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 fluid (i.e. condensation).
5) the ambient temperature is in accordance with the
operative temperature (from 0 to 50 °C).
6) the relative humidity is in accordance with the
instrument specifications ( 20% to 85 %).
The instrument can be mounted on OMEGA rail in
accordance with EN 50 022 (35 x 7.5 mm or 35 x 15
mm) regulations.
2.2 GENERAL NOTES ABOUT INPUT WIRING
1) Don't 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.
3) When a shielded cable is used, it should be
12
connected at one point only.
4) Pay attention to the line resistance; a high line
resistance may cause measurement errors.

External resistance: 100 Ω max, maximum error 0,5 %
of span.
Cold junction: automatic compensation from 0 to 50 °C.
Cold junction accuracy : 0.1 °C/°C after a warm-up of
20 minutes
Input impedance: > 1 MΩ
Calibration: according to EN 60584-1.
NOTE: for TC wiring use proper compensating cable
preferable shielded.
