Summary
The YRO Modular level RSD DC 24V Series Overview is designed to be installed at solar panel level and providessafety shutdown of the DC supply to ZERO VOLTS in case of emergency.Shutdown is initiated in 3 ways -ManualOperation,AC Supply Cut-Off or Temperature Rise Trigger as follows:
YRSD-1P 1-to-1 wiring
Not: For NEC 2017 /2010 compliance PV panels should be <40v for 2-to-1 wiringand > =40v for 1-to-1 wiring (For YRSD -1P)
YRSD-2P 2-to-1 wiring
