1.1 Mounting requirements
This instrument is intended for permanent installation, for in-
door 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 characteris-
tics:
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 instru-
ment 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 screw type bracket must be used (see "4. How to
order" paragraph for details).

Note: Terminal 4 can be programmed as:
- Digital Input (DI2) contacts connected to terminals 4 -11;
-
0... 12 V SSR Drive Output (Out4) the load connected between
terminals 4 - 11;
- 12 Vdc (20 mA) power supply for the 2/3 wire transmitters (Out4).
2.1 General notes about wiring
1. Do not run input wires together with power cables.
2. External components (like zener barriers, etc.) con-
nected between sensor and input terminals may cause
errors in measurement due to excessive and/or not bal-
anced line resistance or possible leakage currents.

3. When a shielded cable is used, the protection shield
should be connected to ground at one side only.
4. Pay attention to the line resistance, a high line resist-
ance may cause measurement errors.
