REAL TIME CLOCK START UP INSTRUCTIONS document provides instructions and procedures for and starting up the Micronik 200 R7426A B C No special tools are required for mounting and The user interface and liquid crystal display allow and easy parameter setting and output adjustment INSTALLATION NOTE Visually inspect equipment for shipping damage any damage to the appropriate Honeywell Refer to job drawings for specific installation and mounting location Verify the controllers will be adequately separated the main power supply relays or other equip which can possibly generate electromagnetic Verify that the ambient temperature and the humidity the controllers will not exceed 0 50 32 122 5 to 95 rh Use shielded wiring in areas with high EMI All wiring should be separated from power lines by at 150 mm 6 Do not install controllers near frequency converters other high frequency sources controllers can be mounted in an electric cabinet or other enclosure They are suitable for back panel DIN rail or front panel mounting The corresponding mounting as well as dimensions and panel cut out are in the mounting instruction sheet EN1B 0202GE51 with the controllers the compensation sensor signal T3 is received from controller parallel connection of compensation inputs the jumper W303 has to be cut before the controller see Fig 2 This disconnects the from the internal power supply 2007
