5.2.2
Hazard through electrical equipment
5.2.3 Hazards through explosive or ignitable gases
FLSE100-XT sender/receiver units may be used in potentially explosive atmospheres only
according to the respective specifications.
5.2.4 Hazards through electrostatic discharges
The electronic housing of the sender/receiver units and the optionally available spool piece
are painted by the manufacturer with a layer thickness of max. 0.2 mm as standard.
WARNING: Danger through power voltage
▸
Disconnect power supply lines before working on power connections or
parts carrying power voltage.
▸
Refit any contact protection removed before switching the power voltage
back on again.
WARNING: Hazards through explosive or ignitable gases
▸
In potentially explosive atmospheres, only use the version of the
FLSE100-XT sender/receiver units specified for such use (
p. 37, §5.3).
▸
Observe the information on
p. 37, §5.3 during installation work on running
equipment (”hot tapping” method).
WARNING: Ignition hazard through electrostatic discharge
Ignition hazards through electrostatic discharges exist when FLSE100-XT
sender/receiver units with special paintwork and a layer thickness > 0.2 mm
are used in applications with ignition group IIC according to ATEX and IECEx.
▸
For installation, the risk of electrostatic charging of the surface must be
reduced to a minimum.
▸
Use appropriate caution when performing maintenance and cleaning work.
For example, the surfaces should only be cleaned with a damp cloth. The
respective devices will be identified by the manufacturer with a warning
sign.
