6. Fuses according to DIN LV HRC type gL, 500V assumed. MCCB load capacity must be 8xIn
(nominal current) for minimum 10ms.
7. Suggested load side overcurrent protection (3b) based on nominal output current (3a).
8. Nominal battery voltage assumed to be 2V/cell (Lead technologi).
9. Recommended cable sizes, see "External Connection" section of this guide.
CAUTION! Cable sizes must comply with national and/or local legal regulations.
10. Nominal battery discharge current (2c) based on full rated load and nominal battery
voltage (2V/cell).
11. Maximum battery discharge current (2d) based on full rated load and battery voltage at end of
discharge (1.7V/cell).
12. Full load discharge power from battery based on nominal battery discharge current
(2c) x nominal battery voltage (2x192cells x 2V/cell), or maximum battery discharge current
(2d) x battery voltage at end of discharge (2x192cells x 1.7 V/cell).
13. Heat dissipation based on nominal full load capacity and linear load.
