10.10. Checking the relays, fuses and disconnect switches
DANGER
Electric shock and burns hazard: coming into contact with live PV field or grid
components can lead to serious injury and even death!
NEVER work on the equipment unless it is switched off and disconnected from the power
supply.
This section refers to relays, fuses and fuse holders/disconnect switches located inside the cabinet.
•
Visually inspect the installed fuses and the fixing springs on the fuse holders.
•
If necessary, grease the contact points on the holders.
•
Visually inspect the installed relays, checking that they fit well into their holders.
10.11. Checking the SPDs
DANGER
Electric shock and burns hazard: coming into contact with live PV field or grid
components can lead to serious injury and even death!
NEVER work on the equipment unless it is switched off and disconnected from the power
supply.
Inspect the state of the SPDs (Surge Protective Devices) by checking the status of the button/slot on the
discharger.
Each DC module is provided with one SPD and, if the
AC SPDs
option is present, one AC SPD is also
provided.
The exact position of the SPDs can be seen on the Electrical and Mechanical Diagram.
