Safety instructions:
General
• 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 and thermal parameters.
• Changes in electrical and mechanical parts of the equipment could harm the type of explosion protection
and are not allowed for the user.
• To maintain the ingress protection of the housing, install the housing cover and cable glands correctly.
• Close unused entry glands with sealing plugs.
• Use a connecting cable for continuous duty temperature T Ta +20 K.
• After aligning (rotating) the housing, retighten the fixing screw (see Operating Instructions) (e.g. secure the
earth connection).
• Install the device to exclude impact and friction sparks on the aluminium housing (F13).
• Connect the sensor and transmitter to the common on-site potential equalization line.
Safety instructions:
Special conditions
• Connecting cable between sensor and transmitter:
– Do not install in the vicinity of processes generating strong electrostatic charges.
– Avoid electrostatic charging of the sensor cable (e.g. do not rub dry and install outside the filling flow).
– Do not leave cable hanging loosely when installed.
– If the connecting cable is removed from both the sensor and the transmitter, ensure that measures are
taken to avoid electrostatic discharge in a potentially explosive atmosphere.

Specification according to IEC/EN 60079-1:2007, Chapter 5.1
• If required or if doubt: ask manufacturer for specifications.
Gammapilot with FEG24
Safety instructions:
Zone 1
• Connect the device using suitable cable and wire entries or using piping systems of protection type
"Pressure-tight Enclosure d".
• Close unused entry glands with approved (Ex d) sealing plugs.
The plastic sealing plug is used only as transport protection.
• Transmitter housing: Do not open in a potentially explosive atmosphere.
• During operation, the cover must be screwed all the way in and the cover's safety catch must be fastened.
• Replace sealing plugs only with identical parts.
• Lay connecting cable to the transmitter and secure.
• The instrinsically safe signal circuit to the sensor is galvanically isolated from other circuits up to a peak value
of the nominal voltage of 375 V.
Safety instructions:
Zone 21
• Connect the device using suitable cable and wire entries or using piping systems.
• Only use suitable cable glands for Zone 21 with degree of protection IP68, which are suitable for an ambient
temperature of at least –40 °C...+70 °C.
• Close unused entry glands with approved sealing plugs.
The plastic sealing plug is used only as transport protection.
• Lay connecting cable to the transmitter and secure.
• Transmitter housing: Do not open in a potentially explosive dust atmosphere.
• Replace cable glands and sealing plugs only with identical parts.
• The instrinsically safe signal circuit to the sensor is galvanically isolated from other circuits up to a peak value
of the nominal voltage of 375 V.
Gammapilot with FEG25
Safety instructions:
Zone 1, Zone 21
• The pertinent guidelines must be observed when intrinsically safe circuits are connected together acc.
EN 60079-14 (Proof of Intrinsic Safety).
• 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 intrinsically safe signal circuit of the sensor is isolated from ground potential and has a dielectric strength
of at least 500 Vrms with respect to it.
• When the device is connected to an intrinsically safe circuit Ex ib, the level of protection changes to Ex ib.
• When the device is connected to an intrinsically safe circuit Ex ic, the level of protection changes to Ex ic.
Do not operate intrinsically safe circuits Ex ic in zone 1 or zone 21.
Safety instructions:
Zone 21, Zone 22
• For service operations, the transmitter housing may be opened under voltage for a short time.
If the terminal compartment is opened make sure that no dust may deposit.
After configuration close the cover according to good professional practice.
