BATTERY CHARGER NE286
GB
DESCRIPTION:
NE286 is a charger for gel, AGM and lead acid batteries. The batteries must have a nominal voltage of 24V and capacity
within the limits given in the technical characteristics.
OPERATION:
The battery charger uses a combination of charge at constant current and constant voltage. This makes possible a
significant reduction of the charging time and prevents permanent damage to the battery.
Use the dip switches to choose the charging algorithm according to the type of battery. At switch on, the green led flashes to
indicate which algorithm is selected via dip switches (see table page 7).

IMPORTANT SAFETY INSTRUCTIONS. SAVE THESE INSTRUCTIONS.
- Failure to install and operate the charger in accordance with these instructions may result in damage to the charger or injury to the
operator
- Working in the vicinity of a lead-acid battery is dangerous, batteries generate explosive gases during normal battery operation. For
this reason it is of the utmost importance that each time before using the charger, you read and follow the instructions provided
exactly.
- To reduce the risk of battery explosion, follow these instructions and those marked on the battery.
- To reduce the risk of injury, charge only lead-acid, AGM or gel batteries (be sure that the selected charging curve is suitable for the
type of batteries that have to be charged). Do not attempt to charge any other type of chargeable or non-chargeable battery; these
batteries may burst, causing personal injury and damage.
- Lead-acid batteries produce internal explosive gases during charging: prevent flames and sparks and provide adequate ventilation.
- Never charge a frozen battery.
- Study all battery manufacturer's specific precautions such as removing cell caps while charging and recommended rates of charge.
- Never place the charger directly above or below the battery being charged; gases or fluids from the battery will corrode and damage
the charger. Locate the charger as far away from the battery as DC cable permit.
- Do not attempt to open the charger. There is risk of electric shock even if the charger is unplugged. No user serviceable
components inside.
- Charger surface may be hot while plugged in and for a period of time thereafter.
- Do not expose the charger to the rain. For indoor use only.
- A minimum of 30mm clearance should be provided at each end of the charger. Install the battery charger in a dry and well aired
place
- If the cables or output connectors are damaged contact the service center.
- Disconnect the power supply before connecting or disconnecting the battery connection.
- This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance
in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance
shall not be made by children without supervision.
- For the charging of automobile batteries:
- The battery terminal non connected to the chassis has to be connected first. The other connection is to be made to the chassis,
remote from the battery and fuel line. The battery charger is then to be connected to the supply mains.
- After charging, disconnect the battery charger from supply mains. Then remove the chassis connection and then the battery
connection.
