Fieldbus Surge Protector
Safety
Instructions for Zone 1
Due to the presence of gas discharge tubes, the surge protective devices do not meet
the dielectric strength requirements according to IEC/EN 60079-11 between the intrinsically
safe circuits and the parts that may be grounded.
Instructions for Zone 21
Due to the presence of gas discharge tubes, the surge protective devices do not meet
the dielectric strength requirements according to IEC/EN 60079-11 between the intrinsically
safe circuits and the parts that may be grounded.
Instructions for Zone 2
Connection or disconnection of energized non-intrinsically safe circuits is only permitted
in the absence of a potentially explosive atmosphere.
If the Surge Protectors are used on couplers spurs rated as Ex ic intrinsically safe circuit,
the trunk module TCP-LBF-IA1.36.* with mounted separation wall must be used.
Due to the presence of gas discharge tubes, the surge protective devices do not meet
the insulation from ground or housing requirements according to IEC/EN 60079-15.
Due to the presence of gas discharge tubes, the surge protective devices do not meet
the dielectric strength requirements according to IEC/EN 60079-11 between the intrinsically
safe circuits and the parts that may be grounded.
The connections must either be mechanically secured or must have a holding force of at least
15 N.
The connections must either be mechanically secured or must have a holding force of at least
15 N. Both, plug and socket connections of FieldConnex surge protectors, device couplers,
and Power Hubs, meet the required holding force of at least 15 N.
Instructions for Zone 22
