— Algorithm The algorithm consists of 4 steps 1. Measure: measures the total power flow through the SACE Emax 2 which implements the function Algorithm Measure 2. Synchronization: defines the time intervals in which the average power demand is measured 3. Evaluation: evaluates whether the demand is too high, whether it is within the normal limits or whether it is significantly lower Synchronization 4. Load management: decides which are the loads to be disconnected/reconnected, in compliance with: – Priority – Respect times Evaluation – Reordering Load Management September 16, 2021 Slide 22

— Description of operation Connection details Each load is controlled in one of the following ways 1 - Wired control – 1 digital input (mandatory) to get information about the open/closed state of the downstream device – 1 digital input (optional) to get information about the enabled/disabled state of the downstream device (or tripped state or redundant contact state) – 2 digital outputs to give the opening/closing command to the downstream device when it is a circuit breaker or switch disconnector 2 - Ekip Link control – Using Ethernet cable with Ekip Link module Ekip Power Controller is able to automatically manage the following situations, allowing integration with the selectivity of the protection devices in the plant: – Tripping of protection trip units – Manual operation September 16, 2021 Slide 23
