2.1 Safety Precautions in Installation
1. Before any other connection is made, the protective earth terminal shall be connected to a
protective conductor. The mains (supply voltage) wiring must be terminated within the
connector in such a way that, should it slip in the cable clamp, the Earth wire would be the
last wire to become disconnected.
The protective conductor terminal is marked with a label on the product bearing the following
Symbol:
To connect the protective conductor terminal to earth, complete these steps:
1) Use a spade lug to make contact with the metal surface of the 40005E.
2) Use a green and yellow wire to reliably earth the protective conductor terminal. Wire gauge
must be no thinner than the current-carrying wire in the product
‟s mains supply.
3) Resistance between the protective conductor terminal and earth must be no greater than
0.1 ohms. Use thicker gauge wire if the resistance is too high.
2. Do not use this instrument in areas under hazardous conditions such as excessive shock,
vibration, dirt, moisture, corrosive gases or oil. The ambient temperature of the areas should
not exceed the maximum rating specified.
3. To minimize the possibility of fire or shock hazards, do not expose this instrument to rain or
excessive moisture.
