Installation
The internal power supply of a central unit can only generate limited
electrical power via the system bus. The power requirements of
all installed slaves can be determined as a busload as follows:
The maximum system bus length is derived from the voltage drop
across the cables used.
The total of all the busloads must not exceed 32 without an additional
power supply. The maximum total cable lengths, depending on the
total planned busloads, are shown below:
