4.1 Mounting requirements
The device is designed for use in the field.
Its orientation is determined by the readability of the display.
Operating temperature range:
• –40 to +80 °C (–40 to +176 °F)
• –20 to +80 °C (–4 to +176 °F) when the Open Collector output is used
Operating the device in the upper temperature limit range reduces the operating life of
the display.
The display may respond slowly at temperatures < –20 °C (–4 °F).
Readability of the display can no longer be guaranteed at temperatures < –30 °C (–22 °F).

Both the terminal assignment and the connection values of the field indicator correspond to
those of the hazardous area version. The device is only designed for operation in a 4 to 20 mA
measuring circuit. There must be potential equalization along the measuring circuits (inside
and outside the hazardous area).

5.2 Ensuring the degree of protection
The devices meet all the requirements of IP67. In order to guarantee this after mounting or
after a service case the following points must be observed.
• The housing seal must be clean and undamaged when inserted into the groove. The seal
must be cleaned, dried or replaced if necessary.
• The cables used for connection must have the specified outer diameter (e.g. M20 x 1.5,
cable diameter 8 to 12 mm (0.3 to 0.47 in)). If possible, mount the measuring device so that
the cable entries point downwards.
• Replace unused cable entries with dummy plugs.
• Do not remove the grommet from the cable entry.
• The housing cover and cable entry must be firmly tightened.
