Replacement of the «electronics block»
The principal electronic cards of the inverter (control card, power card, IGBTs etc)
constitue the basic equipment block and are grouped together in a stainless steel
cabinet called the «electronics block»
In the event of an equipment failure requiring the replacement of the above mentioned
«electronics block» please proceed as indicated below.
The electronics block is heavy. We would advise handling by two people or with
mechanical assistance.
It is compulsory to use protective gloves when handling the block.
- Dielectric gloves adapted to the operating voltage.
- Gloves to protect against mechanical hazards
- Authorised safety glasses to protect against electrical hazards
- Safety footwear
- Helmet
The necessary tools to replace the electronics block are:
- star screwdriver for lateral screws.
- plane screwdriver for terminal block connectors.
Proceed as follows:
Disconnect the equipment from the power grid and PV array.
Wait 10 mintues for the internal capacitance to discharge.
Check that there are no live voltages inside the equipment.
Open the equipment door.
Remove electronic block protections.
Disconnect the «DC bus» power cables in the block (XPV).
Disconnect the «AC input» power cables in the block (XAC).
Disconnect the cables in the terminal block from outside the equipment (X1, X2,
X3, X4, XDC).
Disconnect the display flat cable.
Unscrew the four anchoring points.
Slide it out to the side
Extract it.
To connect a new Electronics Block, follow the same steps in inverse order.
