During installation, operation, maintenance or service, individuals may be exposed to certain components or conditions including, but not limited to: refrigerants, oils, materials under pressure, rotating components, and both high and low voltage. Each of these items has the potential, if misused or handled improperly, to cause bodily injury or death. It is the obligation and responsibility of operating/service personnel to identify and recognize these inherent hazards, protect themselves, and proceed safely in completing their tasks. Failure to comply with any of these requirements could result in serious damage to the equipment and the property  \nin which it is situated, as well as severe personal injury or death to themselves and people at the site.  \nThis document is intended for use by owner-authorized operating/service personnel. It is expected that this individual possesses independent training that will enable them to perform their assigned tasks properly and safely. It is essential that, prior to performing any task on this equipment, this individual shall have read and understood this document and any referenced materials. This individual shall also be familiar with and comply with all applicable governmental standards and regulations pertaining to the task in question.  \nsafetY sYmBols  \nThe following symbols are used in this document to alert the reader to areas of potential hazard:  \nDANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.  \nWARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.  \nCAUTION identifies a hazard which could lead to damage to the machine, damage to other equipment and/or environmental pollution. Usually an instruction will be given, together with a brief explanation.  \nNotE is used to highlight additional information which may be helpful to you.  \nExternal wiring, unless specified as an optional connection in the manufacturer’s product line, isNot to be connected inside the micro panel cabinet. Devices such as relays, switches, transducers and controls may Not be installed inside the micro panel. No external wiring is allowed to be run through the micro panel. All wiring must be in accordance with Johnson Controls published specifications and must be performed oNly by qualified Johnson Controls personnel. Johnson Controls will not be responsible for damages/problems resulting from improper connections to the controls or application of improper control signals. Failure to follow this will void the manufacturer’s warranty and cause serious damage to property or injury to persons.  \n2 JOHNSON CONTROLS  \nFORM 160.75-O1  \nchangeaBilitY of this document  \nIn complying with Johnson Controls policy for continuous product improvement, the information contained in this document is subject to change without notice.
