GENERAL INSTRUCTIONSInstallation EnvironmentAvoid using the Micro−Imagechecker A210/A110 in the following types of locations:− Locations with direct sunlight or environmental temperatures that exceed a rangeof 0°C to 50°C.− Locations with a relative humidity exceeding a range of 35%RH to 75%RH or thatare subject to condensation due to dramatic temperature fluctuations.− Locations with an atmosphere containing corrosive gases or flammable gases.− Locations that subject the main unit to direct vibration or impact.− Locations with a lot of fine particles, iron filings or salt.− Locations likely to have contact with water, oil or chemicals.− Locations with an atmosphere likely to contain organic solvents such as benzine,paint thinner, and alcohol as well as strongly alkaline materials such as ammoniaand caustic soda.Static ElectricityIn a dry environment, there is a risk of accumulation of static electricity, so when thereis a need to touch the equipment, users should always discharge the accumulatedstatic by touching an earthed part of the equipment first.CleaningDo not use thinners or similar solvents, as they may dissolve parts of the unit andcause colors to run.PowerUse an insulated power source with built in protection circuits. The controller powerunit uses non−insulted circuits, so if an irregular voltage is applied, there is a dangerthat the internal circuitry will be damaged. If you use a power source that does not useprotection circuits, supply the power via a fuse or other protective device.Power Sequence− Arrange the power sequence so that the controller power source is turned offbefore the input/ output power source.− If you turn off the input/output power source before the controller power source,the controller unit will detect an input signal level change and may not runproperly.
