Care should be taken when selecting mounting hardware to as- sure that it is the proper type for the application and sized to safely support the systems full weight when installed assuring safe and secure attachment of system to wall surface or building structures. For ease of installation, the factory recommends that the head size of mounting screws or bolts be small enough to pass through the keyhole knockouts provided for mounting. -
Page 7: 105.1 Ac Wiring Preparations
105.1 AC Wiring Preparations 1. Remove the system’s front cover. 2. Make sure the LPS inverter system input and output voltages are correct for the particular appli- cation. Remember that the LPS system provides single-phase power only. 3. The input circuit breaker in the input service panel provides the means for disconnecting AC to the LPS inverter system. - Page 8 Switched Load Operation - Single Circuit - Connected fixure(s) can be extremely 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 -4C or -4AO option, then please refer to wiring diagrams E, F or G.
