3.
Provide as much ventilation as possible for the charger and battery.
4.
Do not set a battery on top of the charger.
DC connection precautions
Connect and disconnect DC output clips only after setting any charger switches to off
position and removing the AC cord from the electric outlet. Never allow the clips to
touch each other.
Making DC Connections
Attach the clips to your battery posts and twist or rock them back and forth several
times to make a good connection. This tends to keep the clips from slipping off the
terminals and helps to reduce the risk of sparking.
4. OPERATING THE CHARGER
Proper Operation
After making the wiring connections according to these instructions, examine the LED
lights on the charger.
When the red LED is on, this means that the 12 volt battery is deeply discharged, and
is being recharged by the 2603. If the charger is connected to an unusually large or a
deeply discharged battery, the 2603 may require considerable time to bring the
batteries to full charge.
When the green LED turns on, your battery is already at or near full charge, and the
charger is now maintaining the battery. If the green LED gradually fades on and off,
this is an indication of an unusually efficient battery. This battery is receiving a very
small maintenance charge from the 2603. If the green LED flashes after the battery
has been recharged, this means that your battery requires a lower maintenance
charge than normal. Leave the 2603 connected and it will function normally. Now you
can store your batteries at full charge indefinitely without overcharging, when batteries
are properly maintained.
Overload Protection
If the 2603 encounters a DC overload (excessive demand) it will reduce it’s output
voltage to a safe level to prevent damage. If its positive and negative connectors are
touched together creating a short, it will instantly reduce its output voltage to nearly
zero, and both the red and green LED lights will turn off. When the overload is
removed, the 2603 automatically resumes normal operation.
