Models Two different modules compatible with the IEC 61850 protocol are available: Ekip Com IEC 61850 and Ekip
Com IEC 61850 Redundant.
The modules are identical in terms of characteristics and installation methods, except for: display menus,
cabling and addresses for system communication, which are specific for each module.
NOTE: if different indications are not given, the information in the next chapter is valid for
both models
The two modules can be connected at the same time to Ekip Touch so as to expand the potential of the unit
(e.g. for applications where high grid reliability is required).
IMPORTANT: each Ekip Touch can be fitted with only one module per type. The
configuration with two modules of the same model is not allowed (example: two
Ekip Com IEC 61850 Redundant)
circuit-breaker (fixed version) or on the fixed part (withdrawable version).
For references about the connection and terminals, please consult document 1SDM000002A1001; a cable
of the Class 6 S/FTP type (Class 6 with double screening S/FTP) must be used for the communication bus.
To connect the module to Ekip Touch, please consult document 1SDH002009A1505.
NOTE: communication between Ekip Touch and the module is interrupted in the absence of
auxiliary power supply
