Wiring diagram

●Protection and lsolation wiring

●The load should be≤DC1000V
The connection considered for anetwork in which the middle point of the supply source is earthed, In this case the breaker protects and isolates the load

●Protection and lsolation wiring

●The load should be≤DC1000V
The Negative pole (-) could be earthed,but in both cases the breaker protects and isolates the load
