BATTERY CHARGER CONTROLS

NOTE: A buzz, or hum is normal when the output cables have been disconnected and the AC power cord is still connected to an electrical source (i.e. wall outlet).

OPERATION – Model SE-70MA

Two switches permit operation and volt selection.

Switch #1 – OPERATION SELECTOR

Mode 1 – Manual setting: Warning: This charging must be moni- tored and stopped when the battery is charged. Overcharging will damage the battery.

Mode 2 – Automatic setting for Conventional and Low Mainte- nance Batteries. If you are not sure of your battery type, use the Conventional setting.

Mode 3 – Automatic setting is for Maintenance Free and Deep Cycle batteries.

Switch #2 – VOLT SELECTOR

Select either the 12 or 24-volt setting: Use the 12-volt setting for a 12-volt battery and the 24-volt setting for two 12-volt batteries hooked up in series.

If more than one battery is to be charged, be sure the total battery voltage is not less than that of the charger or damaged could result to batteries and charger. Diagram for series hook up is shown below:

Use #10 AWG jumper wires to connect batteries.

DC CONNECTION PRECAUTIONS

1.Connect and disconnect DC output clamps only after setting any charger switches to off position and removing AC cord from electric outlet. Never allow clamps to touch each other.

2.Attach clamps to battery posts and twist or rock back and forth several times to make a good connections This tends to keep clamps from slipping off terminals and helps to reduce risk of sparking.

F.FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE

A SPARK NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. FOLLOW THESE STEPS TO REDUCE RISK OF SPARK NEAR BATTERY:

1.Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part.

2.Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.

3.Check polarity of battery posts. POSITIVE (POS, P,+) battery post usually has larger diameter than NEGATIVE (NEG, N, - ) post.

4.Determine which post of battery is grounded (connected to the chassis). If negative post is grounded to chassis (as in most vehicles), see No. 5. If positive post is grounded to the chassis, see No. 6.

5.For a negative-grounded vehicle, connect POSITIVE (RED) clamp from battery charger to POSITIVE (POS, P,+) ungrounded post of battery. Connect NEGATIVE (BLACK) clamp to vehicle chassis or engine block away from battery. Do not connect clamp to carburetor, fuel lines, or sheet- metal body parts. Connect to a heavy gage metal part of the frame or engine block. (Figure 2)

6.For a positive-grounded vehicle, connect NEGATIVE (BLACK) clamp from battery charger to NEGATIVE (NEG, N, -)

ungrounded post of battery. Connect POSITIVE (RED) clip to vehicle chassis or engine block away from battery. Do not connect clamp to carburetor, fuel lines, or sheet-mebl body parts. Connect to a heavy gage metal part of the frame or engine block. (Figure 3)

7.When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery terminal, in that order.

8.See charge period for length of charge information.
