Slew rate (max. change rate of
synchronisation frequency)
Hz/s Setting range: 0.2, 0.5, 1 (UPS module), 0.2 (parallel system)
1. Factory set to 380V. 400V or 415V can be selected by service engineer at site.
2. Factory set to 50Hz. 60Hz can be selected by service engineer at site. Note that the system frequency may only be changed
when the UPS is in bypass mode. It is strictly prohibited to change the system frequency when the UPS supplying the load via
the inverter.
3. EN 50091-3 (1.4.58) crest factor 3:1, non-linear load.
4. IEC/EN 62040-3/EN 50091-3 also for 0 - 100% - 0 load transient. Transient recovery time: returns to within 5% of steady state
output voltage within half a cycle.
