To make a permanent connection to existing AC wiring (continuing
from # 13 of “Step 4: Connecting the AC Input Wires” on page 1–15):
1. Ensure that AC and DC power are both OFF.
2. Install the required value of circuit breaker in the AC load panel (see
Figure 1-6 on page 1–21 and Figure 1-7 on page 1–22).
3. Remove the left-hand side AC wiring knockout from the front of the
unit.
4. Locate the terminal block.
The two output terminals are labeled as follows:
•AC Output (L)
•AC Output (N)
A separate screw is provided to connect the AC output ground.
5. Strip about 2 inches (50 mm) from the jacket of the AC output cable.
The AC output cable may be either solid or stranded (as required), but
must have three conductors and sized as in Table 1-4 on page 1–16.
(The AC terminal block accepts wire sizes up to No. 10 AWG.)
6. Strip approximately 3/8 inch (10 mm) off the insulation of each
conductor.
7. Remove the AC wiring compartment cover.
8. Run the AC cable through the left-hand side knockout and into the
wiring compartment.
9. Fasten the Ground wire to the grounding screw.
10. Using the 1/8 inch slot screwdriver, loosen the wire attachment
screws on the terminals.
WARNING: Shock, fire, and energy hazards
Make sure wiring is disconnected from all electrical sources before handling. All
wiring must be done in accordance with applicable local and national electrical
wiring codes. Do not connect the output leads of the inverter to any incoming AC
source.
Important:
The applicable installation code may not allow you to run the AC
IN and AC OUT wiring through the same AC knockout.
