Model IIIPackage Substations Class 6010 Instruction Bulletin Retain for future use. HAZARD CATEGORIES AND SPECIAL SYMBOLS Read these instructions carefully and look at the equipment to become familiar with the device before trying to install, operate, service, or maintain it. The following special messages may appear throughout this bulletin or on the equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a procedure. The addition of either symbol to a “Danger” or “Warning” safety label indicates that an electrical hazard exists which will result in personal injury if the instructions are not followed. This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death. ENGLISH DANGER DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING WARNING indicates a potentially hazardous situation which, if not avoided, can result in death or serious injury. CAUTION CAUTION indicates a potentially hazardous situation which, if not avoided, can result in minor or moderate injury. CAUTION CAUTION, used without the safety alert symbol, indicates a potentially hazardous situation which, if not avoided, can result in property damage. NOTE: Provides additional information to clarify or simplify a procedure. PLEASE NOTE Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel.

Schneider Electric recommends that you do not place the substation directly on an earthen surface. 24-hours a day. Follow all local and national codes when locating the substation. Make sure the ventilated openings. on the top and bottom of the enclosure. see “Changing Tap Positions to Adjust Voltage” on page 20. They can provide assistance in a variety of areas. Locate the substation on a level foundation strong enough to support the weight of the substation. If the substation is located near combustible materials. Use leads that are long enough to avoid mechanical strain caused by expansion and contraction. DANGER HAZARD OF ELECTRIC SHOCK. Failure to follow this instruction will result in death or serious injury. make sure the location meets or exceeds the minimum clearances as required by the National Electric Code® (NEC®) or other applicable local codes.
