Accessories for Ekip trip units

Ekip Signalling Modbus TCP (Fig. 32)
It is an external signalling unit designed for DIN rail installation. 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 Ethernet, 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 cir-
cuit-breaker, as well as its racked-in, test or racked-out position. These contacts can be optionally in-
stalled 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 with Ekip Touch trip units by default 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
Marketplace . Depending on the functionality desired, a software package may need to be purchased
TM
separately. The voltage outlets are installed on the lower terminals by default 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 guarantee
Class 1 accuracy.
