Fix the uninterrupted power supply in its place.
2 - electRIcal InstallatIon
Connect the mains 230VAC (fig. 2).
The mains supply for this device must include a neutral phase circuit
breaker of maximum 16A C curve, rapidly accessible upstream from the
supply.
All cables must be attached to the frame of the cabinet before being
connected to the various terminals strips, to prevent any pulling on these
terminal strips. In addition, the wires of each terminal strips must be
attached to each other to maintain the various isolations if an initial fault
occurs.
Connect the 24VDC output (fig. 3).
Connect if needed the 2 dry contacts indicating mains failure and low
battery.
The triggering of the
low battery contact can
be adjusted with the
potentiometer 5 (fig. 3).
Connect the battery before closing the Sigma UPS and switching it on
(fig. 4).
When the installation (24V) includes several Sigma UPS the earth poles of
the sigma UPS should be interconnected.
