To reduce susceptibility to noise, power analog modules
and digital modules from separate power supplies. Do
not exceed a length of 33 ft (10m) for dc power cabling.
Do not daisy chain power or ground from this terminal
base unit to any ac or dc digital module terminal
base units.
Do not exceed a length of 33 ft (10m) for signal cabling.
