1 Introduction This manual introduces the installation and configuration of below models of SAJ Solar Inverters. Sununo-TL1 .5K\Sununo-TL2K\Sununo-TL3KB\Sununo-TL4KB Sununo-TL3KA\Sununo-TL4KA\ Sununo-TL5K Only qualified electricians who have read and fully understood all safety regulation contained in this manual can install the inverter. Installers must be aware of native regulations, laws and safety requirements.
2 Assembly Parts After you receive the SAJ Solar Inverter, please check if there is any damage on the carton. Please also check the inside completeness and for any visible external damage on the inverter or any accessories. Contact your dealer if anything is damaged or missing. B A C D E F G I G H Figure 2.

3 Installation 3.1 Installation Mode Noted: Ensure the label visible on the SAJ Solar Inverter after installation. Please see more details installation information in the User Manual. Avoid prolonged rain. Avoid direct sunlight. Avoid direct sunlight. Ensure sufficient airflow.
Install on the wall correctly. Figure 3.1 3.2 Safety Clearance Please follow up the safety clearance below when install one or multiple SAJ Solar Inverter. Please contact SAJ for more installation information. Minimum Clearance（cm） Direction Above 30 Below 50 Side 50 Front 5 Figure 3.2 3.3 Mounting Procedure. 1) Use the rear panel in the package as a drilling template and mark the positions of the drill holes, as illustrated below.
Sununo-TL1.5K/2K Sununo-TL3KB/4KB Sununo-TL3KA/4KA Sununo-TL5K Figure 3.3 2) Drill 6 holes in the wall (in conformity with position marked in above picture), and then place expansion tubes in the holes using a rubber hammer. Figure 3.4 3) Mount the rear panel. Wring six screws into the expansion tubes and tightly mount the rear panel on the wall.
Figure 3.5 4) Carefully attach the inverter to the rear panel according to the position of the screws. Make sure the backside of the inverter is closely against the rear panel. When two people transport the inverter, make sure each one use the hand grip in right position as illustrated in the picture. Figure 3.6 5) Pay attention to the four notches cut in both flanks of heat sink (as illustrated in above picture), which should be placed in corresponding hooks from the rear panel.
3.4 Special Installation (only for France) Connect the ground wire to the earthing, terminal, and then tighten them as following figure. Figure 3.

DANGER Danger to life due to potential fire or electricity shock. Never connect or disconnect the connectors under load.
Assembly Instructions: 1) Strip the cable with the length 0.276 inches (9/32″) - (7mm) and please be careful NOT to nick conductors. Figure 4.2 2) Screw off and separate each component of AC connector as follows. Figure 4.3 3) Pass the cable through each component from right to the left as follows. Tighten the screws with 3N·m torque. Figure 4.4 4) Use a screw driver and loose the three screws at the side of the straight plug.
Figure 4.5 Connect L, N and protective conductor to the AC label. terminal in accordance with the To do this, the insulated earthling conductor must be 5mm longer than the insulated L and N conductors! L and N must not be swapped. The ground wire shall be larger than phase conductor. Figure 4.6 5) Aim the terminals on the straight plug to the holes of the grommet, and then compress them together. Figure 4.
6) Finally, connect the straight plug to the AC terminal on inverter. Pay attention to the polarity of the terminals to avoid wrong connecting. 4.3 DC side Connection NOTE The cable length on DC side should not exceed 30 m. DANGER DANGER to life due to potential fire or electricity shock. Never connect or disconnect the connectors under load.
Male side connector (M) Female side connector (F) Figure 4.8 Assembly Instructions: 1) Strip the cable with the length 0.276 inches (9/32")-(7mm) and please be careful NOT to nick conductors. Figure 4.9 2) Use specified strip tool in this step. Adjust the strip stopper and put the cable in corresponding notch to strip the length of 7mm. See below figures. Figure 4.10 Figure 4.
Pin contact Socket contact Figure 4.12 Figure 4.13 4) Crimp contact barrel by using the hex crimping die, ensure it is fixed.See below figures. Crimped pin contact Crimped socket contact Figure 4.14 Cable requirements: Cable Size Cable pull – out force requirement 2.5 mm2 Min. 310 N (70 Lbs) 4mm2 Min. 400 N (90 Lbs) 6 mm2 Min. 450 N (100 Lbs) 10 mm2 Min. 500 N (110 Lbs) 1) Crimp contact barrel by using the hex crimping die. Ensure it is fixed. See below figures. Figure 4.
Figure 4.16 2) Wrest the cap by using the torque of 2.6~2.9N·m. Figure 4.17 3) After wrested the cap tightly, align the 2 half connectors and mate them together by hand until a “click” is heard or felt. Figure 4.18 5 Pre-running Inspection 5.1 DC Side Inspection DC input voltage should be within the voltage range as specified in the datasheet (please refer to the Max. DC Voltage and Min. DC Voltage in the datasheet).
Check the insulation status between solar panels and ground. Make sure the DC side ground insulation is larger than 1000kΩ; otherwise it is forbidden to connect to public grid. Make sure DC input cable is tightly connected with DC input terminal. 5.2 AC Side Inspection Ground cable should be in appropriate cross section size. An over-long or over-slender ground cable can lead to inverter errors. SAJ should not bear responsibility to any defect or safety accident caused by an absence of ground cable.
