Page 18: Electrical Installation
WARNING! No matter what kind of grounding connection is adopted, it is strictly forbidden to connect the ground of the inverter with the lightning protection of a building, otherwise Autarco will not be responsible for any damage caused by lightning. - Page 19 Installation and operation manual IMPORTANT! B (insulation stripping length) is 2-3mm longer than A (OT cable terminal crimping area) Insert the stripped wire into the OT terminal crimping area, and use an hydraulic clamp-tool to crimp the terminal to the wire (as shown in Figure 5.8). IMPORTANT! After crimping the terminal to the wire, inspect the connection to ensure the terminal is solidly crimped to the wire.

Page 20: Ac Connection
IMPORTANT! In order to improve the corrosion resistance of the grounding terminal, we recommend that the external grounding terminal is coated with silica gel or paint for protection after installation of the grounding cable. 5.2 AC connection DANGER! Never connect or disconnect the connectors under load. NOTICE! The AC connection to the electrical distribution grid must be performed only after receiving authorization from the utility that operates the grid. - Page 21 Installation and operation manual Description Numerical Value Wire Diameter 13-25 mm Traverse cross sectional area 6-13 mm2 (10-6AWG) Exposure Length 13 mm Inside the AC-connector ‘’L1’’, ‘’L2’’, ‘’L3’’, ‘’N’’ and ‘’PE’’ are printed next to the port. The 3 live wires are connected to L1, L2 and L3 terminals respectively.
- Page 22 are e.g.: nominal AC current, type of cable, type of routing, cable bundling, ambient temperature and maximum specified line losses. The steps to assemble AC grid terminal connector are listed as follows: Step 1 — Strip the outer jacket 70mm and strip off each cable isolation for about 13 mm. Put the cable through the nut and sleeve of the socket element, insert corresponding terminals and tighten with Allen wrench.

Page 23: Meter Installation
Installation and operation manual NOTICE! It is important that the AC wires are connected to the right terminals as indicated by the “L1”, ‘’L2’’, ‘’L3’’, “N” and “Ground” symbols on each AC connector. Damage to the inverter by wrong connections are not covered under warranty !. In some countries a second protective conductor is required. - Page 24 The Autarco LH series inverter uses RS485 cable to communicate with the Meter and the CAN-bus to communicate with the battery's Battery Management System (BMS). The image below shows the assembly of the RS485/CAN communication cables. LH-series Inverters...
- Page 25 Installation and operation manual NOTE: The CAN cable enables the communication between the inverter and the Li-ion battery, please check for latest model compatibility before installation. Procedure for connecting the CAN-cable. 1. Take out the CAN cable (terminal marks ‘CAN' on one end and 'to Meter' on the other end). 2.
- Page 26 NOTE: To use this function, please contact Autarco if this function is supported in your country. To protect the inverter's AC grid connection conductors, Autarco recommends installing breakers that will protect against overcurrent. The following table defines OPCD ratings for each model;...
