Safety information
Hazards during venting
The vacuum pump does not create a vacuum‑tight seal when it
switches off. Depending on the application, venting can cause
explosive mixtures to form in systems or other hazardous
situations to arise.
>
Install a shut‑off valve in the inlet line to isolate your
application from the vacuum pump with a vacuum‑tight seal.
Dangers due to vacuum pump Autostart
The vacuum pump has an Autostart function. When the power
supply is switched off and then back on, the last active operating
state of the vacuum pump is automatically reactivated, 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.
>
Check whether this function can be used safely with the
planned application.
>
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.
>
The Autostart function can be deactivated via Modbus RTU
protocol, see separate manual for Modbus RTU description.
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.
>
Let the vacuum pump cool down before carrying out
maintenance work.
