Page 13: Safety Precautions
Safety Precautions DANGER The S&C PureWave UPS System operates at high ac and dc voltages. Failure to observe these precautions will result in serious personal injury or death. Some of these precautions may differ from your company’s operating procedures and rules.
Page 14: Components And Controls
Do not enter the system enclosure unless trained, certified, and authorized to do so by S&C Electric Company. Physical entry into the PureWave UPS System should never be attempted while the system is enabled or when the modules are online. Voltages up to 800 Vdc and 600 Vac should be expected under normal operating conditions.

Page 16: Enclosure Bays
Components and Controls Enclosure Bays The enclosure of the PureWave UPS System consists of three types of bays: Battery bay—Each battery bay contains a 250-kW battery module and a power conver- sion module (PCM). The PCM is located in its own compartment in the battery bay and is comprised of one inverter module consisting of power-conversion electronics and con- trols.

Page 18 Components and Controls Enclosure Bays − Control bay—The control bay houses the monitoring computer, control system, power continued electronic switch (PES), and ac filter capacitor. In addition, an EMERGENCY DISABLE mushroom switch and a RESET pushbutton are located behind the door. See Figure 8 for a view of the control bay.
Page 19: Doors
Components and Controls Doors To open a bay door, remove the padlock from the security cover located over the center bolt. Three bolts (top, center, and bottom) secure the door closed. Loosen the three bolts so they detach from the enclosure (the bolt will not completely detach from the door).
Page 20: Lcd Screen
LCD screen Next to the control bay is the LCD screen, which displays information regarding the state of the PureWave UPS System. See Figure 10. The bottom line of the LCD screen displays the general messages as stated in Table 1.

Page 23: Service Personnel Controls
Components and Controls Service Personnel In addition to the operating controls located inside the switchgear bay, redundant oper- ating controls are located in the control bay. These controls are intended to be used by Controls authorized service personnel. See Figure 13 for the location of these controls. ENABLE/DISABLE–This mushroom pushbutton performs the same functionality as the toggle switch in the switchgear bay.
Page 24: Monitoring Computer
The monitoring computer is used to log system events and to monitor the status of the PureWave UPS System. The computer is located on the back of the swing-out panel located in the control bay. Information from the computer can be accessed via an Ether- net connection.
Page 25: Contacts
Run state. Remote Disable If supplied, a normally closed input contact must be provided by the user to the PureWave UPS System. Upon opening of the input contact, the system will go to the Bypass state, (Optional) and an output contact will close to indicate the system has been remotely disabled.
Page 26: Operation
An electrically operated bypass circuit breaker permits continued service to the customer from the utility in the event the PureWave UPS System is out of service for maintenance. See Figure 15 for a diagram of the PureWave UPS System.
Page 27: States
In this state, the PureWave UPS System is ready to protect the load in the event of a disturbance. In this state, the PureWave UPS System is running to protect the load from a utility disturbance. The inverters are on and the PES is open.
Page 28: Alarms List And Troubleshooting Tips
Operation Alarms List and The PureWave UPS System contains an extensive self-diagnosis system. If any abnormal condition occurs or if the system cannot protect the load from a disturbance, the system Troubleshooting Tips will activate an alarm. The alarms can be categorized by alarm type. Alarm types are cat- egorized as Warning, Inhibit, Bypass, and Bypass Isolate.
Page 29: Inhibit Alarms
Load Over Current Indicates the load current has exceeded 115% of the current rating of the system Troubleshooting Tip: Check the load against what the PureWave UPS System was sized for. Load Over Power Indicates the load power has exceeded 115% of the power rating of the system Troubleshooting Tip: Check the load against what the PureWave UPS System was sized for.
Page 30: Bypass Alarms
Operation Bypass Alarms A Bypass alarm indicates a condition that requires attention and places the system in the Bypass state. The system is not available to protect the load from power disturbances. See Table 6 for the listed Bypass alarms. Table 6.
Page 31: Start-Up
Procedure PureWave UPS can be placed in the Bypass Isolate state via the following procedure: Make sure the ENABLE/DISABLE selector switch is turned to the Disable STEP 1.
Page 32: Battery Charging
The PureWave UPS System will go into the Run state while the transfer switch STEP 9. returns the critical load to the utility. If the load is at 50% or less of the PureWave UPS System rating, the system will wait for 10 seconds before actuating the transfer signal. S&C Instruction Sheet 653-502...
Page 33: Monitoring
Monitoring Overview The PureWave UPS System can be monitored in three ways. The system can be monitored through the LCD screen display, through the computer provided in the control bay via a local connection, and remotely using an Ethernet connection.
Page 34 Monitoring Monitoring Software − Icons — continued continued Utility source–If this icon is red, it indicates the utility is a good source. If the icon is green, it indicates the utility is not good (the source is not within voltage and frequency tolerance).
