3. Reason of delay schedule.
No comment.
4. Comment about the quality of installation.
Ingeteam has requested contractor and Chau Thon to connect the grounding cables for
installed cabinets to the grounding system, and measured the grounding system’s resistance
to ensure the safety.
5. HSE.
No comment.
6. Conclusion.
Up to now, the installation schedule for the Ingeteam’s equipment and cables is OK.
