9.0 Appendix
9.1 Table 1. Installation Planning Data
Notes:
1. Nominal input current based on rated load.
2. Maximum input current based on rated load + full battery recharge. Full battery recharge
assumed to increase input current with 10%.
3. Nominal power consumption (column 1c) based on nominal input current (1e) and the
corresponding input voltage (1a).
4. Maximum power consumption (1d) based on maximum input current (1f) and the corresponding
input voltage (1a).
5. Suggested input overcurrent protection (1h) based on continous full load maximum input current
(1f). MCCB breaker selection based on continous full load nominal input current (1e) is
acceptable, provided battery recharge time is short.
