ENGINE GENERATOR INTEGRATED SWITCHGEAR The Engine Generator Integrated Switchgear (EGIS) is designed for low voltage applications from 208V through 480V. The basis of design for EGIS is a modular approach to a paralleling system, beginning with a Master Breaker Panel for the first two generator sets, and adding pre-engineered structures to accommodate a utility incomer, up to 8 additional generator sets (total of 10) and up to 24 monitored, sheddable loads. The modular EGIS system utilizes EMCP3.S paralleling controllers to perform synchronization, power factor control, load sharing, and system monitoring. The user is able to monitor and control the system through an industrial touchscreen HMI. Simple configuration screens allow for ® easy setup, installation and startup by your local Cat dealer. MASTER BREAKER PANEL (MBP) The Master Breaker Panel houses the electrically operated circuit breakers for the first two Cat engine generator sets. Load take-off lugs or cross-bus are available power flow options. This main structure also includes the generator controls for the first two generators, the system HMI interface and the redundant system level controls. I/O points within the control panel provide for plug-in expansion of controls as additional generators and utility structures are added. • 12 Inch Graphical Color Touch Screen (HMI): • Intuitive Operation through Informative Overview and Detail Screens • Control and Monitoring of System Parameters • Control and Monitoring of Genset and Utility Parameters • Password Protection for Critical Settings • Alarm Logging and Annunciation • Circuit Breaker Control Switch with indication • Audible Alarm & Horn Silence Button • Emergency Stop Button for Each generator • Optional Sync Check Device EMCP3.S Control Technology Redundant Master Functionality High Speed Ethernet Supervisory Network Automatic Start/Stop Automatic Load and VAR Sharing Automatic “Dead Bus” Coordination Automatic Power Factor Control When in Parallel with Utility Power Programmable Load Shed / Load Add Functions Networked Engine Communications (requires Cat EMCP3.2, 3.3, 4.2) Generator and Util

SWITCHGEAR GENERATOR BREAKER PANEL (GBP1 or GBP2) The Generator Breaker Panel (GBP) provides for interconnection of (1) or (2) additional engine generators to the system. The GBP houses the electrically operated circuit breakers for one or two incremental engine generators, and can be combined with the MBP in modular arrangements for up to a total of ten engines in parallel. Load take-off lugs or crossbuss are available power flow options. These structures include the generator controls for their respective generators, GENERATOR BREAKER PANEL (GBP2) • Controls One Incremental Cat Generator Set...

DISTRIBUTION BREAKER PANELS EGIS feeder panels and load feeders are modular and expandable up to 24 controlled loads. Distribution control and load shed level prioritization are accomplished through the HMI control screen on the Master Breaker Panel. DISTRIBUTION BREAKER PANEL MASTER DISTRIBUTION BREAKER PANEL SLAVE • EMCP3.S Master Controls up to 24 Load Feeder Circuit Breakers (3 provided in structure) • Each Slave Panel Contains Three Distribution Breakers • I/O Module for Control of up to 3 Circuit Breakers in each Slave Panel
