8.4 Sercos III connectors
The device features two connectors Sercos III, installed on the upper side of the device, used for the commu-
nication with other devices equipped with SIII field-bus interface. As specified in the standard protocol Sercos
III, there is no functional difference in using connector F1 or F2, therefore it is possible to connect the field-bus
cables in any order. The pin configuration of the connectors is standard for Ethernet wiring; therefore, it is pos-
sible to use common Ethernet cables (min. FTP Cat. 5E) to connect the MST S4 module to Sercos III bus.
Use an adequately sized wire, according to the current flowing. A lower cross-section might
cause fire, due to overheating caused by the wire.
In order to meet the requirements of the EMC 2014/30/UE, the cable must not be longer
than 30 meters.
The MST S4 module is a high-tech electronic device, sensitive to electrostatic discharges
(ESD). Take maximum care to prevent such discharges, by adhering to the prescriptions of
the law, in order to avoid damages to the device.
