11. Preventive maintenance
The recommended preventive maintenance tasks must be carried out at least annually, except where otherwise
stated.
11.1. Safety conditions
You must consider the set of conditions listed below as minimum requirements.
Before opening the unit, you must remove the power (see Section "10. Combiner box - inverter
disconnection").
An open housing never implies an absence of voltage in the unit, so only qualified personnel may
access the unit, following the safe operation guidelines stipulated in this document.
Ingeteam accepts no liability for any damages caused by improper use of the unit. You must propose
in advance to Ingeteam any work carried out on any equipment which implies a modification of the
original electrical arrangements. These must be studied and approved by Ingeteam.
All the maintenance checks included here must be carried out with the machine stopped, under safe
conditions for handling, including those specified by the client for these types of operation.
When carrying out maintenance work on the unit, you must wear the personal protective equipment
specified in Section "Personal Protective Equipment (PPE)" of this document.
After completing the maintenance task, replace the front cover and secure it with the screws
supplied.
11.2. Condition of the housing
A visual check of the condition of the housing must be carried out, confirming the condition of the seals and the
cover, as well as the fixing of the units to their anchor points on the wall. In addition, you must check the condition
of the housing for dents or scratches that might degrade the housing or cause it to lose its protection classification.
If these types of defect are noticed, the affected parts must be repaired or replaced.
Check that there is no moisture inside the housing. If moisture exists, dry it before making electrical connections.
Check the correct fixing of the housing components to their corresponding anchoring points.
Check the door seal of the unit is in good condition.
