Decommissioning
10.1
Special personnel qualification required for decommissioning
Decommissioning may only be performed by specially qualified personnel in
accordance with the safety instructions.
All work on electrical equipment and electrical connection work may only ever
be carried out by trained electrical personnel in accordance with the wiring
diagrams in these installation instructions.
Also see the section on ”Personnel qualification”.
10.2
Safety instructions for decommissioning
To prevent damage to property and/or life-threatening injury to personnel
always observe the following:
D
Observe local regulations and safety requirements (NEC, UL or CSA, etc.)!
D
Warning mains voltage!
D
Before any work is performed on conductive components or lines the
electricity must be switched off and secured against being switched back on
again.
D
Whenever any unavoidable work is carried out on live components (eg:
testing to locate a fault), a second person must be present who can
disconnect/interrupt the power supply in the event of an emergency.
D
All of the steps involved in the decommissioning work must be worked
through in the order specified.
D
First of all, make the operating area for decommissioning completely safe.
Also read the chapter on ”Safety”.
Electrical hazards:
D
When working on the power supply, there is an electrical risk:
- from direct contact with live parts or parts which have become live
because of a fault
- from electrostatic processes
- from high voltage
- from short circuits/overloads as well as the risk of molten particles being
thrown out
Hazards caused by residual energies:
D
Note that, even after the product has been switched off or has stopped, there
may still be various forms of energy present, for example:
- in live electricity lines (from accumulators, capacitors, etc.)
