Connecting to the AC Grid and to Backed-up Loads

Connecting to the AC Grid and to Backed-up Loads
Use a 6 mm² 3-wire cable. T he maximum wire size for the input terminal blocks is 10 mm².
NOTE
If there are multiple inverters in the installation, each inverter should be connected to a separate
backed-up loads panel. Do not share backup output between inverters.
NOTE
StorEdge inverters require neutral connection at all times (only grids with neutral connection are
supported).
To prepare the AC cables:
1. Turn OFF the AC before connecting the AC terminals.
WARNING!
If connecting equipment grounding wire, connect it before connecting the AC Line and Neutral
wires.
2. Strip 58 mm / 2.32'' of the external cable insulation and strip 8 mm / 0.32'' of the internal wire
insulation.
To connect the AC cables - StorEdge Connection Unit with glands:
1. Insert the cable through the appropriate cable gland:
For grid connection ( from the main distribution panel) and for grounding: insert through the

gland labeled AC1 GRID
For backed-up loads connection ( from a backed-up loads panel): insert through the gland labeled

AC2 BACKUP
2. Connect the AC wires according to the labels on the terminal blocks: Use a standard flat-blade
screwdriver to connect the wires to the spring-clamp terminals:
a. Insert the screwdriver into the square opening at the top of the terminal block a nd press to open
clamp mechanism.
b. Insert the wire into the round opening and release t he screwdriver to spring back and clamp the
wire.
3. Tighten the AC cable gland with a torque of 2.8-3.3 N*m / 2.0-2.4 lb*ft.
