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.
