2.8 Installation depending on the system earthing arrangement (SEA)

UPS with common Normal and Bypass inputs (Figure 9)

Change in SEA between upstream and downstream or galvanic isolation required (Figure 10)

UPS with separate Normal and Bypass inputs (Figure 11)

Change in SEA between upstream and downstream or galvanic isolation required (Figure 12)

The transformer is not necessary if:

Normal and Bypass inputs are connected to the same source, l

and wires cross sections and wires lengths on Input and Bypass inputs are identical, l

and upstream protection is provided by only one switch with RCD (residual current l

device) for Input and Bypass inputs.
