Safety instructions
1.1
Designated use
The WirelessHART Adapter SWA70 is a smart wireless module designed for the wireless
transmission of 4 to 20 mA HART signals from connected field devices to a WirelessHART Fieldgate.
Information about the designated use of the connected field devices and the Fieldgate is provided
in the devices' individual operating manuals.
1.2
Installation, commissioning and operation
The WirelessHART Adapter can be operated safely in compliance with the current technical safety
standards and the applicable EU guidelines. Field devices connected to the WirelessHART Adapter
must also be operated in accordance with the current technical safety standards and the applicable
EU guidelines.
The WirelessHART Adapter can be a source of danger if it is not installed correctly or if it is used in
applications for which it is not intended.
The WirelessHART Adapter may only be installed, connected to the electricity supply,
commissioned, operated and maintained by trained, qualified specialists authorized to perform such
work by the facility's owner-operator. The specialist staff must have read and understood these
Operating Instructions and must follow the instructions they contain. The devices may not be
modified or repaired in any way.
These specifications also apply for the battery unit.
1.3
Operational safety
Applications
The WirelessHART Adapter meets the requirements of the EU guidelines for the various range of
applications envisaged for the device. The permitted operating conditions must be observed. See the
"Technical data" section on Page
Hazardous area
A hazardous-area version (Ex version) of the WirelessHART Adapter is available for use in hazardous
areas.
• The non-hazardous area version (non-Ex version) of the WirelessHART Adapter is only suitable
for use outside hazardous areas.
• Depending on the particular approval, the intrinsically-safe and dust ignition-proof versions of the
device can be deployed in the corresponding hazardous areas.
The field devices that are connected to the hazardous-area versions of the WirelessHART Adapter
must also be suitable for use in hazardous areas.
• If a WirelessHART Adapter has been used in a non-Ex system it may no longer be installed in an
Ex system. This is because of the risk that the protective circuits might have become overloaded
accidentally and then not work correctly in the Ex system.
Please note the following if you use components in hazardous areas:
• Make sure that the operating staff in charge of installing and maintaining the device are suitably
trained and qualified.
• Ensure that all the system components have the appropriate safety certificates.
• Heed information provided in the device safety certificates, and comply with local and national
regulations.
