Setting up and installing the equipment
➨
Equipment must be connected only to a
suitable elec-
trical supply
and a suitable ground point. As such,
the plug must be plugged into an outlet that is properly
grounded. Failure to connect the motor to ground may
result in deadly electrical shock.
The supply cable may be fitted with a molded Europe
-
an IEC plug or a plug suitable for your local electrical
supply. The cable contains wires color coded as fol-
lows: green or green and yellow: ground; blue or white:
neutral; brown or black: hot.

Due to the high compression ratio, the pump may gen-
erate overpressure at the outlet. Check pressure com-
patibility with system components (e.g., exhaust pipe-
line or exhaust valve) at the outlet.
+
Do not permit any
uncontrolled pressurizing
. Make
sure that the exhaust tubing cannot become blocked. If
there is an exhaust isolation valve, make sure that you
cannot operate the equipment with the valve closed to
avoid a
risk of bursting!
+
Keep the electrical power cord away from heated sur-
faces.
• Provide a firm, level platform for the equipment. Check
that the system which you are going to evacuate is
mechanically stable. Check that all fittings are secure.
Ensure a stable position of the pump without any me-
chanical contact other than the pump feet.
• Comply with
maximum permissible pressures
at in-
let and outlet and with
maximum permissible pres-
sure differences
between inlet and outlet. See section
“Technical data”, pg. 19. Do not operate the pump
with overpressure at the inlet.
• Avoid overpressure of more than 17.5 psi absolute (1.2
bar absolute) in the event that gas or inert gas is con-
