8.5.9 Connecting the auxiliary power supply to the mains
Both the QC-APS-15 and QC-APS3-15 external auxiliary power supplies
and the auxiliary power supply integrated in the QC-PS-025 must be
supplied with line voltages between 400 (1-10 %) V AC and 480 (1+10 %)
V AC and, in this way, internally generate the +24 V DC to power the
control circuits of the system equipment.
Connect the three phases of the mains (after the mains filter) to the L1’,
L2’, L3’ terminals of the
A20 input connector of the auxiliary power supply
using conductors with a cross-section of 1 mm². Also connect the FE
terminal (functional earth or service earth) to the PE protective earth.
For more information on the A20 connector, refer to
A20 CONNECTOR.
