6.4 Installation Steps Step 1: The steps for installing the bracket is as follows: a. Place the bracket against the wall, adjust the hole position with a level (K1) , and mark the positions of the 8 holes. b. Remove the bracket, drill the holes with a hammer drill (φ8mm, depth range 45-50mm), and tighten the expansion bolts to ensure that the bracket is securely installed. - Page 11 Step 3: Insert 2 pcs of M5*10 screws (F2) into the holes on the left and right sides of the mounting bracket then tighten the screws. Stand-alone mode： Step 1: Insert the 2 parallel plugs (H2) into the LINK IN and LINK OUT ports respectively. Step 2: Connect the inverter cables:...
- Page 12 Note: Power cable (K2) must be pulled straight from the battery DC+/- for more than 80mm before bending. Make sure that the power cable connected to the inverter is connected vertically and that the vertical length is greater than 30 cm. If the cable is bent close to the terminals, it may cause poor line contact and result in burnt terminals.
- Page 13 Parallel mode： Step 1: Connect the parallel cables: The steps for parallel connection of batteries is as follows: a. Insert the parallel plug (H2) into the LINK IN port, this battery is defined as the Main battery (whichever battery can be set as the Main). b.
