only for versions with outside diameters 22 mm and 42 mm.
• Comply with the installation and safety instructions in the manual.
• Install the device according to the manufacturer's instructions and any other valid standards and
regulations (e. g. IEC/EN 60079-14).
• The type of protection changes as follows when the devices are connected to certified
intrinsically safe circuits of Category ib: Ex ib.
• When interconnecting intrinsically safe circuits, take into account sensor capacitance and
length-dependent cable capacitance and inductance (see table).
• Connect cable screen to earth ground of the installation.
• The intrinsically safe input power circuit of the device is isolated from ground potential and has a
dielectric strength of at least 500 V
rms
with respect to it.
When shortening the length of the cable ensure that this dielectric strength is maintained for
connection wires and earth grounded screen.
• Avoid impact and friction sparks (anchor equipment if necessary/secure against swinging).
• Avoid electrostatic charging of the plastic surfaces (especially at the version with outside
diameter 29 mm and at the terminal box).
Do not rub. Do not use in media or environments which may generate electrostatic charges on
the plastic surfaces.
