Separate bypass with different lines:
if the separate bypass option “DI” is present, first remove the jumper between JP and L before to connect the bypass line.
Protective devices must be present on both the main power supply line and the bypass line.
Note:
the neutral of the main power supply line and the bypass line are connected within the UPS, therefore they must be
referenced to the same potential. If the two power supplies are derived from different sources, an isolation transformer must
be installed on one of the inputs.
UPS without any variation in neutral condition and with separate bypass input
connected to independent power supply line
UPS with separate bypass input on independent power supply line
and with galvanic isolation at input
UPS with separate bypass input connected to independent power supply line
and with galvanic isolation at output
