Battery Pack; Repair; Warranty - NEC Ultra2 User Manual

If one of the LEDs is no longer working or is shining much brighter than the other LEDs, the
work light must be repaired.
The internal electronic circuits of the Ultra2 work light are always active, even when the work
E
light is switched off. In case of a defect, the work light must be immediately removed from the
hazardous area. The work light may only be used again in a potentially explosive
atmosphere after an approved repair has been carried out.
The required maintenance interval depends on specific use of the work light and should
therefore be based on the expected application by the user. An interval of 12 months is
recommended as a general guideline for light use.
The housing contains no parts that are important for use, maintenance or inspection, so the
user never needs to open it.

Battery pack

The battery pack of the Ultra2 work light consists of Lithium Polymer cells that are directly
connected to the LED driver. The battery pack contains no parts that require maintenance
and may not be replaced by the user.
To prevent damage caused by the discharge of static electricity, do not remove the battery
pack from the work light and do not touch the electronic circuits.
The battery pack of the Ultra2 work light can be recharged up to 1,000 times. It is normal that
the capacity of the battery pack will decrease as a result of charging and discharging. The
battery pack should be replaced when it is clear that the battery capacity has decreased.

Repair

The Ultra2 work light may only be repaired with original parts, and repairs may only be
carried out by qualified professionals who have been trained on the basis of the EN-60079-
19 standard.
The use of non-original parts can lead to injury to persons and damage to installations. When
non-original parts are used or when repairs have not been implemented properly, the
explosion safety of the Ultra2 work light cannot be guaranteed. In that case, Necplus B.V.
explicitly waives all responsibility.
When repairs are necessary, the work light should be returned to the manufacturer or its
representative.
