Screen Service SDT 501 UB-C ARK 1-T General information May , 2010 v 1.0 Page 1 - 2 1.1 SAFETY SUGGESTIONS Regardless of how well electrical equipment is designed, personnel can be exposed to dangerous electrical shock when protective covers are removed for maintenance or other activities. Therefore, it is incumbent on the user to see that all safety regulations are consistently observed and that each individual assigned to the equipment has a clear understanding of the first aid related to electrical shocks. (see next pages) In addition these safety practices must be followed:  Do not attempt to adjust unprotected circuit controls or to dress leads with power on.  Always avoid placing parts of the body in series between ground and circuit points.  To avoid burns, do not touch heavily loaded or overheated components without precautions.  Remember that some semiconductor cases and solid-state circuits carry high voltages.  Do not assume that all danger of electrical shock is removed when the power is off. Charged capacitors can retain dangerous voltages for a long time after power is turned off. These capacitors should be discharged trough a suitable resistor before any circuit points are touched.  Don't take chances. Be fully trained. Screen Service Italia equipment should be operated and maintained by fully qualified personnel.  Do not service alone and do not perform internal adjustments of this unit unless another person capable of rendering first aid and resuscitation is present.  Some components used in the construction of this equipment contain Beryllium Oxide (BeO). This substance is harmless as it is, but becomes highly dangerous if it is ground to powder. Special procedures of disposal must be observed in case of failure of these devices. NOTE: This section is not intended to contain a complete statement of all safety precautions which should be observed by personnel in using this electronic equipment or others. Screen Service shall not be responsible for injury or damage resulted from improper procedures or from using it by improperly trained or inexperienced personnel.
Screen Service SDT 501 UB-C ARK 1-T General information May , 2010 v 1.0 Page 1 - 3 1.2 GENERAL SAFETY RECOMMENDATIONS When connecting the equipment to the power, please follow these important recommendations:  This product is intended to operate from a power source that will not apply more than 10% of the voltage specified on the rear panel between the supply conductors or between either supply conductor and ground. A protective-ground connection by way of the grounding conductor in the power cord is essential for safe operation.  This equipment is grounded through the grounding conductor of the power cord. To avoid electrical shock, plug the power cord into a properly wired socket before connecting to the product input or output terminals.  Upon loss of the protective-ground connection, all accessible conductive parts (including parts that may appear to be insulating) can render an electric shock.  To avoid fire hazard, use only the fuse of correct type, voltage rating, and current rating. Refer fuse replacement to qualified service personnel.  To avoid explosion, do not operate this equipment in an explosive atmosphere.  To avoid personal injury, do not remove the product covers or panels. Do not operate the product without the covers and panels properly installed. 1.3 GOOD PRACTICES In maintaining the equipment covered in this manual, please keep in mind the following, standard good practices:  At regular intervals, the condition of the equipment and the correct functioning of protective and safety devices shall be checked by a skilled person approved by the appropriate authority for this duty. Functional checks shall be carried out on interlocking systems of doors, mechanical interlocks, isolating switches, earthing switches, parallel resistances and protective devices against over-voltages and over-currents. The above checks shall not be carried out after the protective and safety devices have operated under fault conditions. The safety devices shall not be altered or disconnected except for replacement, nor shall the safety circuit be modified without specific approval of the appropriate authority in each case.  When connecting any instrument (wattmeter, spectrum analyzer, etc.) to a high frequency output, use the appropriate attenuator or dummy load to protect the final amplifiers and the instrument input.  When inserting or removing printed circuit boards (PCBs), cable connectors, or fuses, always turn off power to the affected portion of the equipment. After power is removed, allow sufficient time for the power supplies to bleed down before reinserting PCBs.  When troubleshooting, remember that FETs and other metal-oxide semiconductor (MOS) devices may appear defective because of leakage between traces or component leads on the printed circuit board. Clean the printed circuit board and recheck the MOS device before assuming it is defective.  When replacing MOS devices, follow standard practices to avoid damage caused by static charges and soldering.  When removing components from PCBs (particularly ICs), use care to avoid damaging PCB traces.
Screen Service SDT 501 UB-C ARK 1-T General information May , 2010 v 1.0 Page 1 - 4 1.4 PROCEDURE FOR ESTABLISH THE ABSENCE OF VOLTAGE Follow these simple steps for establish the absence of voltage:  Before starting work on the equipment, it shall be isolated from the mains supply. This disconnection shall always be checked by visual inspection. Further precautions shall be taken to ensure that the mains supp!y cannot be restored whilst work is being carried out. After the mains supply has been disconnected, all other lines such as control, interlocking and modulation lines shall be disconnected if they carry dangerous voltages. Moreover, the antenna or the antenna transmission line shall be disconnected from the antenna terminal device to prevent the introduction of dangerous voltages due to antenna pick-up. When disconnection of the antenna or antenna transmission line is not possible, other suitable precautions shall be taken, for example, earthing, when necessary at several places, to esablish absence of voltage. These earthing connections shall be very short compared with the wave-lenght.  Capacitors which are connected to a circuir isolated frcm its supply shall be discharged and have their terminals permanently short-circuited and the casing earthed during the whole period of the work.  The electrical charge retained by electrical machinery when stopped may, in certain cases, be sufficient to cause a severe shock. This shall be taken into account when making connections to an apparently "dead" machine. Therefore all machinery shall be discharged and earthed using an adequately insulated lead for this purpose. The discharge operation shall be repeated several times.  Before any maintenance work is carried out on automatic or remote controlled equipment, the remote swithching circuits shall be made inoperative. 1.4.1 PROCEDURE FOR DETERMINATION OF THE ABSENCE OF VOLTAGE After the equipment has been isolated according to the standard EN60215, the absence of voltage shall be determined at the work place. This may be done by the use of voltage indicators, measuring instruments, glow discharge lamps for indicating radio-frequency voltage or other suitable means.

A muscular spasm or unconsciousness can make a victim unable to free himself from the electrical power. If power cannot be turned off immediately, very carefully loop a length of dry non-conducting material (such as a rope, insulating material, or clothing) around the victim and pull him free of the power. Carefully avoid touching him or his clothing until free of power. 1.5.1 EMERGENCY RESUSCITATION TECHNIQUE Step 1 Check the victim for unresponsiveness. If there is no response, immediately call for medical assistance, and then return to the person. Step 2 Position the person flat on their back. Kneel by their side and place one hand on the forehead and the other under the chin. Tilt the head back and lift the chin until teeth almost touch. Look and listen for breathing. Step 3 If not breathing normally, pinch the nose and cover the mouth with yours. Give two full breaths. The person's chest will rise if you are giving enough air. Step 4 Put the fingertips of your hand on the Adam's apple, slide them into the groove next to the windpipe. Feel for a pulse. If you can not feel a pulse or are unsure, move on to the next step. DO NOT TOUCH VICTIM OR HIS CLOTHING BEFORE POWER IS DISCONNECTED OR YOU CAN ALSO BECOME A SHOCK VICTIM
