Installation Environment
The location for installing and using the battery charger is important to ensure that the charger operates normally and
to avoid situations where there may be damage to the charger or the battery it is connected to.
The EG4 Battery Charger has built in intelligent temperature protection which operates in two aspects. The first is
stopping the charge function when the battery or unit is too hot. It is best to place the charger in the same location so
it can use it’s ambient temperature sensor to ensure it is not charging while the temperature is not appropriate for the
battery. The second is to achieve the best charging current according to the environmental temperature by adjusting
the charging voltage. For these reasons, it is highly recommended that the installation of the charger is close to the
battery it is charging.
It is also important that the heatsink fins of the charger are not blocked, to allow any heat produced by the charger to
escape. Please place the charger in a location where there is adequate airflow to prevent overheating, dust
accumulation, and in a location where there is no chance of flammable substances coming into contact with the
charger.
Lastly, although the charger is designed to be water resistant, it should not be installed in a location that would
frequently be exposed to water. The water resistant design is to ensure safe operations in the event that water is
splashed onto or around the charger. It is not designed to be consistently submerged or exposed to water during
operations.
Installation Instructions
Once you have a suitable location for the EG4 Battery Charger to be installed, please adhere to the following
information to ensure proper operation of the charger.
