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