104.2 Mounting Hardware Mounting hardware is not provided. Care should be taken when selecting mounting hardware to ensure that it is the proper type for the application and sized to safely support the system's full weight when installed, ensuring safe and secure attachment of system to wall surface or building structures. -
Page 7: 105.1 Ac Wiring Preparations
105.1 AC Wiring Preparations 1. Remove the system’s front cover. 2. Make sure the Si- inverter system input and output voltages are correct for the particular appli- cation. Remember that the Si- system provides single-phase power only. 3. The input circuit breaker in the input service panel provides the means for disconnecting AC to the Si- inverter system. - Page 8 Switched Load Operation - Single Circuit - Connected fixure(s) can be externally switched and will illuminate upon loss of utility AC power regardless of external switch position. See Wiring Diagram D. CAUTION: If the Inverter being used has a -CB or -PST option, then please refer to wiring diagrams E, F or G.
