Cable: install as stationary
and protected equipment !
Maximum cable length 70m
for a 10-wire standard cable
with a maximum of 200 nF/
km and 1mH/km.
The length of the installed
cable is defined as 20 m
because of the RS-232
specifications.
System appraisal
(see EC-Type Examination Certificate KEMA 02ATEX1108 X):
Co <= 125nF; Lo <= 100µH; Lo/Ro <= 33µH/W
