Cleaning
The MA 2/4Port Node only requires minor attention. Clean the surface only with dry soft cloth. Do
not use any liquid cleaner or compressed air. Do not use any solvent. Check ventilation holes are
clear.
Depending on the environment we recommend to clean the device professionally every 2 – 5 years.
Maintenance
The Unit requires no regular maintenance, so it is not necessary to open the unit. The unit should be
serviced by qualified personnel only, as live parts may be exposed when opening and/or removing
coverings.
