Load-break switch and cable protection
NOTICE
Damage to the charging station due to the use of screw-type fuses as load-break switches
Screw-type fuses (e.g. DIAZED fuse or NEOZED fuse) are not load-break switches.
- Do not use screw-type fuses as load-break switches.
- Use a load-break switch or circuit breaker as a load disconnection unit (for information and design examples, see the Technical Information "Miniature circuit breaker" at www.SMA-Solar.com).
In systems with multiple charging stations, protect each charging station with a separate circuit breaker. Make sure to observe the maximum permissible fuse protection ( > Technical Data). This will prevent residual voltage from being present at the corresponding cable after disconnection.
LoLoads installed between the charging station and the circuit breaker must be fused separately.
The overcurrent protective device for the AC output circuit is to be provided by others.
