for collecting liquid, which may pos-
sibly come into the pump.
The Vacuum Regulator allows for
control of the vacuum level be-
tween atmospheric pressure and
ultimate pressure of the pump.

Connecting to the electricity supply
The WOB-L
®
Piston Pumps are supplied with complete electrical wiring. It is connected via a
mains connection cable and a power plug. Mains connection cable and plug must comply
with the requirements of the line disconnection devices (current, output).
Motor is provided with a thermal overload protection ex works, protecting the vacuum pump
from damage or destruction, respectively.
WARNING !
Should the user change the electrical connection, for example for fitting into a sys-
tem, then this may only be performed by a electrical specialist under observance of
the accident prevention regulations.
3.1.3
Display
– Vacuum Regulator
The Vacuum Regulator shows pressures at below atmospheric pressure.
The reference point is atmospheric pressure.
WARNUNG !
Please keep in mind that the barometric pressure changes from day to day.
This also changes the displayed pressure values because of latent air pressure
fluctuations.
