Installing the AC/DC Safety Switch

What is the AC/DC Safety Switch?
The AC/DC Safety Switch is a manually operated switch for disconnecting the
AC and DC power of a SolarEdge inverter in a SolarEdge power harvesting
system.
The AC/DC Safety Switch is installed on the bottom of each inverter. AC and DC
cables run through it and connect to the inverter.
The AC/DC Safety Switch opens all ungrounded 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 AC/DC
Safety Switch is rated to the operating condition of the inverter (32ADC,
600VDC and 25 continuous AAC 277/240/208VAC).
Two types of switches are available, one with part number DCD-1ph-US-A and
the other with part number DCD-1ph-US-B. The specifications for each of these
two switches are described on page 52. Both safety switches have similar
functionality and installation methods.
