  • Page 2: Introduction

    PDF format at sandc.com/Support/ Product-Literature.asp Retain this This instruction sheet is a permanent part of your PureWave CES. It does not include instruction sheets from the original battery manufacturer and the IntelliLink® Remote Instruction Sheet Setup Software.

  • Page 3: Safety Information

    Understanding There are several types of safety-alert messages which may appear throughout this instruction sheet as well as on labels attached to the PureWave CES System. Familiarize Safety-Alert yourself with these types of messages and the importance of the various signal words, as Messages explained below.

  • Page 4: Location Of Safety Labels

    PE-70314 Annual Inspections After the PureWave CES is commissioned and the unit is on-line, inspection and main- tenance should be scheduled on an annual basis to ensure the proper operation of the system. Schedules for maintenance should be reviewed by the customer based upon the given site conditions and, if required, the frequency of the recommended maintenance should increase to ensure the reliability of their PureWave CES.
  • Page 5 Safety Information DANGER The PureWave CES operates at high voltage. Failure to observe the precautions below will result in serious personal injury or death. Some of these precautions may differ from your company’s operating procedures and rules . Where a discrepancy exists, follow your company’s operating procedures and rules .

    (front of unit). connections (back of unit). Visible Battery The PureWave CES provides a means to disconnect the battery from the unit. At the rear of the unit, there are two non-load-break disconnect terminals (positive and negative). It Disconnect Terminals is here that the end-user can connect/break the connection between the unit and the bat- tery.

    DC discharge connector Figure 4. Control panel. Selector Switch A three-position rotary switch selects between three control modes of the PureWave CES unit: 1. SCADA ENABLE – Fully counter-clockwise position. 2. SCADA DISABLE – Center position. 3. REMOVE FROM SERVICE – Fully clockwise position.

  • Page 8: Reset Button

    If all alarms are successfully cleared, the alarm LED will turn off. To power down all PureWave CES unit controls, remove the utility source and turn the selector switch to “REMOVE FROM SERVICE.” Then press and hold the reset button for 14 seconds.

  • Page 9: States

    States Listed in Table 1 are the eight operating states of the PureWave CES. The IntelliLink program will inform the user what state the system is currently in. Depending on the alarm condition encountered, the community energy storage system can be in any of these states.

  • Page 10: Resets

    Controls and Indicators Resets In order to clear an alarm condition, the PureWave CES will require a “reset” to set the unit to the “Ready” state. This enables the community energy storage system to be ready for another event should one occur. Table 2 lists the three resets available for the PureWave CES: Auto, Manual, and Self.
