Safety notes
EN
For mounting and installation
EN
• Observe national installation regulations (e.g. IEC/EN 60079-14).
EN
• Observe national safety and accident prevention regulations.
• During installation and operation, observe the information (characteristic values and
EN
rated operating conditions) on the rating, data and information plates located on the
EN
device.
EN
• Before installation, make sure that the device is not damaged.
• Electric circuits with type of protection "Ex i" operated with circuits with other types of
EN
protection can no longer be operated as circuits with type of protection "Ex i" after that.
EN
• When used in Zones 2 and 22, the intrinsically safe devices of Zones 1, 0, 21 and 20
EN
can be connected to the intrinsically safe signal circuits.
• The safety characteristic values of the connected field devices must correspond to the
EN
specifications in the data sheet or in the EC Type Examination Certificate.
EN
• Interconnecting several devices in a single intrinsically safe circuit can result in
EN
different safety characteristic values. This may impair intrinsic safety!
• Before carrying out work on the device, the body's own voltage must be discharged on
EN
earthed metal parts or an ESD wrist strap must be put on.
EN
• Connect the device only to equipment which does not carry voltages higher than 253
EN
V AC (50 Hz).
• Ensure that there is a distance of at least 50 mm (tight string length) between
EN
connecting units of intrinsically safe and non-intrinsically safe circuits when setting up
EN
field circuits.
EN
• The power supply of 24 V DC must be able to bridge brief interruptions of 20 ms in
order to ensure power failure bridging according to IEC/EN 61326-3-2 and NE 21.
EN
EN
Maintenance, repair, commissioning
EN
• Before commissioning, make sure that the device is not damaged.
EN
• Work on the device, such as installation, maintenance, overhaul, repair, may only be
carried out by appropriately authorised and trained personnel.
EN
• Perform only maintenance work or repair described in these operating instructions.
EN
• For SIL applications observe the safety manual and FMEDA reports.
EN
• Make sure to use suitable cables and cable glands for temperatures below -20 °C.
• The configuration interface of the device can only be connected to a non-sparking
equipment with low power rating (according to IEC/EN 60079/15, chapter 13) or for
maintenance purposes in compliance with IEC/EN 60079-17, chapter 4.6.
