This section covers the power supply removal and installation procedures for the 4000 W DC-input
power supply and is divided into the following topics:

For proper 4000 W DC-input redundant power configurations, all of the source DC for one 4000 W
Note
DC-input power supply must come from the same battery system (A feed); all of the source DC for the
other 4000 W DC-input power supply must come from another battery system (B feed).
The 4000 W DC-input power supply can operate at either 2700 W or at 4000 W. If you want to operate
the power supply at 2700 W, you need to connect two pairs of source DC cables to the VE-1 and the
VE-2 posts on the power supply terminal block. If you want to operate the power supply at 4000 W, you
need to connect a third pair of source DC cables to the VE-3 terminal block posts.
For multiple DC-input power supplies, each DC input must be protected by a dedicated circuit breaker
Note
or a fuse. The circuit breaker or fuse must be sized according to the power supply input rating and the
local or national electrical code requirements.
