8.0 Maintenance

8.1 General safety rules

8.2 Maintenance

Whatever the nature of the maintenance, it must be performed exclusively by specialized technical

personnel.

In the event of a fault or maintenance to the electrical system, before proceeding with any checks, the

panel must be disconnected from the mains power switch in the open position (O). Check the absence

of voltage with a Tester before any operation. Each element of the electrical panel, if it proves to be

faulty, must be replaced only with original parts.

If maintenance involves parts outside the panel, perform the following steps:

• Securely and safely isolate the panel power supply in one of the following ways:

– Turn the AK-RC 113 main switch OFF and padlock the front cover.

– Isolate the power supply upstream of our panel permanently, by tapping it to OFF.

• Put signals to indicate that the machine is under maintenance.

Before proceeding with maintenance operations, carry out the following safety instructions:

• The electrical panel must be disconnected from the power supply.

• Prevent unauthorized personnel from being present in the intervention area.

• Put signals to indicate that the machine is under maintenance.

• Wear work clothes (suits, gloves, shoes, headgear) suitable and free of free appendages.

• Remove, if worn, any object that can get caught in protruding parts of the electrical panel.

• Have accident prevention equipment and tools suitable for operations.

• Tools must be clean and degreased.

• Have available the technical documentation necessary to perform the maintenance intervention

(wiring diagrams, tables, drawings, etc.).

• At the end of the maintenance operations, remove all the residual materials and carefully clean the

panel.

NOTE: It's absolutely forbidden to accomodate additional parts inside the panel.

The manufacturer declines every responsibility if the points in this chapter are not observed.

Scheduled maintenance is necessary to guarantee the functionality of the electrical panel over time

and to prevent the deterioration of some elements from being a source of danger for people. It must

only be carried out by specialized technical personnel and in compliance with the general safety

regulations.
