WARNING: UNEXPECTED RESTART
Failure or malfuncon of the central control system (unexpected start-up) or danger of a
pump restarng automacally aer switching o due to a fault.
Risk of crushing, cung or cung o 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 anges. Do not
operate the vacuum pump with open anges. When installing the vacuum pump, rst
mechanically connect the inlets and outlets and then make the electrical connecons.
CAUTION: HIGH PRESSURE GAS
Danger due to incorrect connecon of the pump to the system to be pumped out.
Pressure build-up in the vacuum system.
Check correct connecon of inlet and outlet anges 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 malfuncon or power interrupon.
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 connecon and possible residual voltage up to 5 minutes
aer disconnecon from the mains. The electrical connecon may only be carried out by
a trained person. Observe the naonal regulaons 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 interrupon of the protecve conductor system. In the
event of a fault, life-threatening voltages may be present on electrically conducve
components. Before commissioning, check the resistance of the earthing cable and the
suitability of the assigned overcurrent protecon device.
