S&C Instruction Sheet 658-500 5
Safety Information
1. QUALIFIED PERSONS. Access to PureWave CES 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. ENCLOSURE. Do not open access doors unless the
system is offline or otherwise authorized by S&C Electric
Company.
6. MAINTAINING PROPER CLEARANCE. Always
maintain proper clearance from energized components.
Ensure that the shield protectors inside the PureWave
CES are in place. See Figures 1 and 2 on page 6.
7. HIGH VOLTAGES. High-voltage DC is present
even without utility power connected. Hazardous
voltages should also be expected in all interconnecting
components and lines.
To maintain safety, the user should use padlocks on
each door of the PureWave CES.The door and the use
of the padlock provide protection to inadvertent contact
with high-voltage circuits.
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.
