Safety Information
Hazardous Voltages DANGER
Potentially lethal voltages are present inside the PureWave UPS System. Dc voltage
is present even without utility power connected. Hazardous voltages should also be
expected in all interconnecting components and lines.
Securing the
Enclosure
To maintain safety, the user should use padlocks on each enclosure door. The doors and
the use of the padlocks provide protection against inadvertent contact with high-voltage
circuits.
Safety Equipment,
Precautions, and
Practices
S&C PureWave UPS System and battery instruction sheets must be available to all
operators and other employees. If doors to the electrical controllers or panels to the
system enclosure must be opened, refer to the instruction sheet for procedures for
guarding against electric shock. Lockout and tagout procedures should be developed
and implemented in accordance with 29 CFR 1910.147.
WARNING
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 all tools that enter the system enclosure are removed before energizing the
system.
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-specic emergency action plans for
response to such situations.
Additional Safety
Instructions
Consult the supplier of the batteries for additional safety instructions and procedures.

Safety Precautions
1. QUALIFIED PERSONS. Access to the PureWave UPS
System must be restricted only to qualified persons. See
“Qualified Persons” on page 2.
2. SAFETY PROCEDURES. Always follow safe operating
procedures and rules.
3. PERSONAL PROTECTIVE EQUIPMENT. Always use
suitable protective equipment, such as rubber gloves,
rubber mats, hard hats, safety glasses, and flash
clothing, in accordance with safe operating procedures
and rules.
4. SAFETY LABELS. Do not remove or obscure any of
the “DANGER,” “WARNING,” “CAUTION,” or “NOTICE”
labels.
5. OPERATING MECHANISM AND BASE. The PureWave
UPS System contains fast-moving parts that can
severely injure fingers. Do not remove or disassemble
operating mechanism or circuit breakers or remove
access panels on the PureWave UPS System unless
directed by S&C Electric Company.
6. ENERGIZED COMPONENTS. Always consider all parts
live until de-energized, tested, and grounded.
7. GROUNDING.
For grounding purposes, the proceeding must be
followed:
• The PureWave UPS System PCS base must be
connected to a suitable earth ground or to a suitable
building ground for testing before energizing the unit
and at all times when energized.
8. MAINTAINING PROPER CLEARANCE. Always
maintain proper clearance from energized components.
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. Where a discrepancy exists, follow your company’s operating procedures and rules.
Inspection After the PureWave UPS System is commissioned and the unit is online, inspection and
maintenance should be scheduled on a regular basis to ensure proper system operation.

Enclosure
Configurations DANGER
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. Dc voltage
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
while it is online or has not been fully discharged and grounded. Failure to do this can
result in equipment damage, personal injury, or even death.
Figures 1 through 4 show the different enclosure congurations for the 250-kW, 500-kW,
750-kW, and 1000-kW PureWave UPS System enclosures, respectively

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. The PCM is panel-mounted and supported by a welded and bolted steel structural
base. See Figure 5 for a view of the battery bay.

Switchgear bay—The switchgear bay houses the bypass switchgear circuit breakers, the
ENABLE/DISABLE switch, the RESET pushbutton switch, and user connections. For the
250-kW and 500-kW systems, the switchgear bay is located on the side of the system. For
the 750-kW and 1000-kW systems, the switchgear bay is located at the front of the system.

Control bay—The control bay houses the monitoring computer, control system, power
electronic switch (PES), and ac lter 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.

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). The door will now open. Once the door is opened approximately 90 degrees or 135
degrees, engage the lock-bar at the bottom of the door to prevent the door accidentally
closing. See Figure 9. To close a door, disengage the lock-bar by lifting it and returning it
to its storage location. Swing the door closed. Tighten the three bolts to secure the door
and install the padlock.

Air Control
and Ventilation
Components such as air conditioners and air-inlet and -outlet vent/vent hoods are used
to regulate the air inside the enclosure. Periodic maintenance is required to ensure the
air conditioners, air-inlet lter, vents, and hoods are clear from debris or obstructions
that can restrict air owing in and out of the PureWave UPS System enclosure. Refer
to the maintenance instruction sheet for detailed instructions for proper air ventilation
maintenance.
