Note:

This button must be used with the EI Inverter for NEC article 690.12 rapid shutdown compliance. It simultaneously forces the EI Inverter and TS4s into rapid shutdown, turns off the EI Battery, and stops a generator connected to the EI 200A Automatic Transfer Switch with Generator Support.

This button complies with option 3 of the NEC 690.12(C) requirements for rapid shutdown initiators:

For a single PV system, the rapid shutdown initiation shall occur by the operation of any single initiation device. Devices shall consist of at least one or more of the following:

(1) Service disconnecting means

(2) PV system disconnecting means

(3) Readily accessible switch that plainly indicates whether it is in the "off" or "on" position

Installation

Step 1 Open the cover of the RSD button by unscrewing the 4 retaining screws.
