indicated.
CAUTION
Maintenance operations must be carried out by qualified personnel. There is an electrical shock
hazard.

in safe handling conditions.
CAUTION
When accessing the various compartments, attention should be paid to the safety recommendations
provided in chapter "4. Safety instructions".
7.1. Maintenance tasks
Check the housing condition
A visual inspection should be made of the housing condition, checking the condition of the seals, and cover. A
check should also be made to ensure that the equipment is firmly secured to the wall and also to the transformer, if
present. Likewise, the housing should be checked for knocks or scratches which could degrade the cabinet and lower
its Protection Rating. Should any defects of this nature be observed, then the parts affected should be repaired or
replaced.
Check the condition of the cables and terminals
•
Check that the cables are laid correctly in order to ensure that they are not in contact with live parts.
•
Check the insulation for damage and hot points, inspecting the colour of the insulation and terminals.
•
Visually check that the connections are firmly secured.
Check that there is no humidity in the cabinet interior
If moisture is detected, it is essential to dry it up before making the electrical connections.
Check the cabinet anchors
Check that the cabinet components are correctly secured to their corresponding anchors.
Check that the unit is correctly ventilated
To do so:
•
Check the condition of the air extraction fans and clean and replace if necessary.
•
Clean the radiator fins.
•
Clean the ventilation grids.
Check the characteristics of the surroundings to ensure that the buzzing noise is not amplified or transmitted.
Install the equipment in a place that is easily accessible for installation and maintenance work and which offers suffi-
cient space for personnel to operate the keypad, read the display and access the inverter interior.
