fuse in the battery circuit is primarily required for protection against short circuit in
Current
the battery cable run. The size of this fuse has to be equal to or larger than the maxi-
mum DC input current of the inverter at Column (2). further, the Amp rating of the
fuse used for protecting a battery cable against short circuit has to be lower than the
Ampacity of the cable so that the fuse blows before the cable insulation is damaged
due to overheating as a result of fault current higher than the Ampacity of the cable.
The Amp ratings of fuses provided with the Inverter Installation Kits are lower than
the wire size provided with the Kit.

The Kits come with 10ft length of cables to cover battery to inverter distance of up to
PST-300S-24E 180A
10 ft. If the actual cable routing distance from the battery to the inverter is less than
10ft, please cut-off the extra length of cables. This will result in reduction in the over-
all resistance of the cable / reduction in voltage drop and consequently, will improve
the efficiency of the inverter system
8.4.6 Dc input connection
The DC input terminals for battery connection (14 & 16 in fig. 6.1c) have nut and bolt con-
nection - bolt size is 5/16" (18 Threads per Inch). Use ring tongue type of terminals on the
wire ends to fit 5/16" bolt size.
8.4.7 Reducing RF interference
Please comply with recommendations given in Section 3 - "Limiting Electromagnetic
Interference".
