Basic specifications
The features that are absolutely essential for the device (mandatory
features) are specified in the basic specifications. The number of
positions 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 of
features available. The features have a 2-digit structure to aid
identification (e.g. JA). The first digit (ID) stands for the feature group
and consists of a number or a letter (e.g. J = Test, Certificate). The
second digit constitutes the value that stands for the feature within the
group (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 the
extended order code which are relevant to hazardous locations.

Safety
instructions:
General
• Staff must meet the following conditions for mounting, electrical
installation, 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 and
national regulations.
• Avoid electrostatic charging:
• Of plastic surfaces (e.g. enclosure, sensor element, special
varnishing, attached additional plates, ..)
• Of isolated capacities (e.g. isolated metallic plates)
• Dispose of used battery packs in an environmentally compatible
manner.
• Observe national regulations on waste disposal.
Safety
instructions:
Special conditions
In the event of additional or alternative special varnishing on the
enclosure or other metal parts:
• Observe the danger of electrostatic charging and discharge.
• Do not rub surfaces with a dry cloth.

B1 Direct mounting at field device
B2 Separate mounting with cable connection
• Avoid electrostatic charging (e.g. do not rub dry):
• Of enclosure and antenna
• Of the connecting cable
• Of the "push button" special version (if available)
• The WirelessHART adapter is suitable for use in gases of Groups IIC
and IIB if electrostatic charging (e.g. through friction, cleaning,
maintenance, strong medium flow) is avoided.
• WirelessHART adapter: Indicated by the warning sign
"Avoid Electrostatic Charge".
• Observe the pertinent guidelines when interconnecting intrinsically
safe circuits.
• To maintain the ingress protection of the enclosure:
• Screw the cover tight.
• Mount the cable entry correctly.
• After aligning (rotating) the enclosure, retighten the fixing screw.
• Protect the connecting cable between the WirelessHART adapter and
the field device from tension and friction (e.g. due to electrostatic
charge from medium flow).

Potential equalization
Integrate the device into the local potential equalization.
Safety
instructions:
Zone 1
• Configuring the device: The electronics compartment can be opened
when energized.
• To replace the battery, the WirelessHART adapter may be opened in
hazardous locations.
• Seal unused entry glands with approved sealing plugs that correspond
to the type of protection.
Basic specification, Position 4 = A with "push button" special version
When connecting the device, make sure that the the push-button is still
connected (→  3,  11, Terminals 2 and 5).
Safety
instructions:
Zone 21
• Do not open in a potentially explosive dust atmosphere.
• The battery pack must not be exchanged in dust explosion-hazardous
areas.
• Cable glands with ATEX-Ex e approval and metallic glands: Only use
with an ingress protection of at least IP65. Lay connecting cable and
secure.
• Seal unused entry glands with approved sealing plugs that correspond
to the type of protection.
Basic specification, Position 4 = A
Only suitable for use in Zone 1!
Safety
instructions:
Battery
• Only use the Endress+Hauser battery pack of type BU191 from serial
number: 14/01/xxxxxxxx as specified in the Operating Instructions.
• The PHR2 plug-in connector is designed in such a way that reverse
polarity is not possible.
• Short-circuiting the plus and minus cable trips the irreversible, non-
replaceable fuse.
• In gas explosion-hazardous areas: Only one battery pack of type
BU191 is permitted.
• The safety of the device can be impaired, e.g.:
• In case of visible damage to the battery enclosure
• In case of improper storage
• In case of damage during transportation
