Wiring diagram



● Protection and Isolation 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 Isolation wiring
● The load should be ≤ DC 1000V
The Negative pole (-) could be earthed,butin both cases
the breaker protects and isolates the load
