• Ampere rating of the recommended fuse is equal to the Ampacity of the wire. for
safety against overheating of the wire beyond its rated conductor temperature and
consequent possibility of fire due to damage to wire insulation, the Ampere rating
of the fuse should not exceed the Ampacity of the wire. If, however, exact value of
standard size of fuse equal to the Ampacity of the wire is not available, the next
higher standard size of fuse may be used
• Samlex Inverter Installation Kits are recommended for various installation require-
ments covering battery to inverter distances of up to 10 ft. Depending upon the dis-
tance between the battery and the inverter, voltage drops will vary as shown in Table
8.1. note: For broader suitability, 10 ft. wires are provided with each kit to cover
distance of up to 10 ft. to prevent unnecessary voltage drop, cut off excess length of
wire that is more than the distance between the battery and inverter. For example, if
the distance is 3 ft., use only 3 ft. and cut off the balance 7 ft.

Dc input connection
The DC input terminals for battery connection (8 & 9 in fig. 6.1) have nut and bolt connec-
tion - 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.
Reducing RF interference
Please comply with recommendations given in Section 3 on page 11 - "Limiting Electro-
magnetic Interference".
