Important Safety Information
0.1 Mechanical Hazards
1
Never expose part of the body to the vacuum. There is a danger of
injury. Never operate the pump with an open and thus accessible inlet.
Vacuum connections as well as oil filling and oil draining openings
must not be opened during operation of the pump.
0.2 Electrical Hazards
1
Disconnect the unit from the power supply before starting any work or
pull the mains plug.
2
High electric voltages! When touching parts at high electric voltages,
there is the risk of suffering severe injuries by an electric shock! Covers
marked with this symbol must only be opened by trained electricians
after having reliably deenergised (lockout/tagout) the equipment and
waited minimum 10 minutes.
3
Always operate the pump with a properly connected protective earth
conductor and make sure that the motor & FC connection box are
closed.
4
Observe the manufacturer’s information and operating instructions for
the respective frequency converter (enclosed).
5
Use only the Leybold frequency converter for the pumps equipped
with one.
6
After having made changes to the wiring, check the motor’s direction
of rotation.
7
Lay the connecting lines so that these cannot be damaged. Protect
the lines against humidity and contact with fluids.
8
Avoid thermally stressing the lines by unfavourable laying. Provide
strain relief for the connecting lines so that the plugs and the line con-
nectors are not subjected to excessively high mechanical stresses.
9
Lay electric feed lines so that there is no risk of tripping over these.
