Engineering Information IMPORTANT SAFETY INSTRUCTIONS These instructions are intended to be used as a general guide to provide basic instal- lation information which is necessary for the proper and safe functioning of this equip- ment. WARNING: Failure to follow all instructions may result in improper equipment operation and/or the risk of electric shock. General . . Read and understand all instructions. Keep these instructions with the equipment. Do not attempt to install or service this equipment unless you are skilled in the installation and maintenance of electronic telecommunication equipment and have successfully completed specific training for this equipment. This product must be installed and serviced in accordance with this document and the information contained in this set of technical practices. Practice Index ciocu- ments are 9109-098-501 -NA, 9109-098-502-NA, and 9109-098-503-NA. Follow all the steps outlined in this document in the sequence that is given. Configure this product only with the assemblies specified and in the locations stated in this document and in this set of technical practices. Replace all guards or barriers. Close and lock doors at the completion of instal- lation or before returning the equipment to service. Grounding circuit continuity is vital for safe operation of telecommunication equip- ment. Never operate telecommunication equipment with the grounding conductor disconnected. Ensure that the grounding conductor is installed before connecting telecommunication cabling to any system. (See Note, below). Note: Ail cabinets must be unplugged from the ac mains during servicing. Unplugging an SX-200 ML cabinet means that the cabinet is ‘Cfloating”, and thus presenting a potential static problem. To reduce static susceptibility on an SX-200 ML cabinet, always attach the wrist strap from the cabinet being serviced, and immediately place any item removed from a node into an antistatic bag.

Engineering Information Installation of Telecommunication Wiring Telecommunication wiring to this product shall conform to all applicable safety and electrical wiring regulations. Installation of telecommunication wiring shall be per- formed by following precautions in accordance with standard industry practice. The precautions to be followed include: l Never install telephone wiring during a lightning storm. l Never install telephone jacks in wet locations unless the jack is specifically de- signed for wet locations. l Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. 9 Use caution when installing or modifying telephone lines. Use of Notices and Symbols The following information provides an explanation of the notices and symbols which appear on the product and in the practices for this product. Danger indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. pziii-l Warning indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Caution indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury and/or damage to the equipment or property A DANGEROUS VOLTAGE A I 0 INSTRUCTIONS 0 A- PROTECTIVE GROUNDING TERMINAL The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulatec “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a significant risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and main- tenance (servicing) instructions in the literature accompanying the product. The ground symbol within a circle identifies the terminal which is intended for connection to an external protective conductor. This connector must be connected to earth ground prior to mak- ing any other connections to the equipment. I Issue 1 Revision 0 March 1997
