KT-NCC Maintenance Recommendations
Important: Only a technician should perform the following maintenance
recommendations.
The KT-NCC includes a lithium-ion rechargeable battery, see KT-NCC Printed Circuit Board on page 39.
This battery must be replaced by a
Technician ONLY
to avoid any risk of explosion. If the lithium-ion
battery stops working, return the PCB to Kantech. Do not crush, puncture, open, disassemble or
otherwise mechanically interfere with the battery. Do not try to recharge the battery. If you need to
dispose of the PCB and/or the lithium-ion battery, wrap the KT-NCC in non-conductive tape. Check with
your local authorities for battery disposal regulations.
Warning:
Do not store the batteries in such a way that they come into contact with each other or with
any piece of metal. Explosion or fire may occur. Should fire occur, use only dry chemical fire
extinguishers. Do not use water to put out the fire. Do not heat the batteries. Do not dispose of
the batteries or PCB in a fire. Do not disassemble the batteries. Do not apply pressure to or
deform the batteries. Ensure that the above precautions are strictly observed by related
departments, including, but not limited to, production, sales and outside contractors.
Regarding the recommended backup battery 12 VDC / 7 Ah: It is the technician’s responsibility to assure
that the disposal of used batteries is made according to the waste recovery and recycling regulations
applicable to the intended market. Use the recommended battery type ONLY.
It is highly recommended to test the KT-NCC by performing the following tests:
1.
Biannual test for battery:
Remove AC power from the KT-NCC and let it work on battery backup power for one hour. This test will
ensure that in the event of a power failure, the battery will be able to support normal operations. This test
should be performed twice a year. Once the test has been performed successfully, reconnect AC power
to the KT-NCC.
2.
Annual test for emergency lithium-ion battery:
Measure voltage of lithium-ion battery when power is totally removed from the KT-NCC (AC, DC and
backup battery power). To ensure maximum operation and to prevent loss of the database, contact your
distributor to return the KT-NCC for maintenance if the lithium-ion battery voltage measures below
2.5 VDC.
