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.
THINGS YOU SHOULD KNOW
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.
