5.1. Preparing the connection
Always observe the following safety instructions:
•
When you are going to install instruments in hazardous
area or install instruments which are connecting to
instruments are working in hazardous area you should take
note of the appropriate regulations, conformity and type
approval certificates of the DT9102 I4 and the other
instruments (e.g. isolator, Zener barrier). The connection
must be carried out by trained and authorized personnel
only!
Take note of the corresponding installation regulations for
Ex applications. In particular, make sure that no potential
equalization currents flow over the cable screen. Ground
only one side the cable screen.
•
Use only a screwdriver with appropriate head.
Take note the suitability of the connecting cable
(wire cross-section, insulation, cable screen, etc.).
The wire cross-section should be 0.25–1.5 mm
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
1. Remove approx. 30 mm of cable mantle, strip
approx. 8 mm insulation.
2. Remove the instrument front cover (see chapter 4.3.).
3. Loosen compression nut of the cable entry.
4. Insert the cable into the instrument through the cable
entry.
1. Push the cable-end until it possible into the terminal
assembly.
2. By pushing the wire in, the self-closing connection is
being established. Check it by pulling it outwards slightly.
(3. When you disassemble the cable, push down the white
button by a screwdriver, and pull the cable-end out.)
There is no need to use great force for pushing the cable in,
neither for removal. The button can be pushed down easily.
Please do not exercise forces higher than necessary, as it
may cause damages to the terminal assembly.
