• Install the device according to the manufacturer's instructions and any other valid standards and regulations.
• The intrinsically safe input power circuit of the device is isolated from ground potential and has a dielectric
strength of at least 500 Vrms with respect to it.
• The relationship between the permitted ambient temperature for the electronics housing, dependent on the
range of application and the temperature classes is shown in the tables (Tab. 1).
• Continuous duty temperature of the cable ≥ Ta +5 K.
• The type of protection changes as follows when the devices are connected to certified intrinsically safe
circuits of Category Ex ib for Equipment Groups IIC and IIB: Ex ib IIC or Ex ib IIB.
• The pertinent guidelines must be observed when intrinsically safe circuits are connected together acc.
IEC/EN 60079-14 (Proof of Intrinsic Safety). (E.g. when using Commubox or handheld terminal DXR375
or other certified apparatus).
FMU42, FMU44
• Avoid electrostatic charging of the sensor (e.g. do not rub dry and install outside the filling flow).
