2.3 Preparing to Charge
Before charging a battery with the battery charger, read the following precautions:
1. Do
NOT
operate the battery charger if the input or output cables or an LED is damaged or defective.
2. Make sure all accessories connected to the batteries you are charging are OFF.
3. If the battery or batteries must be removed from the equipment, always remove the ground terminal from the battery
first.
4. Be sure the area around the battery is well ventilated while the battery is being charged. Gas can be effectively blown
away using a piece of card board or other non-metallic material as a hand fan.
5. Clean the battery terminals. Be careful to keep corrosion from coming in contact with your eyes.
6. For all batteries, carefully follow the manufacturer’s recharging instructions.
7.
Never
allow the ring terminals to touch each other.
8.
Never
charge a frozen battery.
3 Installation
Instructions
3.1 Location
1. The case of this charger will become warm during operation. Because the charger is convection cooled
(airflow over the back of the charger), the optimum mounting position for the charger is vertical. Mounting on
its back on a horizontal surface may cause the charger to slightly reduce amperage output due to the thermal
protection built in. Do not install the charger on carpeted, upholstered, or varnished surfaces.
2. Locate the charger as far away from battery as DC cables permit.
3. Never place the charger directly above the battery being charged; gases from the battery will corrode and
damage the charger.
4. Never allow battery acid to drip on the charger when reading electrolyte specific gravity or filling battery.
5. Do not operate the charger in a closed-in area or restrict ventilation in any way.
6. Do not set a battery on top of the charger.
3.2 Mounting
1. Refer to the installation drawings for recommended mounting locations.
2. Use the hardware provided with the kit, or use corrosion-resistant 3/16 in. dia. or #10 bolts, backed by a flat washer
and secured to the mounting surface with a split-ring lock washer.
3. Hold the charger to the mounting surface and mark the holes.
4. Remove the charger and drill the mounting holes.
5. Align the charger and assemble the mounting hardware. Secure the charger.
3.3 DC
Connection
Connect one battery to one battery charger as shown in the connection diagrams. For 24 volt systems with two
batteries, two battery chargers are required.
Observe the following precautions when connecting and disconnecting the battery charger :
1. Connect and disconnect DC output clips only after removing AC cord from electric outlet. Never allow the ring
terminals to touch each other.
2. Check polarity of the battery posts. The POSITIVE (POS., P, +) battery post usually has a larger diameter than the
NEGATIVE (NEG., N, –) post.
3. Connect the red charger output lead to the POSITIVE post. Connect the black charger lead to NEGATIVE. See
the connection diagrams for more details.
4. Do not face the battery when making the final connection.
5.
When disconnecting the charger, disconnect the AC cord and then remove the clips from the battery
terminals.
