Electrical connections

Caution! Some components inside the sensor are energized with voltages which can
cause lethal shocks in case of contact. The instrument needs to be switched to zero-
potential before any operation on the wiring terminal. Be careful during preparing of
operation, handling and operation of the sensor. This work is to be accomplished in
principle only by qualified technical personnel.
Before opening the cover, it must be ensured that the equipment, in which the sensor
is installed, is in a safe condition (depressurized, empty, rinse, vent, etc.).

Notice: The InPro8600 i / D* turbidity sensor operates with a 24 VDC power supply only.
When only an AC power supply is available on site, the InPro8600 i / D* turbidity sensor
may connect to the 24 VDC terminals from the M800 1-channel transmitter. However,
when 24 VDC power supply is available on site, the InPro 8600 i / D* should be directly
connected to the 24 VDC power source.
