Hauser
Battery unit
The WirelessHART Adapter is designed to power a field device. In the battery version, power is
supplied via a high-power lithium-thionyl chloride battery unit. This has implications for operational
safety and storage. Please refer to the hazardous materials regulations provided in the accompanying
Safety Data Sheet (CD-ROM folder:
Safety Data Sheet).
Maintenance
Warning!
• The housing of the WirelessHART Adapter may
not
be opened in hazardous areas if dust is
present. The battery unit can only be replaced in a dusty atmosphere if adequate ventilation
ensures the environment is free of dust.
• Any tampering with the antenna, electronics or battery unit invalidates Hauser’s
warranty along with the telecommunications approval and hazardous area approval.
The housing of the hazardous-area version may be opened in the presence of gases in hazardous
areas for the purpose of commissioning the device and replacing the power supply unit.
The housing may be opened outside hazardous areas for the purpose of commissioning the device
and replacing the power supply unit.
WirelessHART Adapters with an electronically controlled power supply unit do not require any
maintenance. In the case of WirelessHART Adapters with a battery unit, the battery unit is the only
component that may be replaced. The WirelessHART Adapter may not be repaired.
If the device is faulty or malfunctions, return the device to Hauser. Follow the instructions
outlined in the "Return" section on Page
98. In the case of devices with a battery unit, the battery
unit must be removed before the device is returned.
