Instructions for installation

4.1 Safety Instructions

DANGER

• To prevent risk of electric shock during installation and maintenance, please make sure that TSOL-RSDM-CQ or any other control unit, such as the DC switch of inverter, are turned off.

NOTICE

• All electrical installations must be done in accordance with the National Wiring Rules of Standard and local code.

4.2 Pre-installation Check
Although TSUN’s products have surpassed stringent testing and are checked before they leave the factory, it is uncertain that the products may suffer damages during transportation. Please check the package for any obvious signs of damage, and if such evidence is present, do not open the package and contact your dealer as soon as possible.

4.3 Installation of TSOL-RSDM-DS and TSOL-RSDM-DD
WARNING

• While TSOL-RSDM-DS or TSOL-RSDM-DD are used without TSOL-RSDM-CQ, be sure that this photovoltaic rapid shutdown equipment (PVRSE) does not perform all of the functions of a complete photovoltaic rapid shutdown system (PVRSS). This PVRSE must be installed with other equipment to form a complete PVRSS that meets the requirements of NEC (NFPA 70) section 690.12 for controlled conductors outside the array. Other equipment installed in or on this PV system may adversely affect the operation of the PVRSS. It is the responsibility of the installer to ensure that the completed PV system meets the rapid shut down functional requirements. This equipment must be installed according to the manufacturer’s installation instructions.

1. Fix the rapid shutdown device (TSOL-RSDM-DD&TSOL-RSDM-DS) on the frame of solar module.
2. Connect the input of rapid shutdown device to the solar module.
3. Connect the outputs of all the rapid shutdown devices one after another.
4. While TSOL-RSDM-DS or TSOL-RSDM-DD are used without TSOL-RSDM-CQ, connect each string of the rapid shutdown devices to the solar inverter.

4.4 Installation of TSOL-RSDM-CQ
WARNING

• While TSOL-RSDM-DS or TSOL-RSDM-DD are used with TSOL-RSDM-CQ, be sure that this photovoltaic rapid shutdown system (PVRSS) incorporates one or more pieces of equipment that exercise the rapid shutdown control of PV system conductors required by section 690.12 of the NEC (NFPA 70). other equipment installed in or on this PV system may adversely affect the operation of this PVRSS. it is the responsibility of the installer to ensure that the completed PV system meets the applicable rapid shut down functional requirements. this equipment must be installed according to the manufacturer’s installation instructions.
