Installation instructions

FM / CSA

The installation, commissioning, maintenance and repair of
devices in areas with explosion hazard must only be carried out
by appropriately trained personnel.
The operator must strictly observe the applicable national
regulations with regard to installation, function tests, repairs,
and maintenance of electrical devices. (e. g. NEC, CEC).

IP protection rating of housing

The temperature transmitter and LCD display type AS must be
installed such that the IP rating of at least IP20 is achieved in
accordance with IEC 60529.
