardous areas.
► When selecting the installation location, observe potential damage from water.
WARNING
Danger to life from poisoning where toxic process gases leak with no exhaust line
During normal operation, the vacuum pump expels exhaust gases and vapors freely into the air. In
processes involving toxic media, there is a risk of injury and danger to life due to poisoning.
► Observe the relevant regulations for handling toxic substances.
► Safely purge toxic process gases 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.
► Open shut-off units immediately before or at the same time as starting the pump.
► Observe the maximum permissible pressure of 1,500 hPa (absolute).
► 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
Risk of explosion in the medium to be pumped as a result of increased pressure
With installation on the exhaust side, there is a risk of the exhaust pressure of the vacuum pump ex-
ceeding the atmospheric conditions. The ignition temperature of the medium to be pumped is lowered
in the suction chamber. If the ignition temperature of the medium to be pumped falls below a temper-
ature of T4 = +135°C, there is a risk of explosion, and consequently serious injury.
► Ensure that the ignition temperature of the medium to be pumped is maintained above a temper-
ature of +135 °C at 3500 hPa abs.
WARNING
Risk of injury from reactive, potentially explosive or otherwise hazardous gas/air mixtures
Uncontrolled gas inlet of air or gases containing oxygen may lead to the formation of potentially ex-
plosive gas/air mixtures in the vacuum system. Ignition can cause very serious injuries.
► Use inert gases only for the supply of ballast gas in order to prevent the formation of a potentially
explosive atmosphere.
► Ensure a closed inert gas system in order to avoid zone entrainment as a result of process gas
entering into the inert gas line.
