1 About This Guide This guide only applies to the following inverters:CSI-15K-T4001A-E,CSI-17K-T4001A-E, CSI-20K-T4001A-E,CSI-23K- T4001A-E, CSI-25K-T4001A-E. This instruction only provides an overview of the installation of the above-mentioned inverters. Due to product version upgrades or other reasons, this guidance will be updated irregularly. Under no circumstances can this guide replace the user manual and the safety instructions on the product.
3 Installation 3.1 Installation Environment Requirements 1) Do not install the inverter on structures constructed of flammable, thermolabile, or explosive materials. 2) Ensure the inverter is out of children's reach. 3) The ambient temperature should be between -30℃~ 60℃. 4) The humidity of the installation location should be below 100% without condensation. 5) Do not install the inverter outdoors in salt, sulfur, or other corrosive areas.
3.4 Installation Clearance Requirements FIG 3-3 Single inverter installation clearance 3.5 Inverter Installation Step 1: Use the wall-mounting bracket as a template and mark the positions of the drill holes, then drill the 3 holes (Diameter = 11mm, Depth ≥ 55mm). Step 2: Knock expansion anchors into the corresponding three holes, and then secure the bracket by using screws.

4.2 Connecting the PE Cable Since the inverter is a transformerless inverter, neither the negative pole nor the positive pole of the PV string can be grounded. Otherwise, the inverter will not operate normally. Connect the additional grounding terminal to the protective grounding point before AC cable WARNING connection, PV cable connection, and communication cable connection.
4.3 DC Cable Connection Electric shock! The PV array will generate lethal high voltage once exposed to sunlight. Before performing electrical operations, ensure that all cables are uncharged. DANGER Do not turn on the AC circuit breaker before the inverter is electrically connected. Ensure that the DC switch of the inverter is set to OFF.
Step 1: Prepare the Signal Cable. Remove the signal cable’s jacket about 23mm, and then strip the wire insulation layer about 7mm, as per figure below. Core wire cross- Outside Type sectional area diameter Shielded type 0.25-1mm 4~5.5mm 2-core twisted pair (24~18AWG) FIG 4-9 Communication cable requirements Step2: Insert the conductors into the corresponding pins of the plug, and then fix the conductors by screws firmly,as shown...
