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.

Safetyinstructions:
General• The device is intended to be used in explosive atmospheres as definedin the scope of EN IEC 60079-0 or equivalent national standards. If
no potentially explosive atmospheres are present or if additional
protective measures have been taken: The device may be operated
according to the manufacturer's specifications.
• Staff must meet the following conditions for mounting, electricalinstallation, commissioning and maintenance of the device:• Be suitably qualified for their role and the tasks they perform• Be trained in explosion protection• Be familiar with national regulations• Install the device according to the manufacturer's instructions andnational regulations.

Safetyinstructions:
Special conditions

The device may only be connected to SELV/PELV circuits(USB interface). Observe the relevant standards.

XA02790F-A

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 enclosure 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.
