— Accessories for Ekip trip units
Ekip Signalling Modbus TCP (Fig. 32) Modbus is an external signalling unit designed for DIN rail installation. The function of the signalling module is to share, via an Ethernet network with Modbus TCP communication protocol, information about the state of circuit-breakers that might not have the ability to provide such information via Eth- ernet, and also to allow these circuit-breakers to be operated via remote control.

Ekip RTC and Ekip AUP Signalling contacts (Fig. 33) The signalling contacts allow the Ekip trip units to acquire the ready-to-close status of the circuit- breaker, as well as its racked-in, test or racked-out position. These contacts can be optionally installed in the accessories area of SACE Emax 2 equipped with Ekip Dip, Ekip Touch and Ekip Hi-Touch trip units. Ekip Link and Ekip Com modules are always supplied with Ekip RTC and Ekip AUP.

Measurement and protection Measurement Enabler module (Fig. 34)
The Measurement Enabler module is supplied standard with Ekip Touch trip unit and is installed to the right of the trip unit. This module enables the trip unit to internally measure phase and neutral volt- ages, as well as power and energy. In particular, the Measurement Enabler module makes the platform always customizable through the activation of dedicated software packages available in the ABB Ability MarketplaceTM. Depending on the functionality desired, a software package may need to be pur - chased separately. The voltage outlets are installed standard on the lower terminals and can be moved to the upper terminals upon request. No external connection is required, except for rated voltages higher than 690V. In this case, the voltage connection is moved outside the circuit-breaker by using voltage transformers connected to the terminal box. The installation of external outlets does not guar- antee Class 1 accuracy.
