2.1 Precautions on installation

Warning

Ensure to turn the power supply off before beginning removal or reinstallation of the equipment in order to prevent

an electric shock or equipment failure.

★ Ambient temperature and humidity (the equipment to be used in the specified range as listed below)

(1) Temperature range: 0 - 50 °C

(2) Humidity range: 20 - 90% PH (no dew condensation allowed)

(3) Installation gradient: Base plane ± 10 degrees

★ Do not install the equipment in the following places.

(1) Where temperature abruptly changes to generate dew

(2) Where corrosive or flammable gases are generated

(3) Where water, oil, steam or chemicals are received

(4) Where vibration or noise is directly applied

(5) Where dusty or salty ambience, or many iron scraps is present

(6) Where direct sunlight is received

(7) Where circuits may negatively be affected by static electricity, noise or magnetism

(8) Where direct warm or cool air is received from an air-conditioner

★ Precautions on installation

(1) Provide sufficient space for ventilation so that the ambient temperature does not rise to 50 °C or

higher. In case that the temperature of 50 °C or higher is suspected, use a fan or air-conditioner to

cool the ambience.

Take care that no cold air flows directly on the equipment.

(2) Do not install the equipment on a device that may generate large heat, such as heater and

transformer.

(3) Install the equipment away as much distant as possible from high-voltage devices, power lines or

power equipment.

(4) Do not block off the ventilation opening on the equipment. Ensure a sufficient gap between

stacked units of equipment.
