2. 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.

IT IS IMPORTANT TO NOTE THAT NOTHING INSIDE THE PRODUCT SHOULD BE MODIFIED, ASIDE FROM THE CABLE

CONNECTORS. ANY MODIFICATION TO THE INTERNAL COMPONENTS OF THE PRODUCT MAY RESULT IN MALFUNCTION

OR DAMAGE, AND MAY ALSO VOID THE PRODUCT'S WARRANTY.

ALL INSTALLATION SHOULD FOLLOW THE LOCAL ELECTRIC CODES.

WARNING:

WHEN THE PHOTOVOLTAIC ARRAY IS EXPOSED TO LIGHT, IT SUPPLIES A DC VOLTAGE TO THE PVG RSD

WARNING:

THIS PHOTOVOLTAIC 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 ADVERSELY 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. THIS EQUIPMENT

MUST BE INSTALLED ACCORDING TO THE MANUFACTURER’S INSTALLATION INSTRUCTIONS.

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:

●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.

4. INSTALLATION

Please be aware that the installation of this equipment carries the risk of electric shock. Conductors that are typically

grounded may become ungrounded and energized when a ground fault is detected.

4.1 NEP Parts Needed

In addition to the micro inverters, PV modules, racking, and associated hardware, you’ll need the BDM-600x installation

kit. This kit includes the following items:

●AC trunk cable (one per micro)

●Protective end cap (one per branch circuit)

●Tail cable (one per branch circuit- 16’ long)

●Male connector (optional) Used to make extension cables

●BDG-256 (or BDG-256P3 for 3 phase)

The BDM-600 Ships six (6) to a box with each box measuring approximately 18” x 13.5” x 16”and weighing

57 lbs. A typical pallet contains 27 boxes.

4.2 Additional Parts and Tools Required

In addition to the PV modules, racking, and associated hardware, you’ll need the following parts:

●MLPE rail or frame attach clamps (2 per microinverter)

●AC junction boxes (multiple options possible)

●Cordgrip with locknut or strain relief fitting (one per branch circuit)

●A subpanel may be required for systems with multiple branch circuits

●Cable clips

●Sockets, wrenches, torque wrench, multimeter, small ﬂat head screwdriver, and mirror with extension rod

●Lightning and surge suppressor (recommended)

4.3 Lightning Surge Suppression

●It's important to note that lightning strikes can cause damage to PV systems even without directly hitting the

equipment or building where the system is installed. The electrical grid can experience voltage spikes induced

by a nearby lightning strike, which can in turn damage the equipment. While the BDM-600x includes integrated

surge protection that is greater than that found in most string inverters, it is still possible for the protection to

be exceeded if the surge has sufficient energy, resulting in damage to the equipment.

●Because the NEP Limited Warranty does not cover "acts of God" such as lightning strikes, and given that these

strikes can occur anywhere, it is recommended to install surge protection as part of any solar installation. Any

surge protection devices should be installed in accordance with the vendor's instructions

4.4 Installation Procedure

WARNING: : DO NOT CONNECT BDM-600x TO THE UTILITY GRID OR ENERGIZE THE AC CIRCUIT(S) UNTIL YOU HAVE COMPLETED ALL

OF THE INSTALLATION PROCEDURES AS DESCRIBED IN THE FOLLOWING SECTIONS.

Installing the BDM-600x Micro inverter System involves several key steps:

●Measuring service and installing the AC branch circuit junction box.

WARNING: ONLY USE ELECTRICAL SYSTEM COMPONENTS APPROVED FOR WET LOCATIONS

●Attaching the BDM-600x Micro inverter to the racking.

●Connecting the BDM-600x Micro inverter daisy chain connections

●.Grounding the system (optional)1

●Completing the BDM-600x Micro inverter installation map and connecting the PV modules.

The finished system should be similar as in the diagram. Detailed installation steps are listed in the following

section.

1DC circuits of BDM-600x are isolated and insulated from ground. An integrated grounding protection circuit is included in the micro inverter.

4. 5 Install the AC Branch Circuit Junction Box

●Measure service entrance conductors to confirm AC service at the site. Acceptable ranges are

shown in the table below:

1. BDM-600x-240A & BDM-600x-208A (North America)

2. BDM-600x-AU (Australia and New Zealand)

3. BDM-600x-EU (Europe)

●Mount the adapter plate onto the PV racking system at a suitable location, usually at the end of a row of

modules.

●Install a junction box with the adapter plate that is compatible with the microinverter.

●Connect the open wire end of the AC interconnect cable to the junction box using a gland or strain relief fitting

that is appropriate for the cable. It is important to use a strain relief connector with a diameter opening of 3/8

inches for the AC interconnect cable.
