System Description and Specifications 1.0 Scope Provides a general description of the Comet 40-150kV A Uninterruptible Power Systems major components, available options, and system specifications.
Figure 1-3, and 1-4 show single-line diagrams of a typical UPS system installation. During normal operation, utility power (Main Input) is supplied to the UPS Rectifier where it is converted to DC voltage. The Inverter converts the DC voltage from the Rectifier to three-phase regulated AC voltage, which supplies the critical load.
Installation and User Manual 1.2 Major Components The following is a description of the cabinets and major components. Refer to Figures 1-5 to 1-8. UPS Cabinet Converts the input AC power to direct current and charges the battery . DC power is converted back to clean AC power by the inverter for the critical load.

Installation 2.0 Scope Installation of the Comet 40-150kV A UPS, which include receiving, handling, and storage procedures; prerequisites to installation; installation procedures; and startup procedures. CAUTION Scheduling of the MGE Field Service Engineers typically should be done 7 to 10 days before they are required on-site.
If the equipment is to be stored for more than three months before installation, it should be unpacked and connected to an AC input source to allow the batteries to be recharged. Refer to the installation instructions that follow , and the installation drawings.
Installation and User Manual 2.4.2 Mechanical The Comet UPS can be mounted on a raised computer room floor , or flush-mounted on a concrete floor . All floors must be level. On a raised floor , conduits can be run below the floor , with cut-outs made in the floor tiles as shown on the installation drawings.
2.5 Installation Procedures The steps to be followed are: ◗ Placement of the UPS and associated equipment. ◗ Connection of input power , output power , and control cables. Installation of UPS equipment must be handled by skilled technicians and electrician's familiar with the special requirements of high-energy electrical equipment.
Installation and User Manual 2.6.4 AC Output The connections to be made are the three phases, and ground cables from the load source to the UPS. The output cables are terminated at the Output T erminal Block (TB2) for 40-80kV A, and the output busbars for 100- 150kV A.

Operation 3.0 Scope Important information on the Comet 40-150kV A systems’ operation procedure sequences; for normal, on battery , and bypass operation, with descriptions of the control and display indicators.
3.1.3 Power Flow , For Bypass Operation Should there be an internal fault in the UPS, the load will automatically be transferred to the "Static Switch". (If bypass AC input is within tolerance). The load is supplied without interruption while the UPS is bypassed (see Figure 3-3).
Installation and User Manual Figure 3-4: Comet Front Panel GUI, Controls and Indicators. NOTE For details on the Graphical User Interface (GUI) display , please refer to manual 86-160316-00.
Graphical User This display provides specific information concerning normal UPS operation as Interface Display well as faults. Emergency Power Off This red Emergency Power Off (EPO) pushbutton is used to stop the unit during an emergency situation only .
Installation and User Manual 3.3 Startup Procedures 3.3.1 Preliminary Checks ◗ Check the settings of the protection devices. ◗ V erify that the battery circuit breaker(s) are in the "OFF" position. ◗ V erify that the Manual Bypass Switch SR1 is set to the “NORMAL” position.
3.5 Operating Procedures 3.5.1 Normal Operation ◗ The AC input power is present. ◗ The green "Load Protected" LED is on. The GUI display indicates the operating status of the UPS. ◗ The power drawn by the load is supplied by AC input power via the Rectifier and Inverter modules.
Installation and User Manual 3.5.4 Overload When an Inverter temporary overload occurs, the load is transferred to the "Static Switch". Return to normal mode of operation is automatic, following elimination of the overload.
3.6 Emergency Shutdown Using EPO/REPO CAUTION Pressing the “Emergency Power Off” (EPO) or “Remote Emergency Power Off” (REPO) pushbutton disconnects the attached load. The EPO is to be used during emergency situations only , where a hazard to personnel or equipment exists, such as during a fire.
Installation and User Manual NOTE The cooling fans will remain operational when the UPS is placed on Maintenance Bypass mode to prevent the optional input/output transformers inside the UPS from overheating. If it is necessary to de-energize the fans, move the fan control switch (SR2) to the “OFF” position.
3.9 Shutdown Procedures 3.9.1 Inverter Shutdown ◗ Press and hold the gray "Inverter OFF" pushbutton for 3 seconds. ◗ The green “Load Protected” LED goes off. ◗ The red “Load Not Protected” LED goes on. ◗ The buzzer sounds. ◗ The Inverter stops if the transfer conditions are correct.
