IMPORTANT: When mounting the inverter outside, use rain-tight or wet-
location conduit hubs that comply with the requirements in the Standard for Fittings
for Conduit and Outlet Boxes, UL 514B.
Terminal connections for the inverter are located inside the inverter on the circuit
board at the bottom of the cabinet. The AC and DC terminals accept wires up to 6
AWG.
CAUTION: The input and output circuits are isolated from the enclosure.
System grounding, when required by Sections 690-41, 690-42, and 690-43 of the
National Electric Code (NEC), ANSI/NFPA 70-1999, is the responsibility of the
installer.

2.3.2 Separation of Circuits
The lower part of the inverter circuit board is divided into three sections.
1. The left side is dedicated to the low voltage DC communications.
2. The center is dedicated to the AC.
3. The right side is dedicated to the DC.
Each section has two to three knockouts as shown in Figure 3. UL 1741 standard
requires a straight run of wire, with no loops or crossover to the other circuits
(sections) and low voltage versus high voltage in each section.
1. Left knockouts (up to the divider) are for low voltage communications only
(PVM1010).
2. Center knockouts are for AC.
3. Right knockouts are for DC.
