Safety Notes and Precautions
1. The protective earth terminal should be connected first before any other connection is made.
To avoid making the recorder dangerous under fault conditions, any interruption of the
protective Earth conductor inside or outside the recorder is prohibited. Even in the case of a
portable unit, the protective earth terminal must remain connected if the recorder is connected
to any hazardous voltage.
2. Keep signal and supply voltage wiring separated from one another. If this is impractical, use
shielded cables for signal wiring. Double insulation should be used for signal wiring when the
recorder is being used with hazardous voltage.
3. Do not use the recorder where there is high vibration, or high magnetic field, this could cause
damage or error of measurement.
4. All maintenance or repairs should be carried out with power disconnected, to avoid personal
injury, or damage to the unit.
5. In areas with conductive pollution, adequate ventilation, filtering and sealing need to be
installed.
