Page 12: Installation Of The System
04 Installation of the System 4.1 Installation Environment Requirement • Mount the System on a wall with sufficient load-bearing capacities such as a brick wall or concrete wall. If it is mounted on a wooden wall, evaluate its weight capability and the possibility of fall first. Meanwhile, the System must be grounding. -
Page 13: Installation Of The System
4.3 Installation of the System 1.Hold the battery handle to take it out from the packing box, and remove the protective case. 2.Hold the handle to separate the battery and the installation backboard. Keep the removed screws properly for future use. - Page 14 3.Perforate the mounting position with an impact drill (10mm diameter, 80mm depth) and clear the debris from the hole after drilling. Mounting hole distribution as follows. Mounting holes can follow either rectangular distribution(blue border) or dia-mond distribution(green border). 4.Install wall hanging plate •...

Page 19: Electrical Connection
14.Install the control box. 15.Repeat step1~step6 to fi nish the fi fth, sixth, seventh, and eighth batteries from bottom to top. • There is a risk of injury when the battery is raised or lowered, or when it is fi xed to or removed from the wall stands since each battery weighs 37 KG (81.6 lbs). Raise the platform to ensure safety before installing the last 5-8 bat-tery modules. • The upper part of the battery module can only be wall-mounted, so the base plate is used for position only. Remove the base plate after positioning to re-duce stress on the control box. 4.4 Electrical Connection 4.4.1 Remove covers of the control box and batteries modules... -
Page 20: Install Pe Cables
4.4.2 Install PE cables • The internal ground cables are delivered with the battery system and con-nected in series. The two neighboring batteries are connected by ground points. • The external ground cables are not supplied. Cables with a sectional area big-ger than 10AWG are recommended. • Connect battery module PEC cables by M6 screws and an M6 OT terminal. Rec-ommended tightening torque is 5N.m. • Connect control box module ground cables by M5 screws and an M5 OT termi-nal. Recommended tightening torque is 3.5N.m. -
Page 21: Connect Power Cables
4.4.3 Connect power cables • Connect battery power cables in series, which means connect the anode of the battery to the cathode of the next battery. Connect power lines of the control box and batteries in parallel, which means connect the negative line of the bat-tery on the upside of the control box to its cathode while the positive line on the lower side to its anode. • Customers have to prepare cables used to connect the main control box and inverter. 6AWG copper core is recommended. • Confi rm that the switch of the control box is off . 1.Route the cable through the nylon tube, seal ring and waterproof joint, then crimp on OT ter- minals. • Ensure that the seal ring of the waterproof joint is properly 2.Connection fi gure placed in the plastic ring. -
Page 22: Connect Communication Cables
4.4.4 Connect Communication cables 1.Route the cable through the nylon tube, seal ring and waterproof joint, then crimp on the RJ45 terminal. 2.Connection fi gure • Remove the maintenance cover with a cross screwdriver before the connection. • Unscrew and remove the compression fi tting fi rst and screw it after routing the nylon tube. • Ensure that the seal ring of the waterproof joint is properly placed in the plastic ring. • Do not short-circuit the positive and negative terminals of the battery module when installing because there is no disconnecting switch in a single battery module. • Recommended torsion for tightening the compression fi tting is 7N.m. • Connect communication cables of all batteries and the communication box in sequence, except the control box and the fi rst battery under it. Then connect the bottom and the top battery module. 3.Seal the unused communication ports under the main control box by terminal resistances after connecting communication cables. -
