• The UPS requires an input neutral connection. Make sure that an
input neutral is connected prior to energizing the UPS. If a 4-pole
automatic transfer switch is installed upstream of the UPS, it must
work with a break before make transition for the phase wires with a
minimum transfer time of 50 ms. Neutral must work with a make
before break transition.
Figure 15 and Figure 16 show the location of the UPS power cable
terminals.
