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.
