The 4000 W DC-input power supply requires two source
DC-inputs to be connected; it cannot operate with only one
positive (+)/negative (-) source DC terminal pair installed.
For multiple DC input power supplies, each DC input must be
protected by a dedicated circuit breaker or a fuse. The circuit
breaker or the fuse must be sized according to the power supply
input power rating and any local or national electrical code
requirements.
The 4000 W power supply cannot operate with only one source
DC-input connected.
The 4000 W power supply cannot operate with only one source
DC-input connected.
