19. SERVICE

CAUTION: There are no user-replaceable parts inside the

Wiring Diagram
The following diagram shows how the distribution box is electrically
connected to the hybrid inverter. When replacing breakers or wires on
the distribution box the following rules must be observed: (1) All AC
breakers must be sized for 40A or less, and (2) All wiring must be sized
for 40A or more.
NOTES: EverVolt has L1 and L2 connections for two AC input sources,
although it can only accept one source at a time. The inverter has
separate neutral connections for grid input, generator input and output.
These are electrically common. The distribution box is both an input
conduit box and an AC load center. The distribution box also contains
maintenance transfer switches (load selection breaker). Maintenance
transfer switching assemblies allows for the inverter to be taken offline
if necessary without shutting the entire system down. These assemblies
include an interlock mechanism that isolates the AC Lines from each
other.
