Note
This illustration shows the terminal block barriers and terminal block guards attached.
Warning
Power supply captive installation screws must be tight to ensure protective grounding continuity.
Note
For proper 2700 W DC-input redundant power configuration, all two pairs of input wires for one 2700W
DC-input power supply must come from the same battery system (A feed); all two pairs of input wires
for the other 2700 W DC-input power supply must come from another battery system (B feed).
Note
For multiple DC input power supply, each DC input must be protected by dedicated circuit breaker or
fuse. The circuit breaker or fuse should be sized according to the power supply input rating and local or
national electrical code requirements.
