0.2 Electrical hazards
CAUTION: ELECTRICAL SHOCK
Contact with live parts may lead to electrical shock.
The electrical connection may only be carried out by a trained person. Observe the national reg-
ulations in the user country, e.g. for Europe EN 50110 - 1. Prior to servicing, disconnect the
vacuum pump from the power supply.
Electrical shock due to interruption of the protective conductor system. In the event of a fault,
life-threatening voltages may be present on electrically conductive components.
Before commissioning, check the resistance of the earthing cable and the suitability of the
assigned overcurrent protection device.
The pump must only be connected to power supplies which meet the requirements for functional
extra-low voltages with positive isolation in accordance with IEC 60364-4-41 (or local regulations)
(PELV). All interfaces must only be operated with PELV-fed components and devices.
0.3 Thermal hazards
CAUTION: BURNS
Touching hot surfaces may lead to burns.
Handle the pump only when ventilated and cooled down.
Wear suitable protective equipment.
0.4 Danger through materials and substances
WARNING: HAZARDOUS SUBSTANCES
Pumped process gases may escape from the exhaust and leaks in the vacuum system.
During servicing, toxic deposits may be present in the pump. The gases, vapours or substances
may be hazardous to health.
The pumping of toxic / explosive / flammable / pyrophoric / radioactive / oxidizing / corrosive
gases or gas mixtures, as well as oxygen of more than atmospheric concentration (21 %) is gen-
erally prohibited. The operator is responsible for assessing the hazard potential of the process
media or mixtures.
0.5 Dangers in connection with safety-related
measures and precautions
CAUTION: AUTOMATIC START-UP
The frequency converter is not equipped with its own emergency shut down switch. This may
lead to an unwanted pump start-up.
Install an emergency shut down switch in the system. The emergency shut down switch must be
■
present in the building installation
■
suitably arranged and easily accessible for the user
■
marked as the disconnecting device for this device.
