MAINTENANCE

Note:

Limit tests and routine maintenance to those described in this

section and section 4. Return any isolator identified as faulty to the MTL
group company or representative from which it was purchased, for
repair or replacement.

7.1

Routine maintenance

Occasionally check the general condition of the installation to make sure
that no deterioration has occurred. At least once every two years (and
more frequently for particularly harsh environments), check that:

◆

isolators are of the types specified in the relevant documentation;

◆

isolators and connectors are correctly and legibly tagged,
connectors are plugged into the corresponding isolators and tag
details given comply with the relevant documentation;

◆

isolators are securely clipped to the DIN rail;

◆

all cable connections are properly made to the plugs;

◆

all plugs are fully inserted;

◆

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;

◆

all cable screens are properly earthed;

◆

there is no sign of damage or corrosion.

7.2

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
(more frequently in harsh environments), inspect enclosures and check
that:

◆

they are attached securely to their mountings;

◆

any accumulation of water inside has been removed (using the
drain plug, if fitted);

◆

cable gland nuts are tight;

◆

there are no signs of any damage;

◆

all connections are properly made.

WARNING

If an isolator is faulty, DO NOT make repairs or
modifications as these may affect the intrinsic safety of
the unit.
