This guide for use by qualified installers only
AC wiring must be sized appropriately to carry full load current on the
input and output AC circuits in accordance with the electrical codes or
regulations applicable to your installation. Table 1-4 is based on the U.S.
National Electrical Code, 2003 Ed. and the Canadian Electrical Code,
assuming 2-conductor-plus-ground cable, using 75 °C wiring, at an
ambient temperature of 30 °C. Other codes and regulations may be
applicable to your installation.
There are two knockouts on the front panel for AC input and output
wiring. Use the supplied strain relief clamps to prevent damage to the
wiring from tension being applied.
When making the AC input and AC output connections, observe the
correct color code for the appropriate AC wire, as described in Table 1-5.
AC Input Connections
1. Ensure that AC and DC power are both OFF.
2. Install the required circuit breaker in the AC output panel supplying
the unit (See Figure 1-6 on page 1–22).
3. Remove the screws securing the GFCI AC receptacle and remove it
from the front panel.
4. Disconnect the GFCI wiring, if desired.
