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 and the panel as shown in fig. 1. While holding the instrument against the panel 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; 4) with a screwdriver, turn the screws with a torque between 0.3 and 0.4 Nm.
