Temperature is indoor temperature. Humidity: 40-80%, non-condensation, with dehumidifier. Power supply: 220V / 50Hz. Fluctuation: within ±5%power grid grounding wire meets international requirement.Electronic automatic voltage stabilization and current stabilization devices should be installed in area where the voltage amplitude is more than 5%.
There shall be no strong electromagnetic signal interference nearby, and avoid any radio stations (or relay stations) around the installation site. Air pressure: ≥0,6mpa Some times, there should be anti-static floor, to enhance shielding
