Page 18: Step 4 - Ground The System
STEP 4 – Ground the system Each product has an integrated ground protection circuit. The grounding wire is through the trunk cable, and should be securely connected to the ground connector in the junction box. STEP 5 - Ground the system through racking (option) BDM-1000 may also be grounded through the racking. - Page 19 touch live components when voltage sources are still connected or just DO NOT disconnected. connect DC connectors to the product under load. DO NOT Personal protective equipment MUST be worn suitably and properly for all work on the product and the system. Voltage sources MUST be disconnected from the product before all work.
- Page 20 For connection of PV modules to the inverter, all PV modules MUST be fitted with the supplied DC connectors. When assembling the DC connectors, cables MUST be equipped with DC connectors of the correct polarity. e.g. [positive] connection cable to [positive] DC connectors, [negative] connection cable to [negative] DC connectors.
- Page 21 High voltages and energies are present in live components and cables inside the product during operation, e.g. capacitors, connectors. Touching live components and cables may result in death or severe injuries due to electric shock. open the product. DO NOT touch live components.

Page 33: Troubleshooting
TROUBLESHOOTING In case of fault, BDM inverter has multiple protective functions and stops output power. The fault message may be sent to a connected BDG-256 gateway through power line communication. For BDM- WiFi, the same alert is sent through WiFi internet connection, and can be monitored through NEPViewer (please refer to the tech note “Configuring BDM WiFi”). - Page 34 NEVER DISCONNECT THE DC WIRE CONNECTORS UNDER LOAD. ENSURE THAT NO CURRENT IS FLOWING IN THE DC WIRES PRIOR TO DISCONNECTING. AN OPAQUE COVERING MAY BE USED TO COVER THE MODULE PRIOR TO DISCONNECTING. PRODUCT IS POWERED BY DC POWER FROM PV MODULES. MAKE SURE YOU DISCONNECT THE DC CONNECTIONS AND RECONNECT DC POWER TO WATCH FOR THE TWO SECONDS LED ON AND TWO SECONDS LED OFF AFTER DC IS APPLIED.
- Page 35 BDM systems close by, it is highly recommended to install LCF for each micro inverter system to block interference from adjacent other systems. 8. If the problem persists, please call customer support at NEP. DO NOT ATTEMPT TO REPAIR THE micro inverter; IT CONTAINS NO USER-SERVICEABLE PARTS. IF TROUBLESHOOTING METHODS FAIL, PLEASE RETURN THE micro inverter TO YOUR DISTRIBUTOR FOR MAINTENANCE.
