Operation
When normal utility-supplied power is present, the LSN model central lighting inverter provides load-side line conditioning with “brownout” protection, and charges the system batteries when required. When utility-supplied power is interrupted, or the voltage varies from predetermined limits, the system will automatically and instantaneously transfer to emergency mode without interruption to connected loads. DC battery-derived emergency power is inverted to AC power and supplied in a pure sine wave output form for 90 minutes (standard run time). A low voltage battery disconnect circuit prevents “deep discharge” damage to the batteries during prolonged power outages. When normal power is restored
the system will automatically restart, providing power to connected loads and recharging the batteries. The charging circuit will bring the batteries to full recharge within UL time standards.

Construction
The LSN cabinet is constructed of steel, finished with a light g ray paint and features locking cabinetry and password-protected user interface for security. Louvers at front and top of cabinet allow venting.

Installation
Input power entry point is from the cabinet top. Bottom channels for lifting straps and wall brackets for anchoring. Servicing is accessible from cabinet front
