Figure 13. Battery LED indicator.
When the button located on the battery side is pushed, user can monitor the absolute state of charge
of the battery. Each LED represents 20 % of battery charge. If the battery state of charge is below or
equal to 10 %, the red LED blinks showing the user that battery should be recharged.
For more information regarding battery use, please refer to Appendix B: LI-ION BATTERIES GENERAL
USAGE INSTRUCTIONS and Appendix C: RECOMMENDATIONS TO THE END-USERS OF BATTERIES.

7.2.2. AC/DC PSU

A 120-watt AC/DC PSU is used to power the GT5000 Terra and to charge the battery. DC power
supply input is located on the side of the analyzer, behind the battery hatch. The required mains
input is from 100 VAC up to 240 VAC, 50 Hz- 60 Hz. Hold-up time of the analyzer is 20 ms from loss
of AC input.

7.2.3. Power Inlet

Only Gasmet AC/DC PSU is recommended for GT5000 Terra operation. AC/DC PSU should only be
used indoors. Note that the analyzer should not be operated in wet conditions when the battery
hatch is open.

inside the battery hatch.

7.2.4. Fuses

The AC/DC PSU has an internal resettable fuse. Any error condition will blow the internal fuse. The
fuse will automatically reset after the fault condition is corrected. If the AC/DC PSU is potentially
damage, please contact Gasmet before starting any maintenance.
Battery is overcharge, over discharge and over current protected in order to prevent possible damage
or potential explosion. The overcharge and over discharge protection by cell voltage control is
reversible; the fuse protecting against overcurrent is irreversible. Reversible protection of the battery
is reversed by applying +12V DC voltage on battery power supply pins (Pin 1: Batt- and Pin 2: Batt+).
