In the case of three-phase input, install a three-phase disconnector. In the case of
single-phase input, you are advised to install a disconnector.
When used to power IT system, the UPS (three-phase output) should provide 4-pole
disconnectors, and 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 leakage current protection function, use
the earth leakage circuit breaker recommended.
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 15 kVA/20 kVA model, use AC ground cables that have a cross-sectional area of 25
mm
2
and M6 OT terminals that are 90° bent and have a cross-sectional area of 25 mm
2
.
For 15 kVA/20 kVA model, use battery ground cables that have a cross-sectional area of
16 mm
2
and M6 OT terminals that are 90° bent and have a cross-sectional area of 16 mm
2
.
For 6 kVA model, use ground cables that have a cross-sectional area of 6 mm
2
and M4 OT
terminals and have a cross-sectional area of 6 mm
2
.
For 10 kVA model, use ground cables that have a cross-sectional area of 10 mm
2
and M6
OT terminals and have a cross-sectional area of 10 mm
2
.
