2.1 MOuNTING REquIREMENTS

This instrument is intended for permanent installation, for
indoor use only, in an electrical panel which encloses the
rear housing, exposed terminals and wiring on the back.
Select a mounting location having the following characteristics:
1.  It should be easily accessible;
2.  There is minimum vibrations and no impact;
3.  There are no corrosive gases;
4.  There are no water or other fluids (i.e. condensation);
5.  The ambient temperature is in accordance with the

operative temperature (0... 50°C);

6. The relative humidity is in accordance with the instrument

specifications (20... 85%);

The instrument can be mounted on panel with a maximum
thickness of 15 mm.
When the maximum front protection (IP65) is desired, the
optional gasket must be monted.

2.2 GENERAL NOTES AbOuT wIRING

1. Do not run input wires together with power cables.
2. External components (like zener barriers, etc.) connected

between sensor and input terminals may cause errors in
measurement due to excessive and/or not balanced line
resistance or possible leakage currents.
