Inverter Module Installation and Operation

Overload Protection

The inverter will deliver the rated load power continuously at the rated ambient temperature. It will also reliably operate up to 1600 Watts without further restriction on the maximum ambient temperature. The internal temperatures of critical components monitored by the DSP will determine operating time at this overload range. Beyond 1600 Watts, the DSP computes the power and extrapolates the operating time at that power level before shutting down. The maximum overload rating is

3000 Watts for 5 seconds. After each overload trip event, the inverter re-starts after a 10-second pause. Should three such events occur within a 2-minute interval, the inverter shuts down permanently. Normal operation can be restored by clearing the alarm (see “To Clear an Alarm” on page 3–11) or using the front panel switch.
