Protect PV.630 Operating Instructions
∙All necessary operational measures must be initiated prior to deactivating any safety device in order to perform mainte- nance, repair or any other work on the unit.
Safety awareness also entails informing colleagues of any unsuit- able behaviour and reporting any faults detected to the appropriate authority or person.
The member of personnel responsible for the equipment must ensure that:
∙The safety instructions and operating instructions are readily available and are complied with
∙The operating conditions and technical data are observed
∙Safety devices are used
∙The prescribed maintenance work is performed
∙Maintenance personnel are informed without delay or the equipment is shut down immediately in the event of abnormal voltages or noise, high temperatures, vibrations or any similar phenomena, so that the cause of this can be determined
2.5Particular Dangers associated with Photovoltaic Systems
Here you will find information about the additional dangers associ- ated with photovoltaic systems.
An active power source is connected. Depending on the operating status, the PV cells and the equipment may be live.
DANGER
Contact with voltage! Extremely high DC voltages of up to 1000 VDC are present.
Risk to life due to electric shock.
Do not touch live parts.
Wear personal protective equipment ( Chapter 2.2.3).
Crystalline silicon cells
Crystalline PV cells (silicon cells) usually have an IT system configuration, i.e. a
A generator with a complex branched structure can only be shut down with a great deal of difficulty (in the event of a short circuit, for example).
Thin-film cells
To prevent corrosion,
Lightning protection
The desired level of protection can only be achieved if a lightning protection zone concept has been implemented for the building where the unit is to be installed, in accordance with DIN VDE
