Checking for Corrosion and Performing the Required Maintenance
IM 12J05S01-01E
Normally, it is sufficient to inspect the DOX10 power supply unit during periodic
system repairs (once a year or every two years), as fan as it works without fail. Daily
inspection and maintenance are not required.
Remove the cover of the terminal box and check for moisture. If the inside is very
damp, use a hair drier to dry the inside of the box.
Check that corrosive gas has not entered the terminal box and corroded the terminals
and conductors. If the corrosion is excessive and problems such as poor contact and
disconnection seem likely, replace the corroded apparatus.
