Training
Furthermore, Eaton can provide training courses for
Magnefix users' technical staff.
Maintenance kit
The maintenance kit is intended for maintaining Magnefix
switchgear. This maintenance kit contains special tools.
MAC-05 conditioning fluid
Magnefix MAC-05 conditioning fluid may be used to
remove sticky dirt and to apply a fresh moisture-repellent
film. The fluid is a solution of silicone oil in water, which is
sparingly applied to the parts to be treated, using a wet,
lint-free cloth. When the fluid has dried, the surface is
rubbed with a dry cloth to obtain a polished appearance.
MAC-05:

is non-inflammable;

does not present any hazards to users
(provided it is not swallowed)

does not contain any volatiles which may be harmful
to people and the environment;

does not attack the surface of parts
treated with it.
When used as a cleaning agent, MAC-05 is not suitable for
dealing with heavy oil or grease contamination or chemical
contaminants. MAC-05 can always be used as a
conditioner for clean or cleaned surfaces.

6.3 Cleaning

The fixed portion of the switchgear, the interior and exterior

C
AUTION
Be aware of feedback from the low-voltage side of
transformers.
2. Fit the protective earthing.
3. Remove loose dirt (using compressed air or a dry
hand brush).

We advise against scouring thermoplastic
components. Replace these components, if they
are heavily attacked.
8. Remove any tracking marks using a scouring pad,
scraper or end mill cutter.
9. Dry the switchgear using a clean lint-free cloth.
10. Blow the switchgear clean on the inside.

conditioning fluid on the clean and dry surfaces. Rub
this film until a polished, non-sticky, moisture-repellent
finish is obtained.
N
OTE
Make sure the protective film stays very thin so
that it will not become sticky. Excessive MAC-05
retains dirt.
