4.2 Electrical input connections
4.2.1 In-head transmitter (Ex and Non-Ex)
Electrical input connections of the in-head transmitter
CAUTION!
Always establish the electrical connections according to the following diagrams. Otherwise it
can come to destruction or damage of the transmitter.
INFORMATION!
To avoid measuring errors, assure that all cables are connected properly and that the screws
are tightened correctly.
DANGER!
"Isolation input/output/PC" as shown in section "Technical data" on page 36 only shows the
signal isolation. This is not an intrinsically safe galvanic isolation, which can be interpreted as an
isolating barrier. Therefore particular care should be applied when selecting the barriers for the
TT 30 C Ex.
