To wire the inverter’s AC terminal block (top of Figure 7):
11. Route the fi lter box’s AC input/output wiring through the appropriate
knockouts/strain reliefs on the inverter, and then connect to the inverter’s
AC terminal block.
•
Connect wire A (white w/ black stripe) to Terminal #1 (AC NEUT OUT).
• Connect wire B (blue) to Terminal #2 (AC HOT OUT).
• Connect wire C (black) to Terminal #3 (AC HOT IN).
• Connect wire D (white) to Terminal #4 (AC NEUT IN).
Tighten all to a maximum torque of 3.6 N-m (32 in lbf).
To wire the fi lter box’s AC terminal block (bottom of Figure 7):
12. Route the AC input source/output load wiring through the appropriate
knockouts/strain reliefs on the fi lter box, and then connect to the fi lter
box’s AC terminal block.
•
Connect wire F (brown) to Terminal #1 (INV HOT OUT), and then
route and connect to the sub-panel.
• Connect wire G (blue) to Terminal #2 (INV NEUT OUT), and then
route and connect to the sub-panel.
• Connect wire H (blue) to Terminal #3 (INV NEUT IN), and then route
and connect to the main panel.
• Connect wire I (brown) to Terminal #4 (INV HOT IN), and then route
and connect to the main panel.
Tighten all to within a minimum/maximum torque of 1.2 N-m (10.6 in
lbf)/1.5 N-m (13.3 in lbf) – using a 3/16” (4.8 mm or less) fl at-bladed
screwdriver.
Note: The AC input source, output load, and grounds ( i.e., brown, blue,
and green with yellow stripe wires) are fi eld wires and must be provided
by the installer.
Info: Approved wire sizes for the MS-CEFB’s AC terminal block are
0.5-16 mm² (#20-6 AWG).
To wire the AC input/output grounds (bottom left of Figure 7):
13. Connect an AC ground wire from one of the fi lter box’s ground terminals
to the main panel’s ground busbar.
14. Connect another AC ground wire from the fi lter box’s other ground
terminal to the sub-panel’s ground busbar. Tighten both grounds to a
maximum torque of 5.1 N-m (45 in lbf).
Info: Approved wire sizes for the MS-CEFB’s ground terminals are
2 -33.6 mm² (#14-2 AWG) copper stranded.
To inspect the AC wiring:
1. Verify all wire runs are secured.
2. Verify strain reliefs or grommets are in place to prevent damage to the
wiring or conduit where it passes through walls or other openings.
3. Verify that all AC connections are correct, and all inverter and fi lter box
AC terminal screws are properly torqued.
4. Replace the inverter’s AC wiring access cover.
