MOUNTING REQUIREMENTS Select a mounting location where there is minimum vibration and the ambient temperature range between 0 and 50 °C. The instrument can be mounted on a panel up to 15 mm thick with a square cutout of 45 x 45 mm. For outline and cutout dimensions refer to Fig. 2. The surface texture of the panel must be better than 6,3 m. The instrument is shipped with rubber panel gasket (50 to 60 Sh). To assure the IP65 and NEMA 4 protection, insert the panel gasket between the instrument a
