Company Profile
WHEN THE PHOTOVOLTAIC ARRAY IS EXPOSED TO LIGHT, IT SUPPLIES A DC VOLTAGE TO THE
HY-RSD.
PLEASE READ THIS MANUAL BEFORE INSTALLATION. ANY DAMAGE TO THE PRODUCT DUE TO NOT
FOLLOWING THIS MANUAL IS NOT COVERED BY THE WARRANTEE.
ALL THE INSTALLATION SHOULD BE DONE BY CERTIFIED ELECTRICIAN.
BESIDES THE CABLE CONNECTORS, NOTHING INSIDE THE PRODUCT SHOULD BE MODIFIED.
ALL INSTALLATION SHOULD FOLLOW THE LOCAL ELECTRIC CODES. THIS PHOVOLTAIC RAPID
SHUTDOWN EQUIPMENT(PVRSE) DOES NOT PERFORM ALL OF THE FUNCTIONS OF A COMPLETE
PHOTOVOLTAIC RAPID SHUTDOWN SYSTEM (PVRSS). THIS PVRSE MUST BE INSTALLED WITH OTHER
EQUIPMENT TO FORM A COMPLETE PVRSS THAT MEETS THE REQUIREMENTS OF NEC (NFPA 70)
SECTION 690.12 FOR CONTROLLED CONDUCTORS OUTSIDE THE ARRAY. OTHER EQUIPMENT
INSTALLED IN OR ON THIS PV SYSTEM MAY ADVERSLY AFFECT THE OPERATION OF THE PVRSS.
IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE THAT THE COMPLETED PV SYSTEM
MEETS THE RAPID SHUTDOWN FUNCTIONAL REQUIREMENTS.
PLEASE CONTACT AUTHORIZED SERVICE AGENTS FOR ANY SERVICE WORK.

4. Installation
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance may void the user’s
authority to operate the equipment.
Mount HY-RSD on the racking use hardware recommended by module racking vendor.
Recommend bolt size of 1/4 and torque no more than 76 in lbs.
If the HY-RSD is mounted at the back of a PV panel, installer shall follow PV module installation instructions.
The minimum distance between any portion of HY-RSD to the back of the PV panel shall be at least 0.5 in.
3. FCC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
BE AWARE THAT INSTALLATION OF THIS EQUIPMENT INCLUDES RISK OF ELECTRIC SHOCK.
NORMALLY GROUNDED CONDUCTORS MAY BE UNGROUNDED AND ENERGIZED WHEN A
GROUND FAULT IS INDICATED.

5. Operating Instructions
HY-RSD are powered by the output of PV panels. Thus rapid shutdown is operable during daytime when the PV
panel is energized. Rapid shutdown can be activated by one of the following two operations only after inverters
have stopped generating power:
1.Disconnect AC power supply.
2.(OPTION) Press the E-STOP button attached to the HY-RSD controller to re-connect the PV panels,
a re-connection command can be sent to each HY-RSD by the following steps:
1.Reconnect AC power supply
2.(OPTION) Release the E-Stop button attached to the HY-RSD controller.
This operation can only be done at day time since the HY-RSD is powered by PV panels.
HY-RSD RAPID SHUTDOWN SYSTEM SHALL BE CHECKED AFTER INSTALLATION.
TEST SHALL BE DONE AT DAYTIME AND WITH ALL INVERTERS HAVE STOPPED GENERATING
POWER. BY MANULLAY PUSHING DOWN THE EMERGENCY BUTTON OR DISCONNECTING AC
POWER SUPPLY OF HY-RSD CONTROLLER, THE DC VOLTAGE ACROSS ANY PV CONDUCTORS
AND BETWEEN ANY PV CONDUCTORS AND GROUND SHALL DROP TO LESS THAN 30 VDC WITHIN
30 SECONDS. INSIDE THE CONTROLLED ZONE, THE DC VOLTAGE ACROSS ANY PV CONDUCTORS
AND BETWEEN ANY PV CONDUCTORS AND GROUND SHALL DROP TO LESS THAN 80 VDC WITHIN
30 SECONDS.
HY-RSD RAPID SHUTDOWN SYSTEM SHALL BE CHECKED REGULARLY TO MAKE SURE IT
FUNCTIONS PROPERLY. TEST SHALL BE DONE AT DAYTIME AND WITH ALL INVERTERS HAVE
STOPPED GENERATING POWER. BY MANULLAY PUSHING DOWN THE EMERGENCY BUTTON
OR DISCONNECTING AC POWER SUPPLY OF HY-RSD CONTROLLER, THE DC VOLTAGE ACROSS
ANY PV CONDUCTORS AND BETWEEN ANY PV CONDUCTORS AND GROUND SHALL DROP TO
LESS THAN 30 VDC WITHIN 30 SECONDS. INSIDE THE CONTROLLED ZONE, THE DC VOLTAGE
ACROSS ANY PV CONDUCTORS AND BETWEEN ANY PV CONDUCTORS AND GROUND SHALL
DROP TO LESS THAN 80 VDC WITHIN 30 SECONDS.
RAPID SHUTDOWN SHALL ONLY BE INITIATED AFTER INVERTERS HAVE STOPPED GENERATING
POWER, THROUGH DISCONNECTING MAIN AC SWITCH OR INVERTER AC SWITCH.
