Maretron ACM100 用户手册

 

•  Clean the unit with a soft cloth.  Do not use chemical cleaners as they may remove 

paint or markings or may corrode the ACM100 enclosure or seals. Do not use any 
cleaners containing acetone, as they will deteriorate the plastic enclosure. 

•  Ensure that the unit is mounted securely and cannot be moved relative to the mounting 

surface.  If the unit is loose, tighten the mounting screws.  

•  Check the security of the cable connected to the NMEA 2000

®

 connector, and tighten if 

necessary. 

•  Check the security of all of the current sensor connections and voltage sensor 

connections on the top of the unit and tighten if necessary.
