4.4 teleCARE IP Power Supply Wiring
It is important to use the correct wire sizes and to consider the length of the 24Vdc power supply wires.
The minimum acceptable wire size of the 24Vdc bus is 18 AWG (1mm).
For the stub wiring between the 24Vdc bus and the control module wire size 18 AWG (1mm) must be
used.
Warning: Incorrect wire size can result in dangerous overheating of the wires!
Caution: Excessive 24Vdc bus length can result in unacceptable voltage drop! The lowest
acceptable voltage at any point in the 24Vdc distribution is 21.6Vdc.
