If mounted vertically (on a wall), the inverter can be mounted either portrait style or landscape style. Ensure that there is enough space inside the enclosure for the wiring and ventilation.

  • Page 19: Safety Considerations For Mounting

    INSTALLATION 2.3.1 Safety Considerations for Mounting WARNING: EXPLOSION/FIRE HAZARD Do not install in a confi ned area where battery gases can accumulate. Battery gases can create an explosion or fi re hazard if ignited by a spark. Ensure the enclosure is ventilated well enough to disperse any accumulated gases. Do not install over an easily combustible surface, since the heat sink may get hot under certain operating conditions.

  • Page 20: Mounting Procedure

    INSTALLATION 2.3.2 Mounting Procedure To secure the inverter to the mounting surface: 1. Place the SureSine on the surface where it will be mounted and determine where the wires will enter/exit. • Be sure there is suffi cient bending room for the wires and other auxiliary connections, as required by local code.

  • Page 21: Adjusting Settings

    INSTALLATION Adjusting Settings The SureSine has eight (8) DIP Switches that allow for adjusting specifi c operational parameters for the inverter. Each switch has an ON/OFF position. See Section 2.4.2 on page 12 for details on specifi c settings. IMPORTANT: Check that the DIP Switches are properly confi gured for the designed installation prior to installing the inverter.
