7.2.6 Cable Requirements
It is the responsibility of the facilities engineer to comply with all regulatory, legal, and safety
issues concerning appropriate wiring for the facility.
The sample calculations are for reference only. Customers must derive the distance from
supply to device based on cable specifications, expected maximum ambient temperature
and cable temperature rise, estimated connection losses, allowances for error in distance
measurement, and other variables particular to the customer installation.
Sample Calculations for Power Cable
V_supply = 24 VDC, V_device= 20 VDC, I_Receiver_max = 0.50 A, cable resistance per
meter = 9.00 ohms per meter at maximum ambient temperature for 2.5 mm

cable.
Maximum distance from supply to Receiver = (1/2) x (V_supply – V_device) / (I_device_max
x cable resistance per meter)
Maximum distance = (1/2) x (24 – 20) / (0.50 x 9.00 / 1000) = 444 meters
