(1) @ 234 cells and nominal output power;
(2) for tolerance see IEC/EN 60146-1-1or DIN VDE 0558;
(3) valid for 60-500kVA range only in PFC Mode;
(4) including front handle; without handle 830/1030 mm
(5) permitted number of cells = 234-246
(6) only with battery connected
(7) Units rated 250, 300, 400 and 500 kVA can supply loads with PF up to 0.8, leading or lagging, at full nominal output power. For the same ratings, loads with
PF up to 0.9, leading or lagging, can be supplied at full nominal output power with limitation in the maximum value of battery recharge current. Please contact
MASTERGUARD Technical Support for further details. For 800 kVA and 600 kVA for loads with PF> 0.8 or leading please contact MASTERGUARD Technical Support.
(8) Imax input can be deduced from the maximum input power @400V, recharge mode.
Note:
The data shown are typical and not definable in other ways; furthermore the data refer to 25°C ambient temperature and PF= 1 where not specified.
Not all the data shown apply simultaneously and may be changed without prior warning.
If the options described in chapter 13 are added, the data shown in table 12 may vary.
