It is recommended that you check all major helium sources in the vicinity of the
UL5000 within a radius of about 10 m for the presence of any big leaks. You may use
the sniffer probe for this.

Electrical Connections
2.3.1
Mains Power
Notice:
Generally the local regulations for electrical connections must be observed.
The mains voltage rating for the UL5000 can be read off from the name plate beneath
the mains socket
/7 at the back side. This voltage is fixed and can not be
changed.
A separate fuse for each of the mains conductors has been integrated into the mains
switch.
The mains voltage is applied to the instrument via the detachable mains cable which
is supplied with the instrument. A mains socket
/7 is available for this purpose
at the back side of the instrument.
STOP
Danger
Caution: Exhaust gases and fumes:
Exhaust gases and fumes from oil-sealed pumps may be harmful to health.
For operation in poorly ventilated rooms, an exhaust pipe should be connected to
exhaust connection 5 depending on the application and gases used.
STOP
Danger
Caution: mains voltage:
Improperly grounded or fused products can lead to fatal injuries.
The product must be connected in accordance with local regulations and properly
grounded. Interruption of the ground conductor within or outside of the device is not
permitted!
Only fuses of the specified type and rating are to be used as replacements.
Warning
Before connecting the UL5000 to the mains you must make sure that the mains
voltage rating of the UL5000 coincides with the locally available mains voltage. The
instrument must exclusively be connected to a single phase supply with fuses for
installation (Circuit breaker 16A max. according to IEC/EN 60898 with tripping
characteristic B).
