Installing the Device Installation Requirements Space Angle Mounting Hole Dimensions Installing the Solar Inverter 1. Install the mounting bracket. Avoid drilling holes in the water pipes and cables buried in the wall.
• 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.
Connecting Cables 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.
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.
(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.
Installing the AC Output Power Cable Ensure that the protective layer of the AC output power cable is inside the connector, that the core wires are totally inserted into the cable hole, and that the cable is connected securely. Failing to do so may cause device malfunction or damage. 1.
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 Installing DC Input Power Cables 1. Ensure that the PV module output is well insulated to ground. 2.
