Transfer to by-pass mode is to be inhibited, and an alarm initiated if voltage, frequency and/or phase shift of by- pass power is outside acceptable tolerances. Re-Transfer To Inverter: Re-transfer of critical load from auto by-pass source to inverter (UPS mode) is only to be possible under the following conditions: 6. 7. 8.
