3.1Commissioning the inverter
Commissioning an installation requires certain switching operations to be performed. This type of work must always be undertaken by qualified, properly trained personnel. Failure to perform switching operations correctly can result in significant property damage and serious physical injury. The components described in this manual operate at hazardous voltages and currents. Proper precautions must be taken during the commissioning process. This manual describes only the manual process of switching the PV system on and off.
The system must be switched on and off manually in order to carry out performance tests and maintenance procedures.
CAUTION
The instructions and guidelines relating to operation and control of the installation contained in the operating manuals for the switching equipment and other devices described here must be adhered to.
3.1.1Instructions and safety information
In accordance with the relevant standards and legislation (e.g. DIN VDE 0105), properly trained specialists must always be employed to operate and control electrical equipment.
All employees authorized to undertake switching tasks must receive instruction in accordance with the relevant standards and legislation (in Germany, at least once annually in accordance with BGV A1 §4 (Institute for Statutory Accident Insurance and Prevention/Instruction of Insured Persons)).
Follow all safety guidelines and work instructions stipulated by the relevant legislation and standards. Never take any action which would endanger either yourself or others.
The five safety rules in Germany:
1.Isolate from power supply
2.Provide a safeguard to prevent unintentional reclosing
3.Make sure that the equipment is
4.Ground and short
5.Cover or place guards around adjacent live parts
CAUTION
The safety rules (for example, DIN VDE 0105 – 100 § 6.2 in Germany) are especially applicable to switching or voltage disconnection operations.
If you are working abroad, you must adhere to the relevant local safety rules. Always pay particular care and attention when working on or around electrical equipment.
