8.4.5 Recommended Sizes of Battery Cables and Fuses
Sizes of cables and fuses are shown in table 8.2. Sizing is based on safety
considerations in UL-458, NEC-2014 and ISo -10133. Please refer to “Notes for table
8.2” for details.

8.4.6 DC Input Connection
The DC input terminals for battery connection are M8 threaded rods with nuts.
Use the correct cable size (Table 8.2) and cable lugs.
8.4.7 Reducing RF Interference
Please comply with recommendations given in Section 3 - “Limiting Electromagnetic
Interference”.
8.5 AC SIDE CONNECTIONS
WARNING! Preventing Paralleling of the AC Output
1. The AC output of the inverter cannot be synchronized with another AC
source and hence, it is not suitable for paralleling. The AC output of the
inverter should never be connected directly to an electrical Panelboard
/ Load Center which is also fed from the utility power/ generator. Such a
connection will result in parallel operation and AC power from the utility
/ generator will be fed back into the inverter which will instantly damage
the output section of the inverter and may also pose a fire and safety
hazard. If an electrical Panelboard / Load Center is being fed from the
utility power / generator and the inverter is required to feed this panel
