STANDARDSThe CDM 12.1 has been designed to comply with safety standardsof various countries. However, since its approval depends onthe application, this unit is not approved as a unit.It is prepared for the following standardsUL1270UL1409CSA C22.2 No. 1-M906. HANDLING INSTRUCTIONS- Storage in dusty, high temperature and high humidity envi ronments should be avoided.To avoid damage to the LOGU by electrostatic discharges,measuring equipment and operators sholld be grounded duringhandling.Contamination of the objective lens will influence theperformance. Avoid fingerprints on the lens, handle the mecha nism in a clean environment.The actuator with lightpath has been adjusted carefullyduring manufacturing. Avoid touching this part 11 Do notdisassemble or readjust 11- Please keep the short circuit clip on the flexfoil mountedas long as possible. Remove just before installing the CDM12.1 in his final application to avoid the risk of damage byelectrostatic discharges.- Fast heating up (e.g. by bringing the mechanism from a coldplace into a warm and humid room) can result in moisturecondensating on the lens, thus influencing the playability fora certain time. Before checking the performance the mechanismshould stabilize for at least 4 hours.Partllalll!laterla 1 facturerlR.-flleGradeGeneric .,Type 110.ID-llilrlLaser (LOGU)SharD LTOH30P2Mounting plateSayer AGE4161394VlPCMakro 10n8035Turntab le94V2MakrolonGeneral ElectricE45329Lexan 121RL ightpenHoechst Ce laneseE8300594VOLCPVectra A130Guide blockLMPE45195OFL 4044FlexfoilMltto OenkoE69892 M·AM-flexEl 32084- - Safety :people canlens.The laserbeam may damage the human eye.
