3.1.3 Preparing Power Cables
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 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 M6
OT terminals that have a cross-sectional area of 10 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
