When the switch of number 1 is on the 230V side, the output voltage is 230VAC, otherwise is 220VAC. When the switch of number 2 is on the 60Hz side, the output frequency is 60Hz, otherwise is 50Hz. CAUTION: Both the output frequency and voltage change availability after restarting the inverter.
4. Schematic diagram for connections 1)NP260~NP1200 2)NP1500~NP3500 Connect the DC input directly to the battery port is CAUTION: recommended,DO NOT connect to the battery terminal of the controller. Otherwise, the charging frequency spikes of the controller may lead to over-voltage protection of the inverter.
5.Installation instructions 5.1 General installation notes Please read the manual carefully to get familiar with the installation steps before installation. Be very careful when installing the batteries, especially flooded lead-acid battery. Please wear eye protection, and have fresh water available to rinse if any contact with battery acid.
