Voltage Selector Switch (model SI-70MA only)

Use this switch to set the charger to charge a 12 volt or 24 volt battery. NOTE: These chargers are not recommended for 8 or 16 volt systems.

LED Indicators

•Full Charge – When lit, this LED indicates that the battery is fully charged and the charger has stopped charging and switched to the Maintain Mode of operation (Automatic charge only).

•Power On – When lit, this LED indicates that there is AC power supplied to the battery charger.

11.OPERATING INSTRUCTIONS

This battery charger must be properly assembled in accordance with the assembly instructions before it is used.

The charger does not have an ON/OFF switch. The On and Off commands are controlled by plugging the charger into an AC electrical wall outlet only after the battery connections have been made. See the warning label on the charger for the correct input voltage.

This charger can be used with the following batteries:

Charging

1.Ensure that all of the charger components are in place and in good working condition, for example, the plastic boots on the battery clips.

2.Connect the battery following the precautions listed in sections 6 and 7.

3.Select the appropriate settings for your battery.

4.Connect the AC power following the precautions listed in section 8. Make sure to place the charger on a dry, nonflammable surface like metal or concrete.

5.To disconnect, reverse the procedure.

Manual Charging (models SI-82-6MA and SI-70MA)

When a Manual Charge is performed, the charger will continue to charge and will not shut off. You must keep a visual check on the ammeter to determine when the battery is charged. Be sure to monitor the charging process and stop it when the battery is charged. Not doing so may cause damage to your battery or result in other property damage or personal injury.

Automatic Charging Mode

When an Automatic Charge is performed, the charger switches to the Maintain Mode (see below) automatically after the battery is charged. For a battery with a starting voltage under 1 volt, use the Manual Mode first to pre-charge the battery for five minutes, to get additional voltage into the battery for the charger to analyze.
