4.4. Safety precautions
4.4.1. Installation Location
The analyzer must be installed and operated in a dry and condensation-free place. The
environment should be clean enough so that no dirt will accumulate on or inside of analyzer.
The installation location must be preferably free of strong vibrations. Shocks during transport, for
example, can cause serious damage. When transporting the instrument, use the original wooden
box or transport case with original shock absorbing materials.
The equipment must not be operated in wet conditions when the battery hatch is open.
Locate the AC/DC PSU so that the appliance coupler of it is easily reachable. The socket outlet to
which the AC/DC PSU is connected shall be in vicinity of the equipment and easily reachable.
Disconnect the equipment from mains by mains plug from AC/DC PSU.
In some cases, large temperature changes may affect the analysis results and the accuracy of the
measurements decreases. If the sample gas temperature significantly differs from the temperature
the background was measured at, re-measuring the background improves the analysis.
4.4.2. Ventilation Requirements
Care should be taken in order to ensure a free convection airflow around the GT5000 Terra and avoid
fan obstruction when in long term operation with AC/DC PSU. Do not block fans air circulation. This
would decrease life expectancy of most of the internal components.
4.4.3. Protective Earthing Instructions
Precautions should be taken so that the protective earthing scheme on the analyzer is not defeated.
Never connect AC/DC PSU to an AC mains socket that has no protective earth. Use only certified
Power Supply Cord.
4.4.4. AC/DC PSU Connection
The AC/DC PSU must be connected to a power source with the AC voltage specified in this manual.
Do not use with an extension cord or receptacle unless all three blades can be fully inserted to
prevent blade exposure.
Connect the power supply cord to Gasmet AC/DC PSU that is equipped with an appliance inlet.
Use an uninterruptible power supply (UPS) if the electric power is subject to major disturbances or
power failures.
All cautions and warnings on the equipment must be noted. If the equipment is not in use for a long
time, disconnect it from the mains to avoid damage from transient over-voltage.
Please make sure that before connecting the AC/DC PSU to the analyzer or inserting the battery to
the analyzer that the manual power switch is in off position.
