Protection
• When working on the system (e.g., during maintenance), protect the Facility part in
question from accidental or unauthorized restart.

2.3 Mechanical Safety

• Before start-up, check the product for any damage that may have occurred during ship-
ping. Do not put the product into operation if there is any mechanical damage.
• Do not open the product housing.
