(3) Relocating the batteries and battery equalizer
• Be sure to relocate the batteries and the battery
equalizer as a set.
(4) Precautions concerning the battery equalizer
• Do not disconnect the cables from the 12 V and
24 V terminals of the battery equalizer unless it
is absolutely necessary. If the cables must be
disconnected from the terminals for some
reason, note the following precautions.
• After disconnecting the battery cables, wait for
10 minutes, and then disconnect the battery
equalizer cables.
• When reinstalling the battery equalizer, ensure
that the terminal side is uppermost, and also
that the height of the terminals of the battery
equalizer is the same as the height of the
battery terminals.
• When connecting the cables to the battery
equalizer terminals, apply silicone sealant as
described below to ensure that the terminals
are fully waterproofed with sealant. If the
sealing is inadequate, the terminals will
corrode, which may lead to an electric fire,
fusing of terminals, or other serious accident
and damage.
• How to apply silicone sealant
Place the battery equalizer in a horizontal
position with the terminals facing upwards.
Connect the 12 V, 24 V, and negative
battery cables to the battery equalizer after
disconnecting the cables from the 12 V,
24 V and negative terminals of the battery.
