Chapter 4: Connecting the AC and the Strings
to the Safety Switch

The Safety Switch disconnects all ungrounded DC conductors of the circuit to which it

is connected in compliance with the National Electric Code, and specifically NEC690.35,

which addresses ungrounded PV arrays. The Safety Switch is rated to the maximum

operating conditions of the inverter.

NOTE

For systems with an integrated production and export/import
meter:
To install and activate the export/import metering function,
refer to the document:

and-export-import-meter-na.pdf
