THINGS YOU SHOULD KNOW

Circuit Breaker Protection

The Freedom Inverter/Charger is supplemental circuit breaker protected. The INVERT/CHARGE breaker on the front of the unit protects against sustained inverter/ charger over-current conditions.

This supplemental circuit breaker protects the output of the unit when operating in “Invert Mode” and protects the internal battery charger circuits when operating in “Charge Mode.” When an over-current condition occurs, the circuit breaker is reset by pushing the button back in after the fault is removed. This circuit breaker is not suitable for branch circuit pro- tection. To comply with NEC, additional branch circuit rated breakers may be required between the output of the unit and the load.

Freedom 25 and 30 have two outputs. Both outputs are protected by the supplemental circuit breaker when operating in “Invert Mode.” During transfer/charge operation, the outputs are protected by the circuit breakers feeding the two inputs to the unit.

Thermostat Controlled Cooling Freedom Inverter/Chargers are equipped

with a thermostatically controlled fan that cools the unit so it can operate continually at its rated output.

Inverter Idle Circuit

The idle circuit reduces battery power consumption when no AC load is present. Response from idle is instantaneous. When using a Freedom or Link remote control panel the idle threshold is adjustable. The unit does not produce 120 volts when in idle. An idle pulse is sent out approximately twice a second to see if a load is present. To bring the unit out of the idle condition, apply a load larger than the idle set point.

Low and High Battery Shutdown When in inverter mode, if the battery

voltage drops to 10.0 volts, the inverter will automatically shut off. Charge the batteries to 13.5 volts to automatically resume operation.

Voltage shutdown also occurs for a high battery condition at 15.5 volts. Operation will resume automatically when the battery voltage drops below 15.5 volts. Check all DC sources on the system for the reason for the excessive voltage.

Power Sharing

When connected to an external AC source the battery charger and transfer functions are engaged. A unique Power Sharing feature automatically reduces the AC power consumption of the battery charger when the loads threaten to trip the incoming circuit breaker.

Freedom 25 and 30 have two AC inputs. The battery charger is supplied AC from AC input #1. These models will reduce the current available to the charger when the demand for current to the load on AC output #1 reaches the factory default setting. AC input #2 is a direct transfer to AC output #2 and has no power sharing control.
