Electrical installation
1. Loosen the lid clip and unscrew the lid of the enclosure.
2. Unscrew and lift up the digital display (loosen each screw two
turns before completely loosening both, to keep the rubber
retaining rings in place.)
3. Connect the wires to the terminals
4. Ground the instrument according to local regulations.
5. Tighten the cable gland to form a good seal.
6. Fix the digital display.
7. To adjust the transmitter locally, using the keypad, go to
Programming via the Local User Interface (LUI).
After adjustment, replace the enclosure lid and tighten the lid clip.
