SAFETY INSTRUCTION
WARNING:
- 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 CODE S. WHEN THE PHOTOVOLTAIC ARRAY IS EXPOSED TO LIGHT, IT SUPPLIES A DC VOLTAGE TO
- THE PVG RSD. THIS PHOVOLTAIC RAPIC SHUTDOWN EQUIPMENT(PVRSE) DOES NOT PERFORM ALL OF THE FUNCTIONS OF A COMPLETE PHOTOVOLTAIC RAPIC
- 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 RAPIC SHUTDOWN
- FUNCTIONAL REQUIREMENTS. THIS EQUIPMENT MUST BE INSTALLED ACCORDING TO THE MANUFACTURER’S INSTALLATION INSTRUCTIONS .
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:
- 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
- Consult the dealer or an experienced radio/TV technician for help.
- Changes or modifications not expresslya pproved by the party responsible for compliance may void the user’s authority to operate the equipment.
INSTALLATION
WARNING: PVG IS A DEVICE WITH MEMORY. IF THE LAST STATE OF A PVG IS UNKNOWN,
PLEASE TEST AND CONFIRM IT IS AT OFF STATE BEFORE WIRING.
ON-STATE PVGS MAY RESULT IN HIGH VOLTAGE ON THE PV STRINGS. BE AWARE THAT
INSTALLATION OF THIS EQUIPMENT INCLUDES RISK OF ELECTRIC SHOC K.
Attach PVGs to the Racking
Mount PVGs on the racking use hardware recommended by module racking vendor.
Recommend bolt size of 1/4″ and torque no more than 76 in lb.s
If the PVG is mounted at the back of a PV panel, installer shall follow PV module installation instructions. The minimum distance between any portion of PVG to the back of the PV panel shall be at least 0.5 in.

Port PV-1 must be connected to a PV panel to power the PVG. Cables (PV+ and PV-) of an unused PV port shall be connected .
OPERATING INSTRUCTIONS
WARNING: PVG RAPID SHUTDOWN SYSTEM SHALL BE CHECKED AFTER INSTALLATION.. TEST
SHALL BE DONE AT DAYTIME AND WITH ALL INVERTERS HAVE STOPPED GENERATING POWER.
BY MANULLAY PUSHIN G DOWN THE EMERGENCY BUTTON OR DISCONNECTING AC POWER
SUPPLY. OF PVG CONTROLLER, THE DC VOLTAGE ACROSS ANY PV CONDUCTORS AND BETWEEN
ANY PV CONDUCTORS AND GROUND SHALL DRO PTO 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 .
WARNING: PVG 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 SUPPL.Y OF PVG 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 .
WARNING: RAPID SHUTDOWN SHALL ONLY BE INITIATED AFTER INVERTERS HAVE STOPPED
GENERATING POWER, THROUGH DISCONNECTING MAIN AC SWITCH OR INVERTER AC SWITCH.
PVGS 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:
- Option-1 Disconnect AC power supply
- Option-2 (OPTION) Press the E-STOP button attached to the PVG controller
- To re-connect the PV panels, a re-connection command can be sent to each PVG by the following steps:
- Option-1: Reconnect AC power supply
- Option-2: (OPTION) Release the E-Stop button attached to the PVG controller
- This operation can only be done at day time since the PVG is powered by PV panels.
PV PANEL MONITORING USING BDG 256
(OPTIONAL)
Using BDG-256 gateway, DC current, voltage, power, daily energy, and
temperature of each PV panel can be monitored using MICROVIEWER locally, or
NEPVIEWER remotely. BDG-256 usage should refer to the BDG-256 gateway manual.
