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).

Safetyinstructions:
General• 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.
• Avoid electrostatic charging:• Of plastic surfaces (e.g. housing, sensor element, specialvarnishing, attached additional plates, ..)• Of isolated capacities (e.g. isolated metallic plates)• Dispose of used battery packs in an environmentally compatiblemanner.
• Observe national regulations on waste disposal.

Safetyinstructions:
Special conditions

In the event of additional or alternative special varnishing on thehousing or other metal parts:• Observe the danger of electrostatic charging and discharge.
• Do not rub surfaces with a dry cloth.

WirelessHART adapter SWA70• Avoid electrostatic charging (e.g. do not rub dry):• Of housing 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 intrinsicallysafe circuits.
• To maintain the ingress protection of the housing:• Screw the cover tight.
• Mount the cable entry correctly.
• After aligning (rotating) the housing, retighten the fixing screw.
• Protect the connecting cable between the WirelessHART adapter andthe field device from tension and friction (e.g. due to electrostatic
charge from medium flow).
Basic specification, Position 4 (Housing) = A
Torque must be observed:• Cover screws: 0.7 Nm ±10 %• Cable glands: 3.25 Nm ±10 %• Sealing plug: 3.25 Nm ±10 %Basic specification, Position 4 (Housing) = B, C
Torque must be observed:• Cover screws: 0.7 Nm ±10 %• Cable glands: 6.25 Nm ±10 %• Sealing plug: 6.25 Nm ±10 %Potential equalization
Integrate the device into the local potential equalization.

Safetyinstructions:
Zone 1• Configuring the device: The electronics compartment can be opened
when energized.
• To replace the battery, the WirelessHART adapter may be opened inhazardous locations.
• Seal unused entry glands with approved sealing plugs that correspondto the type of protection.
Basic specification, Position 4 (Housing) = A with "push button" special
versionWhen connecting the device, make sure that the the push-button is stillconnected (→  3,  10, Terminals 2 and 5).

Safetyinstructions:
Zone 21

XA01505F-C• 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 andsecure.
• Seal unused entry glands with approved sealing plugs that correspondto the type of protection.
Basic specification, Position 4 (Housing) = A
Only suitable for use in Zone 1!

Safetyinstructions:
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, nonreplaceable 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 housing• In case of improper storage• In case of damage during transportation
