  • Page 23: Installation

    INSTALLATION INSTALLATION PRECAUTIONS 1. Installation Environment 1) Do not expose the display directly to vapor or heat. Protect the unit from rain or water. 2) The display uses glass material, and cracks easily. So, do not subject it to vibration and shock.

  • Page 24: Installation Precautions

    2. Installation Precautions 1) The support must withstand the weight of the unit. The standards of the country must be met. 2) Special care should be taken in areas where earthquakes occur frequently. (At a magnitude of six, each pipe must withstand a load of 100 to 150 kg). 3) Grounding should be performed.
