  • Page 24: Preparing For The Installation

    Installation Preparing for the Installation Important: cautionary markings located in this guide and in your inverter manual. Code Compliance Governing installation codes vary depending on the location and type of installation. Electrical installations must meet local and national wiring codes. Installations of this equipment should only be performed by skilled personnel such as qualified electricians and Certified Renewable Energy (RE) System Installers.

  • Page 25: Configuration Planning

    Configuration Planning Wiring scenarios will depend upon the configuration of the overall system (i.e., Off Grid or On Grid, and output requirements). Pre-installation and mounting instructions apply to all configurations. Follow the instructions from page 2–4 to page 2–19 for all installations. After the pre-installation procedures have been completed, select the wiring scenario that applies to your configuration.

  • Page 26: Pre-Installation

    Use flexible conduit. • When mounting the components such as the ACCB-L or DCCB-L next to the inverter, bias the mounting screws away from the inverter. This will allow "sliding" room within the mounting holes, so that the ends can slide apart without being removed from their mounted position.

  • Page 27: Ventilation Requirements

    Ventilation Requirements Minimum clearance for ventilation around the Long AC Conduit Box must be at least 12 inches (305 mm) at the top, the ends, and in front. This clearance is needed to prevent recirculating hot air from the inverter’s exhaust (DC side) from going back into the inverter’s intake (AC side).

  • Page 28: Removing And Replacing The Cover

    Installation Removing and Replacing the Cover Remove the top cover to install additional breakers and to connect the AC wiring of the Long AC Conduit Box to the Sine Wave Plus Inverter. Follow the diagram below to locate and remove, or replace, the appropriate screws and washers on the cover of the Long AC Conduit Box.

  • Page 29: Installing Or Removing The Blockoff Plates

    Be sure to disconnect all DC and AC power before removing the inverter and installing the blockoff plates. Align the holes on the Blockoff Plate behind the holes provided from the inside of the ACCB-L chassis.

  • Page 54: The Ac Bypass Switch

    Operation The AC Bypass Switch During normal operation (Figure 3-2 on page 3–3), AC power passes from the single external AC source (generator or grid) through the inverter to the AC loads. The inverter monitors the incoming power and uses this power to keep the batteries charged.

  • Page 55: Normal Operation

    Normal Operation External AC power passes to the AC Bypass Switch through the inverter to power the load (Figure 3-2). In this configuration, power passes from the inverter, through the AC Bypass Switch, to the connected load. When external AC power is not available, power from the external DC source is used by the inverter to power the AC loads.

  • Page 56: Ac Input/Output Off

    Operation AC Input/Output Off No power to the load or inverter (Figure 3-4). In this configuration, power from both the external sources of AC and the inverter is removed from the loads. This allows the inverter that is connected to the AC Bypass breaker to be removed for service.
