    Always switch off power before you wire, connect, install, or remove any module. The wiring for the SG2 PLR is open and exposed. For the open-board models, all electrical components are exposed. For this reason, it is recommended the SG2 PLR be installed in an enclosure or cabinet to prevent accidental contact or exposure to the electrical circuits and components.

  • Page 5: Examination Before Installation

    • Check to see if the model number of the SG2 matches the model number that you ordered. • Check to see whether any damage occurred to the SG2 during shipment. Do not connect the SG2 PLR to the power supply if there is any sign of damage.
