2.3 Electrical Connections
2.3.1 Mains Power
Notice: Generally the local regulations for electrical connections must be observed.
The mains voltage rating for the UL1000 and UL1000 Fab can be read off from the
name plate beneath the mains socket
Fig. 2-6 /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
Fig. 2-6 /7 is available for this purpose
at the back side of the instrument.
Notice: The cable can be secured like shown in the following Figure.
Warning
Before connecting the UL1000 and UL1000 Fab to the mains you must make sure
that the mains voltage rating of the UL1000 and UL1000 Fab 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).
STOP Danger
Caution: mains voltage:
Improperly grounded or fused products can lead to fatal injuries.
Only 3-core mains cables having a protection ground conductor must be used.
Operation of the UL1000 and UL1000 Fab where the ground conductor has been
left unconnected is not permissible.
