KT-400 Ethernet Four-Door Controller Installation Manual
KT-400 Ethernet Four-Door Controller Maintenance Recommendations
The KT-400 includes a lithium ion rechargable battery (see the KT-400 Ethernet Four-Door Controller PCB View on 
page 8). This 
battery must be replaced by a Kantech technician to avoid any risk of explosion. If the Lithium-Ion battery 
stops working, return the circuit board 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 circuit board and/or the lithium 
ion battery, wrap the KT-400 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 circuit board 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 battery 12 VDC / 7 Ah: It is the end-user and/or installer 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-400 by performing the following tests:
1) Bi-annual test for battery:
Remove AC power from the controller and let it work on battery 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 controller.
2) Annual test for emergency lithium ion battery:
Measure voltage of lithium ion battery when power is totally removed from the controller (AC, DC and backup battery 
power). To ensure maximum operation and to prevent loss of the database, contact your distributor to return the KT-400 
for maintenance if the lithium ion battery voltage measures below 2.5 VDC.
