Introduction
The Magnum Energy ANL Fuse/Fuse Block is designed to provide code com-
pliant overcurrent protection for DC systems up to 32-volts. It protects the
battery bank, inverter, and cables from damage caused by short circuits and
overloads. The ANL fuse cartridge delivers instantaneous protection in the
event of a short circuit, as well as a time delay to allow the momentary current
surges that are common in inverter applications. Magnum small fuse blocks
are available in 125 and 200 amp models. Our ANL fuse holder is molded
from glass-fi lled nylon, has an insulating cover, and includes two black rub-
ber terminal insulators to protect conductive areas from accidental shorts.
The ANL fuses are rated for 32-volt DC systems (48-volts maximum) and
are an economical alternative to the Class-T fuses. These fuses have a clear
window that provides open-fuse indication; and, have a durable Polyethersul-
fone body and riveted construction to offer superior service life in heavy-duty
applications.
Fuse selection is based upon the size of the conductor between the battery
and the load. Keep in mind that the conductor’s current carrying capability
is affected by: the length of the cable between the battery and the load, and
the conductor’s wire type and temperature rating. Refer to the Table 1 for
assistance in selecting a fuse.
Installation
The battery, fuse block, and inverter should be located as close together as
possible – without being in the same enclosure. Batteries can produce explosive
gasses that may be ignited by the fuse. For code compliance, locate the fuse
within 18” (45 cm) of the battery, and with at least 6” (15 cm) clearance from
other equipment on each end. When changing the fuse, it may be energized
by the battery; allow additional clearance if grounded metal surfaces (such
as the inverter’s chassis) are nearby.
Attach the fuse block base to a secure surface using the appropriate hardware
(refer to Figure 1). Make the connections to the fuse block fi rst (see Figure 2
for proper hardware stacking), then to the battery, and fi nally to the inverter.
Place the rubber terminal insulators on the battery cables before securing the
cable lugs to the fuse posts.
NOTE: The fuse should not be installed in the grounded conductor.
Torque the Hex nuts to ~150 inch-pounds (16.9 N-m). The lock washers
provided must be installed to ensure a quality and long lasting connection.
Check the cables for correct polarity with a voltmeter before making the fi nal
connections to the inverter.
WARNING: Failure to comply with torque specifi cations may
result in damage and premature failure of the product. Failures
caused by not adhering to the proper torque specifi cations are
not covered by warranty.
WARNING: Before replacing a fuse, ensure all AC/DC power
sources are de-energized (i.e., breakers opened, fuses removed)
to prevent accidental shock.
