• • • • M6x60 expansion bolts are delivered with the solar inverter. If the length and number of the bolts do not meet installation requirements, prepare M6 stainless steel expansion bolts by yourself. The expansion bolts delivered with the solar inverter are mainly used for solid concrete walls. For other types of walls, prepare bolts by yourself and ensure that the wall meets the load bearing requirements of the solar inverter.
3 Connecting Cables 3.1 Preparing Cables • • Connect cables in accordance with the local installation laws and regulations. Before connecting cables, ensure that the DC switch of the solar inverter and all the switches connected to it are set to OFF. Otherwise, the high voltage produced by the solar inverter may cause electric shocks. Prepare cables based on site requirements.
3.3 Installing a WLAN Antenna or Smart Dongle • • If FE communication is used, install a WLAN-FE Smart Dongle (SDongleA-05). You need to purchase the WLAN-FE Smart Dongle by yourself. If 4G communication is used, install a 4G Smart Dongle (SDongleA-03). You need to purchase the 4G Smart Dongle by yourself. Antenna port (ANT) Smart Dongle port (4G/FE) WLAN Antenna (WLAN Communication) Ensure that the WLAN antenna is installed securely.
(Optional) 4G Smart Dongle (4G Communication) • • • • • • • If your Smart Dongle is configured with a SIM card, you do not need to install the SIM card. The configured SIM card can be used only on the Smart Dongle. If your Smart Dongle is not equipped with a SIM card, prepare a standard SIM card (size: 25 mm x 15 mm) with the capacity greater than or equal to 64 KB. Install the SIM card in the arrow direction.
1. Connect the AC output power cable to the AC connector. Three-Core Cable (L, N, and PE) Click The method for connecting a two-core AC output power cable is the same except that the cable is not connected to PE. 2. Connect the AC connector to the AC output port. Check the route of the AC output power cable.
To remove the AC connector, perform the operations in reverse order of installing the AC connector. Then, remove the plug insert, as shown in the following figure. Plug insert 3.5 Installing DC Input Power Cables 1. Ensure that the PV module output is well insulated to ground. 2. Use the Staubli MC4 positive and negative metal terminals and DC connectors supplied with the solar inverter. Using incompatible positive and negative metal terminals and DC connectors may result in serious consequences.
2. Connect DC input power cables. DC input terminals Pull the DC input power cable back to ensure that it is connected securely. Click 3.6 (Optional) Installing Battery Cables • • Use insulated tools when connecting cables. Connect battery cables with correct polarity. If battery cables are reversely connected, the solar inverter may be damaged. Assemble the positive and negative connectors by following the instructions in section 3.5 "Installing DC Input Power Cables.
3.7 (Optional) Installing Signal Cables • • • • When laying out a signal cable, separate it from power cables to avoid strong signal interference. Ensure that the protective layer of the cable is inside the connector, that excess core wires are cut off from the protection layer, that the exposed core wire is totally inserted into the cable hole, and that the cable is connected securely. Block the unused cable hole using a cap and tighten the cable gland.
Crimping Three Signal Cables Connecting Signal Cables Number of Communications Cables Click 4 Verifying the Installation No. Acceptance Criteria 1 The solar inverter is installed correctly and securely. 2 The WLAN antenna is installed correctly and securely. 3 Cables are routed properly as required by the customer. 4 Cable ties are evenly distributed and no burr exists. 5 The PE cable is connected correctly and securely.
5 • • Powering On the System Before turning on the AC switch between the solar inverter and the power grid, check that the AC voltage is within the specified range using a multimeter set to the AC position. If the solar inverter is connected to an LG battery, turn on the DC switch within 1 minute after turning on the AC switch. If you turn on the DC switch after more than 1 minute, the solar inverter will shut down and start again. 1. If a battery is connected, turn on the battery switch. 2.
