FORM 201.23-NM2ISSUE DATE: 3/9/2015IMPORTANT!READ BEFORE PROCEEDING!GENERAL SAFETY GUIDELINESThis equipment is a relatively complicated apparatus.During rigging, installation, operation, maintenance,or service, individuals may be exposed to certain components or conditions including, but not limited to:heavy objects, refrigerants, materials under pressure,rotating components, and both high and low voltage.Each of these items has the potential, if misused orhandled improperly, to cause bodily injury or death. Itis the obligation and responsibility of rigging, installation, and operating/service personnel to identify andrecognize these inherent hazards, protect themselves,and proceed safely in completing their tasks. Failureto comply with any of these requirements could resultin serious damage to the equipment and the property inwhich it is situated, as well as severe personal injury ordeath to themselves and people at the site.This document is intended for use by owner-authorizedrigging, installation, and operating/service personnel. Itis expected that these individuals possess independenttraining that will enable them to perform their assignedtasks properly and safely. It is essential that, prior toperforming any task on this equipment, this individualshall have read and understood the on-product labels,this document and any referenced materials. This individual shall also be familiar with and comply withall applicable industry and governmental standards andregulations pertaining to the task in question.SAFETY SYMBOLSThe following symbols are used in this document to alert the reader to specific situations:Indicates a possible hazardous situationwhich will result in death or serious injuryif proper care is not taken.Identifies a hazard which could lead todamage to the machine, damage to otherequipment and/or environmental pollution if proper care is not taken or instructions and are not followed.Indicates a potentially hazardous situation which will result in possible injuriesor damage to equipment if proper care isnot taken.Highlights additional information usefulto the technician in completing the workbeing performed properly.External wiring, unless specified as an optional connection in the manufacturer’s product line, is notto be connected inside the control cabinet. Devices such as relays, switches, transducers and controlsand any external wiring must not be installed inside the micro panel. All wiring must be in accordance with Johnson Controls’ published specifications and must be performed only by a qualifiedelectrician. Johnson Controls will NOT be responsible for damage/problems resulting from improperconnections to the controls or application of improper control signals. Failure to follow this warning will void the manufacturer’s warranty and cause serious damage to property or personal injury.2JOHNSON CONTROLS

FORM 201.23-NM2ISSUE DATE: 3/9/2015CHANGEABILITY OF THIS DOCUMENTIn complying with Johnson Controls’ policy for continuous product improvement, the information contained in this document is subject to change withoutnotice. Johnson Controls makes no commitment toupdate or provide current information automaticallyto the manual or product owner. Updated manuals, ifapplicable, can be obtained by contacting the nearestJohnson Controls Service office or accessing the Johnson Controls QuickLIT website at http://cgproducts.johnsoncontrols.com.It is the responsibility of rigging, lifting, and operating/service personnel to verify the applicability of thesedocuments to the equipment. If there is any questionThe Control/VSD Cabinet contains lethalhigh AC and DC voltages. Before performing service inside the cabinet, removethe AC supply feeding the chiller andverify using a non-contact voltage sensor.The DC voltage on the VSD DC Bus willtake 5 minutes to bleed off, after ACpower is removed. Always check the DCBus Voltage with a Voltmeter to assurethe capacitor charge has bled off beforeworking on the system.NEVER short out the DC Bus to discharge the filter capacitors.regarding the applicability of these documents, rigging, lifting, and operating/service personnel shouldverify whether the equipment has been modified andif current literature is available from the owner of theequipment prior to performing any work on the chiller.CHANGE BARSRevisions made to this document are indicated with aline along the left or right hand column in the area therevision was made. These revisions are to technical information and any other changes in spelling, grammaror formatting are not included.NEVER place loose tools, debris, or anyobjects inside the Control Panel/VSDCabinet.NEVER allow the Control Panel VSDCabinet doors to remain open if there isa potential for rain to enter the panel.Keep doors closed and assure all latches are engaged on each door unless theunit is being serviced.ALWAYS lockout the disconnect supplying AC to the chiller.The 1L Line Inductor will reach operatingtemperatures of over 300 F. DO NOTopen panel doors during operation. Assure the inductor is cool whenever working near the inductor with power OFF.JOHNSON CONTROLS3
