3-2. Preparation
The power/output connections and the sensor connections should be made in accordance with figure 3-
5. The terminals are of a plug in style for ease of mounting.
To open the EXA for wiring:
1. Loosen the four frontplate screws and remove the cover.
2. The terminal strip is now visible.
3.
Connect the power supply. Use the gland on the left for this cable.
4.
Connect the sensor input, using the gland on the right (see fig. 3-5). Switch on the power.
Commission the instrument as required or use the default settings.
5. Replace the cover and secure frontplate with the four screws.
6. Connect the grounding terminals to protective earth.
7. The optional hose connection is used to guide the cables coming from an immersion fitting through a
protective plastic tubing to the transmitter.
Note that the sensor shall have a dielectric strength of 500 Vac with respect to earth and the intercon-
necting circuit to the transmitter shall be installed in such a way that mechanical damage is avoided.
3-2-1. Cables, terminals and glands
The EXA is equipped with terminals suitable for the connection of finished cables in the size range: 0.13
mA
