Power module
A rechargeable Lithium-Ion power module powers the Trex unit. A typical charge should
last for more than 8 hours of continuous use. The Trex unit displays a low-battery warning
when the remaining charge reaches a set level. Ensure you save any unsent data for a
device before the power module reaches a low level.
You do not need to discharge or calibrate the power module. Contact technical support if
you experience any problems with the power module.
WARNING
Do not install, remove, or charge the Lithium Ion (Li-Ion) power module in a hazardous
area environment.
Precautions for the power module and AC adapter
Understand and follow the precautions below before using the power module or AC
adapter.
• When transporting a Lithium-Ion power module, follow all applicable regulations.
• Ensure sufficient grounding. Ensure the personnel, working surfaces, and packaging
are sufficiently grounded when handling electrostatically sensitive parts.
• Avoid touching the pins on the connectors or components. Discharged energy can
affect the power modules.
• Protect the power module and AC adapter from moisture, and respect operating and
storage temperature limits listed in the AMS Trex Device Communicator User Guide. The
AC adapter is for indoor use only.
• Do not cover the power module or AC adapter while charging. Do not subject them to
prolonged periods of direct sunlight, or place them on or next to heat-sensitive
materials.
• Charge the power module with only the provided AC adapter. The AC adapter should
not be used with other products. Failure to comply may permanently damage the Trex
unit and void the IS approval and warranty.
• Do not open or modify the power module or AC adapter. There are no user-serviceable
components or safety elements inside. Opening or modifying them will void the
warranty and could cause personal harm.
• Clean the AC adapter by clearing the terminal of dirt and debris, if required.
• If the AC adapter is used in a manner not specified by Emerson, the protection provided
by the equipment may be impaired.
• The AC adapter comes complete with interchangeable plug heads for UK, USA, EU and
AU.
• The maximum operating altitude for the AC adapter is 2000 meters.
