2.2 Electrical hazards
CAUTION: ELECTRICAL SHOCK
Cont
act with live parts may lead to electrical shock.
The electrical connecon may only be carried out by a trained person. Observe the
naonal regulaons 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 interrupon of the protecve conductor system. In the event
of a fault, life-threatening voltages may be present on electrically conducve
components.
Before commissioning, check the resistance of the earthing cable and the suitability
of the assigned overcurrent protecon device.
The pump must only be connected to power supplies which meet the requirements
for funconal extra-low voltages with posive isolaon in accordance with IEC
60364-4-41 (or local regulaons) (PELV). All interfaces must only be operated with
PELV-fed components and devices.
2.3 Thermal hazards
CAUTION: BURNS
Touching hot surf
aces may lead to burns.
Handle the pump only when venlated and cooled down.
Wear suitable protecve equipment.
2.4 Danger through materials and substances
WARNING: HAZARDOUS SUBSTANCES
Pumped process g
ases 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 / ammable / pyrophoric / radioacve / oxidizing /
corrosive gases or gas mixtures, as well as oxygen of more than atmospheric
concentraon (21 %) is generally prohibited. The operator is responsible for assessing
the hazard potenal of the process media or mixtures.
