Safety information
Dangers due to automatic restart
The vacuum pump restarts automatically when the power supply
is switched off and then back on, e.g.:
ƒ
after a power failure,
ƒ
after switching the vacuum pump off and on,
ƒ
after disconnecting and reconnecting the power plug.
An ongoing process starts automatically when the power supply is
disconnected and reconnected.
>
Ensure that the automatic restart of the process does not
pose any danger to persons or equipment.
>
Take appropriate safety precautions (e.g., shut‑off valve, relay
switch, protection against restart) if an automatic restart of
the vacuum pump can lead to a dangerous situation.
Hazards due to residual energy
After the vacuum pump has been switched off and disconnected
from the power supply, there may still be dangers due to residual
energy:
ƒ
Thermal energy: engine waste heat, compression heat.
ƒ
Electrical energy: Motor capacitors have a discharge time of up
to 5 seconds.
Please note the following before performing actions:
>
Let the vacuum pump cool down
>
Wait until the capacitors have discharged.
Hazards due to hot surfaces or overheating
CAUTION
Risk of burns from hot surfaces
Depending on operation conditions and ambient condi ‑
tions dangers due to hot surfaces may arise.
>
Avoid direct contact with the surface or wear heat‑re‑
sistant safety gloves if contact cannot be excluded.
>
Provide contact protection if the surface temperature
should be elevated on a regular basis.
