for handling, including those specified by the client for these types of operation.

Ingeteam accepts no liability for any damages caused by improper use of the equipment. 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.
15.2. Condition of the housing
A periodic 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 and the absence of 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 the correct fixing of the housing components to their corresponding anchoring points.
15.3. Condition of cables and terminals
You must perform an annual inspection of the cable and terminals conditions:
• 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 color of the insulation and terminals.
• Check that the connections have the correct tightening torque.
