8. GROUNDING.
• The PureWave CES base must be connected to a
suitable earth ground for testing before energizing
the unit, and at all times when energized.
• The ground wire(s) must be bonded to the sys-
tem neutral, if present. If the system neutral is not
present, proper precautions must be taken to ensure
that the local earth ground, or building ground,
cannot be severed or removed.
• The overall ground system should be sufficient to limit
the Ground Potential Rise (GPR), step voltage, and
touch voltage to acceptable limits as determined by
the utility’s practices and the National Electric Safety
Code (NESC).
9. ENERGIZED COMPONENTS. Always consider all
parts live until de-energized, tested, and grounded. For
visible battery disconnection from the PureWave CES,
see Figure 3 on page 6 for location of terminals.
10. INSULATED HAND TOOLS.
• Insulated hand tools are required when working on or
around any energized equipment. Use only properly
rated tools for the energy present.
• Tool inventories should be kept to ensure that all tools
that enter the system enclosure are removed prior to
energizing the system.
11. EMERGENCY PROCEDURES AND EQUIPMENT.
• The owner should develop policies and procedures
for handling emergency situations.
• It is the responsibility of the owner to develop
site-specic emergency action plans for response
to such situations.
12. ADDITIONAL SAFETY INSTRUCTIONS. Consult the
battery supplier for additional safety instructions and
procedures regarding the battery used in the PureWave
CES.
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.

6S&C Instruction Sheet 658-500
Safety Information
Equipment Safety
Precautions and
Practices
S&C PureWave CES and battery instruction sheets must be available to all operators and
other employees. If doors to the system enclosure must be opened, refer to the instruc-
tion sheet for procedures for guarding against electric shock. All enclosure doors must
be padlocked when authorized personnel are not present to prevent injury to persons
unaware of the risks associated with the system.
WARNING
For safety, the PureWave CES has been designed as an unmanned device.
No person should attempt to defeat any interlock or other safety device and open any
PureWave CES access panels while the unit is running, the isolation breakers are closed,
or there is greater than 50V on the DC link or the battery input.
The user should not attempt to connect any additional logic controls or power connec-
tions to the PureWave CES without having received written approval from S&C Electric
Company.
Shield Protection The PureWave CES contains protection for the end-user from exposure to potentially
dangerous components of the unit. Figure 1 shows the shielding protection from the line
connections (at the front of the unit). Figure 2 shows the protection from the DC wiring
(at the back of the unit).
Figure 1. Shield protection from wiring
(front of unit).
Figure 2. Shield protection from line
connections (back of unit).
Visible Battery
Disconnect Terminals
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
is here that the end-user can connect/break the connection between the unit and the bat-
tery. This ensures the operator has a visible means to proceed in taking steps to operate
the unit (when connected), or take the steps needed to service the unit (when discon-
nected). See Figure 3.
Figure 3.Visible battery non-load-break
disconnect terminals.

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.
In the “REMOVE FROM SERVICE” control mode, the AC and DC breakers are opened
(if not already open). The inverter is inhibited. The “IN SERVICE” LED is off. The unit
will not respond to local or SCADA real or reactive power commands. If the control is
powered up and communications are functioning, unit status is available through DNP
points to local and/or SCADA applications. The unit will save updates to local and SCADA
commands, but will not respond to them.
When the selector switch is moved from “REMOVE FROM SERVICE” to “SCADA DIS-
ABLE,” the “IN SERVICE” LED is lighted. The unit will respond to local energy dispatch
commands. The unit will save updates to SCADA commands, but will not respond to them.
When the selector switch is moved from “SCADA DISABLE” to “SCADA ENABLE,”
any previously stored SCADA command is initiated (real or reactive power flow in or
out). The “IN SERVICE” LED is lighted. The unit will respond to SCADA energy dispatch
commands. The unit will save updates to local commands, but will not respond to them.
Indicator Lights Five LEDs indicate the status of the PureWave CES unit:
1. SCADA ENABLE – A yellow LED that illuminates when rotary switch is in the “SCADA
ENABLE” position. The unit is in SCADA mode.
2. SCADA DISABLE – A yellow LED that illuminates when rotary switch is in the
“SCADA DISABLE” position. The unit can be operated via the IntelliLink program.
3. IN SERVICE – A green LED that illuminates whenever the rotary switch is not in the
“REMOVE FROM SERVICE” position.
4. ALARM – A red LED that illuminates whenever an alarm or warning is present.
5. DISCHARGE – A red LED that illuminates whenever the discharge connector is
installed.
Controls and Indicators

8S&C Instruction Sheet 658-500
Reset Button The reset button has two functions: resetting alarms and powering down the unit
controls.
The presence of alarms is indicated by the alarm LED. Pressing the reset button (black
push-button) will cause the unit to attempt to reset any active alarms. 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.
Hot Start Button If the unit controls are shut down, they may be restarted without the presence of AC
power. The user can provide a “jump start” using a 24-VDC battery connected to the
24-VDC terminals that are located under the selector switch on the control panel (refer
back to Figure 5 for 24-VDC input locations). Then press the hot start button (red push-
button). This action only powers controls for investigation; the system will not power
the load without the utility source present.
Discharge Connector The DC test points and discharge connector are mounted below the selector switch on
the control panel. These are used to discharge the DC bus capacitors and to test to that
a safe voltage level has been reached so that the unit may be serviced. Refer to Figure 5
for location of components to discharge the PureWave CES.
To discharge the DC bus capacitors:
• Place the selector switch in the “REMOVE FROM SERVICE” position.
• Install the DC voltage meter leads in the test points.
• Install the discharge jumper into the discharge connector.
• Observe the DC voltage meters to ensure that the DC bus capacitors discharge below
50 VDC in approximately ve (5) minutes.

points
Figure 5. Discharging the PureWave CES.
DANGER
Keep the shorting jumper installed during any service operation. This will discharge the
energy from the electrolytic capacitors.
Failure to install the shorting jumper may result in electric shock from the DC bus.
Controls and Indicators

S&C Instruction Sheet 658-500 9
Controls and Indicators
The DC bus capacitor test points are red, white, and black.
• The black test point is connected to DC (-).
• The white test point is connected to the DC midpoint
• The red test point is connected to DC (+)
Capacitors are connected from DC (+) to midpoint and from DC (-) to midpoint. Use
these test points to monitor the DC bus voltage while the discharge jumper is installed
to verify that the voltage has been discharged to a safe level for entry and service.
Note the locations of the DC test points and the 24-VDC alternate supply points to
avoid confusion.
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. Below is the description of each state.
Table 1. Operating States of the PureWave CES
States Description
Program Reset This state indicates that the program is initialized. This state also only occurs at
power up.
Inhibit This state indicates that there is a problem that needs attention and will affect
the proper operation of the system. The system will stop operating when an
INHIBIT is being displayed on the IntelliLink program. The AC breaker will
remain closed during this state.
Trip Offline This state indicates that there is a severe problem that needs attention and will
affect the proper operation of the system. The system will stop operating when
a TRIP OFFLINE is being displayed on the IntelliLink program. The AC breaker
will be open in this state.
Ready The state indicates that the PureWave CES is ready to protect the load in the
event of a utility disturbance.
VS Run This state indicates that the master control has commanded the PureWave
CES to run. Here, the inverter controls the AC voltage and the PureWave CES
is the power source in the event of a utility power outage.
CS Run This state indicates that the master control has commanded the PureWave
CES to run. Here, the inverter controls the AC current and the PureWave CES
provides the required real or reactive power for power smoothing.
Conserve Energy This state indicates that the battery is reducing power usage to prolong
the ability to run on the battery. This state is entered if the battery energy is
depleted and the utility source voltage is not present.
System Shutdown This state indicates that the battery energy is depleted. The system enters
“shutdown,” which turns the system off. The system will return to the “Ready”
state when the utility source power is restored and the batteries are charged.

10 S&C Instruction Sheet 658-500
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.
Table 2. Reset Types for the PureWave CES
Reset Type Description
Auto This type of reset will automatically be performed until a pre-determined reset
count has been reached.
The alarm is reset up to the limit defined by the Auto Reset TripCountMax
control parameter. When the number of Auto Reset attempts exceeds the
TripCountMax, the system goes to and remains in the ‘Trip Offline’ state until it
is reset manually by the operator.
Each alarm does not have its own Auto Reset Trip Counter. Rather, there
is only one counter, such that Auto Reset attempts from different alarms all
count against the same total. There is also an Auto Reset Trip Reset Timer that
starts counting down from five minutes every time an Auto Reset alarm occurs.
If the timer reaches zero before the maximum number of Auto Reset attempts
is exceeded, the Auto Reset Count is cleared. The Auto Reset Count is not
allowed to persist for more than five minutes.
Manual This type of reset will require a person to use the local user interface, a SCADA
connection, or push the RESET button on the control panel of the PureWave
CES to reset the system.
Self This type of reset will clear alarms when the alarm condition clears. No reset
counter is used.
Alarms The PureWave CES contains an extensive self-diagnosis system. If any abnormal condi-
tion occurs, the system will activate an alarm. Below is a list of alarms categorized by
alarm type. Alarm types are categorized as information, warning, inhibit, isolate, and
trip ofine.
CAUTION
All alarms should be handled by qualified personnel who are knowledgeable in
troubleshooting the PureWave CES. If there are any doubts about how to handle an
alarm event, please contact S&C Electric Company.

16 S&C Instruction Sheet 658-500
System Overview The PureWave CES shall function and operate as an intelligent distributed energy
storage system to help utilities meet their rapidly changing Smart Grid challenges. By
positioning discrete amounts of utility-controlled storage where needed throughout
their distribution system, the PureWave CES shall enable utilities to rapidly respond
to changing electricity-use patterns, integrate renewables, manage renewable resource
intermittency, manage peak loads including plug-in electric vehicle loads, and provide
reliable backup power within a fraction of a second for improved power quality. With
the PureWave CES system’s ability to provide high-speed transfer from the grid to bat-
tery power, outages are often barely perceptible to customers.
The PureWave CES is rated at 25 kW/25 kVA. Each PureWave CES unit shall consist of
1) a power conversion system (PCS) suitable for outdoor installation on a user-
furnished concrete pad or the user-furnished box pad, and
2) an energy storage unit consisting of either a select 25-kWh or 50-kWh lithium-
ion battery pack suitable for subsurface installation underneath the PCS, in a
user-furnished concrete vault. The PureWave CES shall be connected to the 120/
240 VAC split-phase secondary of a 25-kVA outdoor utility distribution transformer
(supplied by others) at a frequency either 50 Hz or 60 Hz.
The PCS shall consist of an inverter area housing an AC circuit breaker, an inverter,
user-accessible AC termination area, user-accessible DC termination area, and user-
accessible controls area.
System Design In normal operation, the PureWave CES shall operate in current-source mode, provid-
ing such functionality as voltage regulation, power factor correction, peak shaving, and
load following. If the utility power source is interrupted, the AC breaker in the unit shall
open, isolating and islanding the load from the utility source. The energy storage unit
and inverter shall then power the islanded load for up to either 1 hour with a 25-kWh
battery pack or 2 hours with a 50-kWh battery pack. The energy storage unit will sup-
port the load until utility service is resumed or the energy storage unit of the PureWave
CES is depleted. See Figure 6.

Entering the System
Enclosure WARNING
Do not enter the system enclosure unless trained, certified, and authorized to do so.
Potentially lethal voltages are present inside the system enclosure. High-voltage DC is
present even without the utility power connected.
The enclosure is meant to provide access for field troubleshooting purposes only when
the unit is properly grounded. Never, under any circumstances, open the enclosure doors
on the PureWave CES while it is online or has not been fully discharged and grounded.
The PureWave CES enclosure houses the control, inverter, and cable termination
areas. These areas can be accessed by unlocking all padlocks and opening the doors of
the enclosure using a penta-socket wrench. Location of the door locks and components
are illustrated in the following Figures 7, 8, and 9.

Energy Storage
System
The energy storage (batteries) component of the PureWave CES shall be designed and
constructed for installation underground in a vault, which shall be located directly
beneath the unit. The batteries shall be contained in a watertight NEMA Type 6P
enclosure, providing protection against water seepage and prolonged submersion at
installation depth. The battery pack shall include a battery monitoring system. See
Figure 10 for illustration. Please refer to the battery manufacturer manual for more
information.

2. Turn on the PC and set the computer to the xed IP on the same subnet as the Pure-
Wave CES add-on Ethernet port:
a. IP = 192.168.10.4
b. Mask = 255.255.255.0
c. No gateway
3. Find the IntelliLink icon and double-click on it to access the conguration screen.
The following are the conguration steps to the IntelliLink program. See Figure 12 on
page 20 for location of the elds to enter the data:
a. Destination DNP address = as congured in unit (default = 12)
b. Connection Type = UDP/IP
c. Peer IP = 192.168.10.2
d. Peer port = 20000
e. Our Port = 20001 (if SCADA is used on the same PC in the UDP channel denition,
the value must be different).
f. Click on the “IntelliLink” button to connect.
