1. Introduction 1.1 Purpose This document provides detailed instructions and valuable safety information regarding the installation, electrical connection, and maintenance of following Chint Solar Crystalline Photovoltaic modules: CHSM6610M CHSM6610M (BL) CHSM6610M/HV CHSM60M-HC CHSM60M(BL)-HC CHSM6610P CHSM6610P/HV CHSM60P-HC CHSM6612M CHSM6612M/HV CHSM72M-HC CHSM6612P CHSM6612P/HV CHSM72P-HC All the instructions should be read and understood before installation.
touch and drag on the ground. c) After unpacking the modules should be installed that day as far as possible. It’s recommended to take the right amount of modules according to the progress of the project every day. Heavy rain and other inclement weather may have the potential to soak the packaging which can affect product reliability, such as storms, typhoons, hurricanes or other events in which they may be blown away.
cover all items, please refer to the specific construction standards. 2. Safety 2.1 General Safety 2.1.1 Consult and follow local codes and other applicable laws concerning required permitting as well as installation & inspection requirements, rules, and regulations. 2.1.2 2.1.3 2.1.4 2.1.5 PV modules should be installed and maintained by qualified personnel. Use the same performance modules within a given series. Follow all safety precautions of all components used in the system.
2.2.6 Do not touch the terminal box and the end of output cables (connectors) with bare hands. 2.2.7 Do not unplug the connector under load. 2.2.8 Do not work alone. 2.2.9 Wear a safety harness if working far above the ground. 2.2.10 Do not wear metallic jewelry, which can cause electric shock, while installing or troubleshooting the PV system. 2.2.11 Follow the safety regulations for any and all other system components, including wires, connectors, charging regulators, batteries, inverters, etc. 2.2.
and facing south in the northern hemisphere. 3.1.5 To maintain the modules’ Class C fire rating, the fire class of the roof and building materials should be higher than Class C. 3.1.6 To maintain the modules’ fire performance type 1(for US market), it could be possible to achieve the Class A system fire rating, with a Class A class racking system. 3.2 Installation Methods 3.2.
Fig c 3.2.2 Clamping on the frame surface 3.2.2.1 Single glass module Modules can be laid either across the supporting bars (Figure d & f) or parallel to the edge of frame (Figure e & g) . Fig d Fig f Fig e Fig g Remark: 1) The length of supporting bars must be longer than the length of module frame, otherwise Chint Solar (Zhejiang) Co.,Ltd. | Add:1335 Bin´an Road, Binjiang District, Hangzhou | P.C: 310053 Tel: 0086-571-5603 1888 | Fax: 086-571-5603 2316 | Website: http://energy.chint.
please confirm with our product team to get approval. 2) As for above figure d, the solid red rectangles indicate primary clamp installation positions and the center positions of long frames where clamps can be added for additional support. 3) Illustrations (figure d、e、f、g) of the four different methods for clamping modules on the frame with aluminum clamps. “ ” means the aluminum clamp’s permissible clamping range. The recommended installation position shows as below table.
recommended 17~23Nm when the property class of bolts and screws is Class 8.8.
4.1.2 4.1.3 4.1.4 4.1.5 4.1.6 4.1.7 4.1.8 4.1.9 Pmpp under the standard test conditions (irradiance of 1000 W/m2, AM1.5 spectrum, cell temperature of 25℃. The IEC & UL standard maximum system voltage for the regular module series is 1000V, the 1500V standard products are also available according to the requirements. The IEC & UL standard maximum system voltage for half-cell module series is 1500V (except for black modules).
4.2 Grounding 4.2.1 4.2.2 4.2.3 4.2.4 4.2.5 4.2.6 (n) Grounding the aluminum frame with copper wire The grounding requirements must be checked in accordance with the applicable regulations and standards before work is started. Use the marked 5.5 mm grounding holes to ground the anodized frame. Use one M5 nut, two M5 cut washers, one M5 plain washer, one M5 spring washer, and one M5 bolt and the copper wire. All nuts, bolts, and washers are type M5 and should be made of stainless steel (Fig. (n) ).
5.2 If snow is present, a soft-bristled brush with soft bristles may be used to clean the surface of the modules. 5.3 Regular electrical and mechanical inspection by a licensed professional will keep the system safe and operating at maximum efficiency. 5.
