EXTREMELY IMPORTANT - READ BEFORE USING CHARGER - SAFETY PRECAUTIONS
• Place the charger on a firm level surface for charging.
•
DO NOT
cover charger.
• Take great care over battery polarity, and observe the battery
manufacturer's recommendations.
• NiCad/Nickel Metal Hydride cells become
WARM
to the
touch when charged. If the pack feels
HOT
to the touch,
disconnect it at once.
• Connect the input leads to the 12v supply first, then connect
the battery to be charged.
•
ALWAYS
disconnect the NiCad/Ni-MH /Pb battery when
NOT
charging, as they may discharge themselves if left connected.
•
DO NOT
allow the input crocodile clips to touch each
other or the case of the charger when the NiCad/Ni-MH/Pb
battery is connected as this may cause a short circuit.
• Avoid short circuits.
• If NiCad/Ni-MH packs are severely overcharged they may
become very
HOT
. For this reason it is always best to place the
pack on an insulated heat resistant surface for charging.
• The charger must
ONLY
be used in completely dry
conditions.
•
DO NOT
disassemble the charger.
•
NEVER
leave the charger unattended whilst charging.
•
DO NOT
fast charge batteries immediately after use while
they are still warm, allow to cool to ambient temperature
before charging.
CONNECTION TO POWER SUPPLY
The SuperNova is designed to operate using either a 12 volt
Lead Acid (Pb) battery or a suitable 10-15volt power supply.
Connect the
red wire
from the charger to the
+ terminal
of
the power source, the
black wire
to the
– terminal
.
When correctly connected, the initial display will appear as
follows, changing after a couple of seconds to, see top right.
