4.1 Electrical Connections

The design intent of the PV Grid-tied Inverter and Integrated AC/DC

Disconnect unit is to provide a safe method of connecting the inverter to

the PV system array and the utility service source circuits. The AC/DC

Disconnect provides a single location for terminating AC, DC and ground

conductors.

In addition, the AC/DC Disconnect provides the following:

• An AC/DC ON/OFF disconnect switch to the PV array and the utility

service, and functions as a wire raceway.

• Is shipped with the inverter as an integrated assembly, housed indi-

vidually: an inverter and a disconnect.

• Allows an inverter to be removed for service while leaving the discon-

nect in place.

CAUTION

All electrical installations should be completed in accordance

with local electrical codes. The National Electrical Code (NEC)

requires that the inverter be connected to a dedicated circuit with

no other outlets or devices connected to the same circuit. See

NEC Section 690-64(b)(1). The NEC also places limitations on

the size of the inverter and the manner in which it is connected

to the utility grid. See NEC Section 690-64(b)(2). Please refer

to CSA 22.1 or your applicable electrical code if this product is

installed outside the United States.

To reduce the risk of re, connect the inverter to the appropriate

size breaker (see Table 4-2 for required branch circuit

protection). Maximum branch-circuit over-current protection

is calculated in accordance with the National Electrical Code

(NEC), ANSI/NFPA 70, CSA 22.1 or applicable local electrical

codes.

When exposed to light, photovoltaic (PV) arrays create

electrical energy that cause a hazardous condition. To avoid

this, completely cover the surface of all PV arrays with opaque

material before wiring them.

Only qualied electricians should make the connection between

the AC/DC Disconnect and the utility grid. The

AC/DC Disconnect contains no user-serviceable parts. Refer

maintenance to qualied service personnel.
