Safety instructions:
Installation
Endress+Hauser
• 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 290 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 and Tab. 3).
• After aligning (rotating) the housing, retighten the fixing screw (Allen screw on the threaded neck).
• Continuous duty temperature of the cable ≥ Ta +5 K.
• If antenna extensions over 3 m-long are used, they should be fixed mechanically (using guy ropes).
• FMR240 or FMR230 with shut-off mechanism:
the entire arrangement must at least meet the requirements as per IP67 in accordance with IEC/EN 60529.
If the device needs to be disassembled for e.g. service purposes, we recommend securing the
shut-off mechanism against opening or closing it with an additional blind flange.
The operator is entirely responsible for ensuring that the complete arrangement is permissible for the
respective application.
• In case of additional or alternative special varnishing of the enclosure or other metallic parts the danger of
an electrostatic charging must be observed. Do not rub surfaces with dry cloth.

• 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 T6 or Ex ib IIB T6.
Do not operate the antenna in Zone 0 if the transmitter is connected to an intrinsically safe circuit of Category
Ex ib.
• 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).
