DESCRIPTION:
NE287 is a charger for gel and lead storage batteries. The batteries should have a nominal voltage of 12V and a capacity of no less
than 100Ah. The NE287 also works as a power supply.
OPERATION:
POWER SUPPLY MODE:
NE287 foperates as a power supply unit when there is a 230V mains supply and there is no service battery installed or connected. In
this mode output voltage is fixed at 13,5V with maximum current of 17A (230W max) o 21A (280W max).
In this mode, the LED green flashes.
BATTERY CHARGER MODE::
If there is a service battery and is powered by the mains supply, NE287 operates as a battery charger.
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 next page).
The battery charger uses a combination of Constant Current and Constant Voltage. This makes it possible to significantly reduce charging
time and prevents permanent damage to the batteries, even if the charger is permanently connected to the mains 230V.
When battery charging is activated the power supply immediately provides the necessary voltage, so that the battery does not discharge (this
is true if the charging voltage is lower than the maximum voltage available from the power supply, otherwise the battery will discharge in any
case with voltage equal to the difference I
The battery charger can be connected to a temperature probe (to be placed on the battery), to adapt the charging algorithm selected at the
temperature of the battery.

( ) The charge is momentarily interrupted and e the alarm will be reset itself when the battery cools. Verify the ventilation of the battery
compartment or the battery status.
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
- The power supply unit/battery charger must be connected by
qualified personnel only.
- Connection to the mains power supply must be carried out to national
installation regulations.
- 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. Do
not obstruct the air vents on the lid.
- Never place the charger directly above or below the battery being
charged; gases or fluids from the battery will corrode and damage
the charger.
- Do not use the power supply unit/battery charger in places where
there is an explosion hazard.
- When recharging, lead acid batteries produce explosive gas
internally: avoid causing flames or sparks and place the batteries in
a well-aired place
- Never charge a frozen 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.
- Study all battery manufacturer's specific precautions such as
removing cell caps while charging and recommended rates of
charge.
- Do not connect the device to mains voltage different from nominal
value (230Va.c. ±15%)
- Before connecting the power supply unit/battery charger to a
transformer, make sure the voltage produced is stable..

- Do not carry out maintenance without disconnecting from the 230V
mains.
- Disconnect the power supply before connecting or disconnecting the
battery connection.
- Charger surface may be hot while plugged in and for a period of time
thereafter.
- If the cables or output connectors are damaged contact the service
center.
- Do not alter the device or the cabling of battery charger.
- Do not attempt to open the charger. There is risk of electric shock
even if the charger is unplugged. No user serviceable components
inside.
- 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.
- 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.
- The warranty is cancelled if the device is used inappropriately and the
manufacturer declines all responsibility for damage to people or
things.
