Hauser
Mains voltage
Multi-range power unit for 100 to 240 V AC
The analyzer is fitted with a fuse, T 1.25 A, for the 215
to 240 V AC voltage level. If the analyzer is operated
with 100 to 130 V AC, replace the fuse with the T 2.5 A
fuse supplied. The fuse is located in the cover of the
electronics unit.

If the CA76NA is the last device in the bus segment, the two jumpers must be set to X7
and X8 on the PROFIBUS interface card to incorporate the terminating resistors. If the
analyzer is not the last device in the bus segment, the jumpers must be removed from X7
and X8 on the PROFIBUS interface card.
