Table 4-3. Dc Conductor Sizing - Advanced Energy AE 3TL 600 Series Installation And Operation Manual

To Connect to the DC Input Terminals
1. Determine the appropriate size of the DC conductors using the following table.
Terminals are rated for the maximum wire size listed in the following table. An
electrician should determine the appropriate wire size for your installation.

Positive/negative (from multi-
string array)
2. Ensure that the DC disconnect switch is in the OFF position.
3. Open the connection box cover.
4. Check the polarity of the DC home runs at the connection point to ensure
proper polarity.

5. Route the PV array conductors through the conduit to the desired entry conduit
hub on the DC side on the bottom of the inverter connection box. For the 600
series, use separate feedthroughs for the DC1 and DC2 inputs.

6. Strip each DC conductor 20 mm (3/4").
7. Connect the DC positive and the DC negative conductors to the correct polarity
of the DC input terminal block.
Guide each stripped conductor into the appropriate screw terminal.

Conductor
The AE AE 3TL inverter is a transformerless unit. Do not connect the
unit with PV modules that require positive (+) or negative (-) polarity to
ground. Only the array or PV module frame may be grounded.
Use only UL listed rainproof or wet location hubs for entry into the
connection box.
DANGER:
Make sure the PV array polarity and voltage between the positive and
negative cables are correct before connecting the PV array cables to
the DC terminal block.
DANGER:
Assurez-vous que la polarité et le voltage des câbles positifs et
négatifs des piles PV sont corrects avant de brancher les câbles des
piles PV aux bornes CC.
