Note!
Observe also XA00332F for the device versions marked with II 2 (1) G and II 2 (1) D:
FMG60-6********, FMG60-7********, FMG60-8********, FMG60-M********.
• Comply with the installation and safety instructions in the Operating Instructions.
• Install the device according to the manufacturer' s instructions and any other valid standards and
regulations.
• Do not operate the device outside the specified electrical, thermal and mechanical parameters.
• To maintain the ingress protection of the housing IP66/IP67, install the housing cover, cable glands
and blind plugs correctly.
• Connect the apparatus to the on-site potential equalization line.
• Cable glands as well as sealing plugs of the terminal compartment A must not be exchanged with
those of the terminal compartment B.
• During operation, the covers must be screwed all the way in and the safety catch of the cover must
be fastened.
• Use connecting cables for continuous service temperature T T
• Do not open the terminal compartment A when energized.
• In an explosive atmosphere: Minimum waiting time before opening the terminal compartment A
after switching off the power supply: 3 minutes.
• Replace cable glands and sealing plugs only with identical parts.
• For service operations, the terminal compartment B (Ex i) may be opened under voltage for a short
time. When the terminal compartment is opened make sure that no dust may deposit.
After configuration screw the cover down to limit stop.
• The safety screws at the pipe housing must not be loosened:
When using the water cooling
• To avoid damages at the detector or at the cooling jacket if the cooling water freezes: Empty cooling
jacket or protect against freezing.
Supplementary cable glands and associated seals
• Only use suitable certified metallic cable glands with an ingress protection of at least IP66.
Avoid electrostatic charging
• In case of additional or alternative special varnishing of the enclosure or other metallic parts:
– Do not rub the surfaces dry.
– Do not install in the vicinity of processes generating strong electrostatic charges.
• Avoid electrostatic charging:
– Of plastic surfaces (e.g. housing, sensor element, special varnishing , attached additional plates, ..)
– Of isolated capacities (e.g. isolated metallic plates)
• The pertinent guidelines must be observed when intrinsically safe circuits are connected together
acc. to EN 60079-14 (Proof of Intrinsic Safety).
• The instrinsically safe circuits are galvanically isolated from other circuits up to a peak value of the
nominal voltage of 375 V.
• The intrinsically safe circuits of the device are isolated from ground potential and has a dielectric
strength of at least 500 V
• When the device is connected to an intrinsically safe circuit Ex ib, the type of protection changes to
Ex ib. Do not operate the temperature sensor in Zone 20 if the device is connected to an intrinsically
safe circuit of Category Ex ib.
• When the device is connected to an intrinsically safe circuit Ex ic, the type of protection changes to
Ex ic. Do not operate the temperature sensor in Zone 20 or Zone 21 if the device is connected to an
intrinsically safe circuit of Category Ex ic.
• For grounding the screen, →  2.
