10. Maintenance operations
10.1. General information
Thanks to their simple design, fixed partss do not
require any particular maintenance except for the
"Periodic checks" in paragraph 9.
In order to avoid any hazardous deterioration of the
insulating level, it is advisable to perform the first
inspection six months after putting into service so as
to establish the routine check intervals and the
maintenance card.
Moreover, it is recommendable to follow the
instructions for the single items according to the
instruction manuals supplied with the apparatus.
It is advisable to keep a maintenance card and a
service book containing all the operations performed
along with date, description of possible anomalies,
reference to the data needed to identify the
apparatus (see chapter 2) etc.
For further information, refer to article 10 of the IEC
60694 Standards.
Should you have any problems, do not hesitate to
contact us.
The electrical apparatus is easily affected by ambient
conditions and can be damaged by abnormal service
conditions.
Dust, heat, humidity, corrosive atmosphere, chemical
residues, fumes, vibrations and other elements can
influence apparatus performances and the life of the
electrical apparatus.
Especially when combined, these conditions cause
premature faults.
The most important rules to follow are:
• keep clean;
• keep dry;
• tighten bolts and connections;
• preserve the mechanical parts from excessive
friction.
The instructions concerning the operations to be
carried out on the various parts of the module,
excluding the apparatus for which the relevant
instruction manuals should be referred to.
• Maintenance must be carried out either
by our personnel or by qualified skilled
personnel.
Should the customer's personnel be in
charge of maintenance, the customer is
responsible for any operation performed
on the apparatus.
• W hile performing routine checks and
maintenance operations, de-energise all
the components.
• T he spare parts shown in the table "List
of spare parts/accessories" can only
be replaced by our personnel. For the
apparatus, consult the relevant manuals.
• U se original spare parts only.
10.2. Metallic structure
This comprises the supporting construction
complete with vertical and horizontal segregating
sheets.
These parts are galvanised.
Galvanised components
The galvanised and passivated components can be
cleaned by means of a dry cloth.
Oil and grease can be removed using a cloth soaked
in a suitable solvent. To polish the surface, repeat the
previous operation.
10.3. Mechanical actuators
The mechanical actuators comprise all the
mechanical parts of the fixed part for carrying out
the operations, locks and safety devices. The force,
prevention and safety locks are all considered
mechanical actuators.
The moving components are lubricated and tested
while assembling the fixed part.
The mechanical interlocks must not be
ignored, but used properly so as to avoid
any hazardous situations.
The mechanical interlocks must reach the final
locked/ unlocked positions without any intermediate
stops.
They must be tested several times to check that they
operate perfectly. The operating force required must
also be checked.
Always make sure that the mechanical interlock
position corresponds with the position of both the
part controlled device and with the interlocked
apparatus.
If excessive force is required to activate the device it
means that the mechanism is prevented from
moving.
In this case, please contact us.
