Positioning of passive Terminals

Hint for positioning of passive terminals in the bus terminal block
EtherCAT Terminals (ELxxxx / ESxxxx), which do not take an active part in data transfer within the
bus terminal block are so called passive terminals. The passive terminals have no current consump-
tion out of the E-Bus.
To ensure an optimal data transfer, you must not directly string together more than 2 passive termi-
nals!

Installation positions

Constraints regarding installation position and operating temperature range
Please refer to the technical data for a terminal to ascertain whether any restrictions regarding the installa-
tion position and/or the operating temperature range have been specified. When installing high power dissi-
pation terminals ensure that an adequate spacing is maintained between other components above and be-
low the terminal in order to guarantee adequate ventilation!
