The safety screws at the pipe housing must not be loosened:
A0031759
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.
Intrinsic safety
• Observe the pertinent guidelines when interconnecting intrinsically safe circuits.
• The intrinsically-safe input 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 and have a dielectric strength
of at least 500 V
rms
.
• 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 0 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 0 or Zone 1 if the device is connected to an
intrinsically safe circuit of Category Ex ic.
• Do not interconnect the 4...20 mA/HART signal circuits of the devices of a cascade set.
Increased safety (Ex eb)
• Only use suitable certified Ex eb cable glands providing an ingress protection of at least IP66/67.
The cable glands must be suitable for the intended ambient temperature range.
• Replace cable glands and sealing plugs only with identical parts.
Flameproof enclosure (Ex db)
• Connect the device:
– Using suitable cable and wire entries of protection type "Flameproof Enclosure (Ex db)".
– Using piping systems of protection type "Flameproof Enclosure (Ex db)".
• Seal unused entry glands with approved Ex db sealing plugs.
Safety instructions: Ex db joints
If required or if in doubt: ask manufacturer for specifications.
Potential equalization
Integrate the device into the local potential equalization.
