Preventive maintenance
16. Preventive maintenance
The recommended preventive maintenance tasks must be carried out at least ANNUALLY, except where otherwise
stated.
16.1. Safety conditions
Before opening the unit, you must remove the power (see Section "15. Shutting down the unit").
You must consider the set of conditions listed below as minimum requirements.
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 equipment. Any work
carried out on any equipment which implies a modification of the original electrical arrangements
must be proposed in advance to Ingeteam. 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, the Personal Protective Equipment specified in
Section "3.2. Personal Protective Equipment (PPE)" of this document must be worn.
After completing the maintenance task, replace the front cover and secure it with the bolts supplied.
16.2. 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
covers, as well as the fixing of the units to their anchor points. 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 you
notice these types of defect, the affected parts must be repaired or replaced.
Check that there is no moisture inside the housing. If moisture exists, you must dry it before making electrical
connections.
Check the correct fixing of the housing components to their corresponding anchoring points.
16.3. Condition of cables and terminals
•
Check the correct path of the cables so they do not come into contact with live parts.
•
Check the insulation deficiencies and hot spots by checking the colour of the insulation and terminals.
•
Check that the connections are properly adjusted.
