WARNING:
Essential load terminals are to be wired to a
separate subpanel. Never connect essential load lines
directly to the main service panel without use of an external
automatic transfer switch. Direct connection of essential
loads output to the grid will result in damage to the inverter.
WARNING:
Do not connect essential loads output in parallel
with the grid!
Connecting to the Essential Load
Step 1. Make sure the circuit breaker is off.
Step 2. For each AC wire, strip 15mm(0.6in) of isolation.
Step 3. Be sure to connect PE protective conductor first (GND).
Step 4. Connect the wires according to the labels indicated on the
terminal block or your grid utility type.
How to Install Conductors into the Terminal Blocks (Installation below shows
the grid connection for reference. Make sure to use proper terminal block,
connect grid to grid, PV to PV and Load to Load.)
