Connection diagram
The connection diagram depicted in Fig. 3.10 shows the instrument connections for turbidity
sensors CUS 31 or CUS 41. The connection of the varrious sensors is shown in more detail in
Figs. 3.13 and 3.14.
Note:
•
The instrument has protection
class II and is generally operated
without protective earth connection.
•
Mains supply voltage fluctuations
should not exceed ten percent of
the nominal supply voltage.
•
24V AC/DC models must be
supplied from an energy limiting
SELV source in accordance with
dir. IEC 1010.1 Annex H.
