A*B*C*D*E*F*G*..
(Optionalspecifications)* = Placeholder
At this position, an option (number or letter) selected from thespecification is displayed instead of the placeholders.
Basic specifications
The features that are absolutely essential for the device (mandatoryfeatures) are specified in the basic specifications. The number ofpositions depends on the number of features available.
The selected option of a feature can consist of several positions.
Optional specifications
The optional specifications describe additional features for the device(optional features). The number of positions depends on the number offeatures available. The features have a 2-digit structure to aid
identification (e.g. JA). The first digit (ID) stands for the feature groupand consists of a number or a letter (e.g. J = Test, Certificate). The
second digit constitutes the value that stands for the feature within thegroup (e.g. A = 3.1 material (wetted parts), inspection certificate).
More detailed information about the device is provided in the following
tables. These tables describe the individual positions and IDs in theextended order code which are relevant to hazardous locations.
Extended order code: Commubox
The following specifications reproduce an extract from the productstructure and are used to assign:• This documentation to the device (using the extended ordercode on the nameplate).
• The device options cited in the document.

Commubox FXA195• The device is an associated apparatus: Only use the device outside
explosion hazardous areas.
• The intrinsically safe connections of the device may be routed toZone 0 and Zone 20.
• There must be a distance of at least 50 mm between terminals of
external intrinsically safe circuits and terminals or bare components
of non-intrinsically safe circuits.
• Keep a minimum distance (air gap):• 3 mm between the bare components of the intrinsically safe circuitand metal housing components• 6 mm between bare components of intrinsically safe and nonintrinsically safe circuit• The intrinsically-safe circuit is galvanically isolated from othercircuits up to a peak value of the nominal voltage of 375 V.
• If an intrinsically safe circuit is connected to the device passes
through dust explosion-hazardous areas of Zones 20 or Zone 21,
make sure that the devices connected to this circuit meet therequirements of categories 1 D or 2 D and are certified accordingly.
