4 MAINTENANCE
IMPORTANT NOTE
If any power supply is suspected of being faulty, return it to Eaton’s MTL product line, or the representative
from whom it was purchased, for repair or replacement. DO NOT make repairs or modifications. The
safe operation of the unit, and hence the safety of the site, can be affected by unauthorised changes.
Tests and maintenance checks should be limited to those described in this and the Testing section.
4 .1 ROUTINE MAINTENANCE
Check the general condition of the installation occasionally to make sure that no deterioration has
occurred. At least once every two years (and more frequently for particularly harsh environments), check
that:
a) power supplies are of the types specified in the relevant documentation;
b) power supplies and connectors are correctly and legibly tagged, connectors are plugged into the
corresponding power supplies and tag details comply with the relevant documentation;
c) power supplies are securely clipped to the DIN rail;
d) all cable connections are properly made to the plugs;
e) all plugs are fully inserted;
f) all connecting cables are of the specified type and rating; are
correctly routed and segregated
(particularly when fitted in enclosures) and are not frayed or otherwise damaged;
g) all cable screens are properly earthed;
h) there is no sign of damage or corrosion.
If the outer case of a FISCO unit requires cleaning, use a cloth dampened with a dilute mixture of
detergent and water. Special care should be taken to ensure that no liquid or debris enters the unit via
the ventilation slots.
4 .2 ENCLOSURES
The only maintenance needed for enclosures is cleaning and periodic visual inspections. Clean external
surfaces only, using soap and water; do not use chemical solvents or proprietary cleaning fluids.
Every year, or more frequently in harsh environments, inspect enclosures and check that they are
mounted securely and show no signs of damage that would impair their performance.
Remove any accumulation of water inside (using the drain plug, if fitted). Check cable gland nuts are still
tight and that all connections are properly made.
