Separation of Circuits - Power Limited, Non-Power Limited, High Voltage Wiring
The main AC power connection is considered high-voltage and non-power limited. The Battery conductors, and the
low AC and trouble relays are nonpower limited. All remaining circuits are low-voltage, power limited connections.
Proper separation must be maintained between the circuits listed above. All separations in the different wiring must be
maintained by at least 0.25 inches and the wire insulation must be for the higher voltage.
In the panel there are sufficient knock outs located around the periphery of the cabinet to allow the installer to
maintain power limited and non-power limited connections.
Phone Circuits
The FFT-1000 is equipped with 24 Class B or 12 Class A phone circuits and can be expanded upon by adding an
FFT-EXP for an additional 12 Class B or 6 Class A circuits. All circuits are provided with a 5.1K resistor. All phone
circuits are low voltage, supervised, and power limited. FFT phone circuits are rated 24VDC 60mA max.
Wire Impedance = 50 ohms
Relay Outputs
Figure 4. Panel's Dedicated Relay Outputs
The panels have two dedicated common relays, Trouble and Low AC.
The contact rating is 24VDC / 3.0A, 125VAC / 3A, Power Factor: 1.0. These outputs are non-power limited and not
supervised. However, they are power-limited if the power supply to the connected devices is power-limited.
