MOUNTING REQUIREMENTS

Select a mounting location with the following characteristics:

1)Minimal vibration.

2)An ambient temperature range between 0 and 50°C (32 and 122 °F).

3)Easy access to the rear of the instrument.

4)No corrosive gases (sulfuric gas, ammonia, etc.).

5)No water or other fluid (i.e. condensation).

6)Relative humidity of 20% to 80% non condensing.

The instrument can be mounted on a panel up to 15 mm (0.591 in) thick with a square cutout of

45 x 45 mm (1.772 x 1.772 in). For outline refer to Dimensions and Panel Cutout.

Panel surface texture must be better than 6.3 µm.

The instrument is shipped with a rubber panel gasket (50 to 60 Sh). To insure the IP65 and NEMA 4 protection, insert the panel gasket between the instrument and the panel as shown below.

Install the instrument as follows:

1)Insert the instrument in the gasket.

2)Insert the instrument in the panel cutout.

3)Pushing the instrument against the panel, insert the mounting bracket.

4)Torque the mounting bracket screws between 0.3 and 0.4 Nm (2.66 and 3.54 lbf-in).

5)To insure NEMA 4X/IP65 protection, make sure the instrument does not move within the cutout .
