4、uipment unless there is another person nearby who is familiar with the operation and hazards of the equipment and who is competent in administering first aid. When the technician is aided by operator s, he must warn them about dangerous areas. Whenever possible, the power supply to the equipment mus

5、t be shut off before beginning work on the equipment. Take particular care to ground every capacitor likely to hold a dangerous potential. When working inside the equipment, after the power has been turned off, always ground every part before touching it. Be careful not to contact high-voltage conne

6、ctions or 115 volt ac input connections when installing or operating this equipment. Whenever the nature of the operation permits, keep one hand away from the equipment to reduce the hazard of current flowing through the body. Warning: Do not be misled by the term “low voltage.” Potentials as low as

7、 50 volts may cause death under adverse conditions. For Artificial Respiration, refer to FM 21-11. B TM 11-5820-919-40-2 SAFETY SUMMARY The following are general safety precautions that are not related to any specific procedures and therefore do not appear elsewhere in this publication. These are re

8、commended precautions that personnel must understand and apply during many phases of operation and maintenance. KEEP AWAY FROM LIVE CIRCUITS Operating personnel must at all times observe all safety regulations. Unless specifically directed in this manual, do not replace components or make adjustment

9、s inside the equipment with any power supply turned on. Under certain conditions, dangerous potentials may exist in the power supplies when the power control is in the off position. To avoid causalities, always remove power and discharge and ground a circuit before touching it. DO NOT SERVICE OR ADJ

10、UST ALONE Under no circumstances should any person reach into or enter the enclosure for the purpose of servicing or adjusting the equipment except in the presence of someone who is capable of rendering aid. RESUSCITATION FIRST AID Each person engaged in electrical operations will be trained in firs

11、t aid, particularly in the technique of mouth to mouth resuscitation and closed chest heart massage (FM 21-11). The following warnings appear in this volume, and are repeated here for emphasis. WARNING A 3-wire (line, neutral, and safety ground) AC line power connections is required when operating t

12、he equipment. If a 3-wire safety grounded AC power receptacle is not available, a separate ground wire must be installed from the chassis ground to an earth ground. Without an adequate ground, the equipment chassis and frame will float to a dangerously high potential. WARNING Lethal voltage is used

13、in the operational checkout of this unit. Death on contact may result if personnel fail to observe the following safety precautions. Remove watches and rings and exercise extreme caution when working inside the equipment throughout the remainder of this procedure. C TM 11-5820-919-40-2 WARNING Prior

14、 to performing the following functions all electrical power is to be removed from the system. External power disconnected and a MAINTENANCE IN PROGRESS tag attached or power switches will be locked out to prevent inadvertent energizing of the system. WARNING Lifting heavy equipment incorrectly can c

15、ause serious injury. Do not try to lift more than 35 pounds by yourself. Get a helper. Bend legs while lifting. Dont support heavy weight with your back.
