This instrument has been designed to be permanently fitted in
a control panel.
Select a location, for instrument mounting, where minimum
vibrations are present and the ambient temperature is within 0
and 50 °C (32 and 122 °F).
The instrument can be mounted on a panel up to 15 mm thick with
a 45 x 22.2 mm square cutout.
For outline and cutout dimensions refer to Fig. A.
The surface texture of the panel must be better than
6,3 µm.
The instrument is shipped with rubber panel gasket.
To assure the IP65 and NEMA 4 front protection, insert the panel
gasket between the instrument and the panel as shown in fig. 1.
For the instrument mounting proceed as follows:
1) insert the gasket in the instrument case;
2) insert the instrument in the panel cutout;
3) pushing the instrument against the panel, insert the mounting
bracket and press it against the panel.

NOTE NOTE NOTE: Any external component (like zener barriers etc.) NOTE NOTE
connected between sensor and input terminals may cause
errors in measurement due to excessive and/or not balanced
line resistance or possible leakage currents.

1) Don't run input wires together with power cables.
2) For TC wiring use proper compensating cable preferable
shielded.
3) When a shielded cable is used, it should be connected at one
point only.
