
In the case of single-phase input, you are advised to install a disconnector.

When used to power IT system, the UPS (single-phase output) should provide 2-pole
disconnectors.

The UPS is a large leakage current device. Do not configure a circuit breaker that has the
leakage current protection function. If you need the leakage current protection function,
use the earth leakage circuit breaker recommended. If multiple UPSs share an earth
leakage circuit breaker (ELCB), increase the leakage current accordingly.

The leakage current of the 6 kVA UPS is less than or equal to 100 mA. The leakage current
of the 10 kVA UPS is less than or equal to 200 mA.

When selecting the earth leakage circuit breaker (ELCB), consider the leakage current of
the UPS and downstream loads.

The battery cable cannot be longer than 10 m.

You can install linked circuit breakers for both the N wire and L wire. No independent
circuit breaker is allowed for only the N wire.

For the 6 kVA model, use ground cables that have a cross-sectional area of 6 mm
2
and M4
OT terminals that have a cross-sectional area of 6 mm
2
.

For the 10 kVA model, use ground cables that have a cross-sectional area of 10 mm
2
and
M6 OT terminals that have a cross-sectional area of 10 mm
2
.
Table 3-2 lists the recommended power cable specifications for the UPS standard version.
