WARNING: UNEXPECTED RESTART
Failure or malfunction of the central control system (unexpected start-up) or danger of a
pump restarting automatically after switching off due to a fault.
Risk of crushing, cutting or cutting off by touching moving parts due to recurring start
command or power supply.
Before carrying out maintenance or service work, disconnect the pump from the power
supply, secure it against being switched on again, determine that it is de-energised,
ground and short-circuited and cover / isolate adjacent live parts.
CAUTION: RISK OF INJURY
Pulling in of body parts and objects into the vacuum through open flanges. Do not
operate the vacuum pump with open flanges. When installing the vacuum pump, first
mechanically connect the inlets and outlets and then make the electrical connections.
CAUTION: HIGH PRESSURE GAS
Danger due to incorrect connection of the pump to the system to be pumped out.
Pressure build-up in the vacuum system.
Check correct connection of inlet and outlet flanges before commissioning. When using
the pump with seal gas, protect the seal gas supply so that no overpressure can occur in
the pump system in the event of a malfunction or power interruption.
CAUTION: TRIP HAZARD
Slipping, tripping or falling as a result of oil leaking from the pump. Oil can escape from
the vacuum pump during pumping or depending on the work process. Risk of falling on
oil spills. Check the vacuum pump regularly for oil leaks. Take the appropriate safety
measures
2.2 Electrical hazards
DANGER: ELECTRICAL SHOCK
Risk of electrical shock caused by direct or indirect contact with live parts. Electrical
shock due to faulty electrical connection and possible residual voltage up to 5 minutes
after disconnection from the mains. The electrical connection may only be carried out by
a trained person. Observe the national regulations in the user country, e.g. for Europe EN
50110 - 1. Prior to servicing, disconnect the vacuum pump from the power supply.
Risk of 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.
