installation
for normal operation of the inverter, the DC power source must provide >11.0 ± 0.3V and < 15.3 ± 0.3V
and the required current. This DC power source must be a well-regulated DC power supply or alternator
and deep cycle battery system typically found in vehicles and marine crafts. The DC power source may
also be two or more 12 volt batteries connected in parallel. on larger applications, the power source may
be several batteries connected in parallel as shown in fig 4.2.

warnInG!
It is mandatory to install appropriate size of external DC fuse as close to the battery Positive
Post as possible, preferably within 7 inches to protect against fire hazard due to short circuit
along the battery cable run (See fig 4.2). A battery is an unlimited current source that can supply
thousands of Amperes of current under short circuit conditions. If a short circuit occurs in the
cable run at a point between the battery and the inverter, the section of the cable from the
battery to the point of short circuit will be fed with thousands of Amperes of current, the section
of the cable will overheat / melt and is likely to cause fire. It is, therefore, recommended that the
fuse / fuse assembly should have Ampere Interrupting Capacity (AIC) of at least 10,000 A. Class-T
fuse / fuse Holder made by various manufacturers or Marine rated battery fuse (Mrbf) made by
eaton bussmann and distributed by Samlex America / blue Sea Systems may be considered.
Please note that internal DC side fuses have been provided to protect against over current in the
internal DC input circuitry. these internal fuses will not blow due to external short circuit in
the battery cable run.
