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
