5-1 Precautions for installation
The JW300 is not designed for dust and waterproof construction. Therefore, install JW300 in an enclosed
panel.
Avoid keeping the JW300 in the following conditions:
1. Ambient temperature extremes outside the range of 0 to 55 °C
2. The relative humidity exceeding the range of 35 to 90%
3. Sudden temperature changes, which may cause condensation.
4. Corrosive and flammable gases.
5. Water, oil and organic solvents dripping positions.
6. Dusts, iron and salty conditions.
7. A box in which high voltage device is installed.
8. Strong vibration and shock may usually occur.
Install on a good conductivity metal plated panel instead of painted one for easy grounding and better
noise tolerance. Use zinc plated retention screws of M5 for installing JW300.
