6. Information on mounting and operation in ...
The ambient temperature of the current loop display can be altered by
additional components (e.g. through heat dissipation in the case, in
particular with a transmitter mounted within the case or by mounting it
in the connection head of a temperature probe with the radiated heat
EN
from the medium). The operator of the display must ensure that, even
in the event of a failure, the maximum permitted ambient temperature
of 60 °C is not exceeded.
The operation of this explosion-protected version is only permitted in
intrinsically safe circuits.
The programming set for the factory programming must only be used
by the manufacturer, as it does not have ATEX approval!
The programming of the display must only be made via the three
buttons at the rear of the display!
When cases are used, they must either have their own suitable
approval or comply with the minimum requirements.
IP protection of at least IP20 applies for all cases
However, light metal cases must be qualified in accordance with
IEC/EN 60079-0 section 8.1. In addition, non-metallic cases or
powder-coated cases must meet the electrostatic requirements of
IEC/EN 60079-0 or have a suitable warning note.
The current loop display can be built into either a model BSZ-H
connection head or BSS-H connection head (with or without
wall-mounting adapter). In this case, the case requirements referred
to are fulfilled. The cases are not constituent elements of the EC-type
examination certificate.
