1. QUALIFIED PERSONS. Access to the PureWave
SMS-250 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 flame-

voltages should also be expected in all interconnecting
components and lines.
To maintain safety, the user should use a padlock on
the door of the power conversion system. The door and
the use of the padlock provide protection to inadvertent
contact with hazardous voltages.
