6.4 Voltage drop
The max. cable length depends on the voltage drop in the supply voltage cables. The level
of voltage drop is determined by the:
} Cable resistance on the supply voltage cables
} Operating current of the modules
} Load on the modules
To increase the max. cable length, the input voltage can be permanently increased by the
voltage tolerance (see Technical Details).
