Follow Our Step-By-Step Guide

Featuring a plug-and-play design and utilizing MC4 cables, BENY’s RSD device offers effortless and streamlined installation, simplifying the setup process.

Decide which location to install your RSD.  You can install RSD horizontally or vertically, depending on your preference.

Remember to ensure the power line is off and wear PPE (personal protective equipment) insulated.

When you’re ready to wire the RSD input and output, make sure that the equipment grounding conductor (EGC) from the array is linked in the inverter. The EGC should connect the inverter and array for the inverter’s ground fault protection to operate.

Look for the input wires on the side of RSD marked as “Input” and connect them to the PV array. The positive end of the PV array should be connected to the +RSD input wire, while the negative end of the PV array must be linked to the -RSD input wire. 

Then look for the output wires. Connect the RSD output wires to the inverter inputs. The +RSD output wire must be linked to the positive DC input terminal, and the -RSD output wire must be connected to the negative DC input terminal.

Install the 24V power supply. Open the PV system AC disconnect switch and the PV breaker first to make sure the inverter is disconnected from the grid. Note that the power supply of RSD should be connected to a 2-wire 208V line-to-line or 3-wire 240V line-to-line inverter output.

For multiple RSD installations, simply repeat the wiring steps to connect the second RSD control circuit to the second output position on the power supply.

Within the ten-foot perimeter of the PV array, DC voltage must be lowered to no more than 30Vdc, and power to <240VA, within 30 seconds. This is to comply with NEC 690.12 rapid shutdown requirements.

When the PV system has been installed, test the RSD system. Check if the inverter DC input drops to less than 30 Vdc within 30 seconds after AC is removed. If it is, then your RSD installation is a success.
