noteS:
1. cable Size
• As per NEC, size is based on Ampacity ≥ 1.25 times the rated DC Input Current
• Conductor / Insulation rating : 105 °C
2. fuse Size
• Type: Class-T or Marine Rated Battery Fuse (MRBF)
• The rating of the fuse should not exceed the Ampacity of the Cable
3. Distance between inverter and Battery and % Voltage Drop
• Voltage drop is calculated based on length of cable = 2 x Distance to consider total length of Positive
and Negative cables
• % drop is calculated with respect to rated battery voltage of 12.5V
!
caution!
• Please ensure that the recommended external fuse specified in Table 4.1 above (Fuse is
not supplied) is installed in series with the positive cable and is as close to the Battery (+)
terminal as possible (preferably within 7”).
• Please ensure that all the connections are tight. Loose connections may cause overheated
wires and melted insulation.
ac Side connections
feeding utility ac power - use as Backup ac power Source
- Power cord with NeMA5-15 Plug (10A, b in fig 3.1) is used to feed AC input power to the
unit when the unit is used as a backup AC Power Source.
- Use 15A/20A, GfCI protected AC outlet for this connection.
