Electrical Connections - Leybold vacuum Sogevac SV65 BI FC Operating Instructions Manual

Connection to exhaust side
No valve or restricting devices should be installed in the exhaust line of the
■
pump. If an exhaust line is installed, it must at least have the same diameter as
the exhaust flange. It should be installed in a manner so that no condensate can
enter the pump (siphon, slope).
The maximum exhaust pressure must neither exceed 1.15 bar absolute (0.15 bar
relative), nor fall under atmosphere pressure minus 15 mbar.
Pump exhaust to be connected if oil mist or process gases are to be avoided in
the pump area.
Corresponding pressure regulating devices to be installed by the user.

Electrical connections

Ensure that incoming power to the pump is off before wiring the motor or
altering the wiring.
IEC & local electrical regulations must be followed.
Should the pump be connected to a standard wall socket, it must be checked
that a building protection rated 16 A is installed (fuse or breaker) to protect the
power cable. The frequency converter itself is self-protecting.
Even if the pump is not operating, live voltage is present in the frequency
converter ! Even after complete power disconnection, allow min. 10 minutes for
a complete capacitor discharge.
Voltage and frequency mentioned on the pump nameplate must agree with the
supply voltage.
See also the F/C manual enclosed at the end of the present document.
The control cable must be at least distant by 10 cm to the mains cable and
crossings shall be at 90°.
Pump control and power supply connection:
See « Ordering information » for the power supply & interface type on the
pump.
The power socket and cord are disconnection elements which must remain
accessible to the users.
Following power cables with connection IEC 320 / C19 exist:
UK
l = 1.8 m
EUR Schuko plug
l = 1.8 m
USA (high V)
l = 1.8 m
