5. Commissioning, operation
5.1.3 Temperature load
The installation of the instrument should be made in such a way that the permissible
operating temperature, also considering the effects of convection and thermal radiation,
neither exceeds nor falls below the permissible limits.
The temperature effect on the indication and measurement accuracy must be observed.
5.2 Electrical connection
5.2.1 Connection lead
With the selection of connection leads, the following points must be noted:
Conductor cross-section must be selected corresponding to the load current/overcur-
rent protection device.
The sealing range of the supplied cable gland must fit the conductor diameter.
The temperature range of the cable must correspond, as a minimum, to the operating
temperature range of the instrument.
→ For specifications, see chapter 9 "Specifications".
5.2.2 Grounding
The main instrument must be grounded via the process connection.
Fasten the protective conductor of the connection cable for the switch contacts to the
terminal (1) provided for this purpose as shown in the figure below.
Never remove the protective conductor connection cable (2) between the main
instrument and the counterpart of the cable socket. Otherwise, operational safety
cannot be ensured.
