2 Use in potentially explosive
atmospheres
DANGER
Danger of explosion if the device is operated with the
transmitter housing or terminal box open!
Before opening the transmitter housing or the terminal box,
note the following points:
— Check that a valid fire permit is available.
— Make sure that there is no explosion hazard.
— Before opening the device, switch off the power supply
and wait for t > 2 minutes.
2.1 Obligations of the owner
2.1.1 ATEX, IECEx, NEPSI
The installation, commissioning, maintenance and repair of
devices in areas with explosion hazard must only be carried
out by appropriately trained personnel.
When operating the meter in the presence of combustible
dusts, IEC 61241 ff must be complied with.
The safety instructions for electrical apparatus in potentially
explosive areas must be complied with, in accordance with
Directive 94/9/EC (ATEX) and IEC60079-14 (Installation of
electrical equipment in potentially explosive areas).
To ensure safe operation, the requirements of EU Directive
ATEX 118a (minimum requirements concerning the protection
of workers) must be met.
2.1.2 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).

Switch output
The switch output is designed as an optoelectronic coupler or
a NAMUR contact (in accordance with DIN 19234).
— When the NAMUR contact is closed, the internal
resistance is approx. 1000 Ω.
— When the contact is open, the internal resistance is
> 10 kΩ.
The switch output can be changed over to "optoelectronic
coupler" if required.
— NAMUR with switching amplifier
