MXi030U TECHNICAL SERVICE MANUAL

SAFETY NOTICES

This section provides general guidance and information for the operation, maintenance, and service personnel who are familiar with the hazards of working with high-powered electronic circuits. This manual does not detail all of the safety precautions which should be observed when servicing this or any other electronic equipment.

Service by inadequately trained or inexperienced personnel can result in personal injury or death and/or damage to the equipment.

Important: All personnel concerned with the servicing of this equipment should be thoroughly familiar with

standard first aid procedures for the treatment of electrical burns and shock, including cardio-pulmonary resuscitation (CPR).

Use the “buddy” system, with one person performing the actual service and a colleague observing. The observer must be familiar with the work being performed and within sight and sound of the person doing the work. The

observer should not be engaged in any other work or be otherwise distracted; he must be available instantly in

case of accident.

Always have the observer with you when you work on the transmitter.

2.1

BERYLLIUM OXIDE WARNING

Internal thermal management in certain RF devices in this equipment is accomplished through the use of Beryllium Oxide ceramic material. Do not break open any RF power transistors, or otherwise dismantle them. Beryllium Oxide is a hard white ceramic used as insulation for heatsinking of RF power semiconductors. Beryllium

Oxide is a poison. In case of accidental breakage of devices, do not inhale the resulting beryllium dust and

avoid getting beryllium dust in your mouth. Do not let beryllium into your blood stream through cuts or open wounds. Seek immediate medical attention if the dust enters your body in any manner. Avoid cuts by

wearing gloves while picking up the broken pieces. Be careful – do not inhale dust while replacing or emptying vacuum cleaner filter bags and wash your hands thoroughly afterward. Wash your hands thoroughly after replacing RF power devices. Dispose of defective RF power devices only through approved toxic waste facilities. Wear gloves when picking up the pieces. Wash your hands thoroughly after replacing devices. Dispose of defective devices only through approved toxic waste facilities.

When cleaning up after an accidental breakage, remember to wear a respirator mask to avoid inhaling the dust while replacing or emptying vacuum cleaner filter bags and to wash your hands well after servicing the vacuum cleaner. If possible, use a wet vacuum, in which the dust gets trapped in water.

2.2

OTHER TOXIC MATERIALS

The non-metallic coverings of some coaxial cables used in this equipment are flammable and can transmit fire

when ignited. Other wire coverings are not capable of supporting combustion but any non-metallic covering when heated sufficiently can emit dense smoke and acid gases, which can be highly toxic and often corrosive.

Solvents and glues can emit toxic vapors and can be flammable. Read and understand the directions on the containers and ensure that they are used only in well ventilated locations.

2.3

DANGEROUS VOLTAGES

This equipment has been designed to protect operating personnel from accidental contact with dangerous voltages, by means of shields and covers. It is extremely important that any protective covering devices be kept in place at all times.

While all practical safety precautions have been adopted to safeguard personnel from possible injury, both supervisory and operating personnel are urged to ensure that the safety rules detailed below are followed as an established routine at all times. The following four Rules are the standard safety guidelines for working with and around transmitters.

TSM20-378 Rev 0 July 18, 2007 20-378-2 MXi030U Technical Service Manual

MXi030U TECHNICAL SERVICE MANUAL

Rule #1 KILL THE AC POWER BEFORE IT KILLS YOU

Under no circumstances should any person reach within the cabinets for the purpose of servicing or adjusting the equipment without first disconnecting the AC power or without the immediate presence of another person capable of rendering aid. The “buddy” system is encouraged for transmitter work.

Rule #2 DO NOT TAMPER WITH INTERLOCKS OR SAFETY SHIELDS

Under normal circumstances, no safety shield should be removed.

Rule #3 REMOVE PERSONAL JEWELRY WHEN WORKING ON THE EQUIPMENT

The mains AC power to this transmitter can deliver high currents capable of melting metallic tools or personal jewelry, such as watch bands, bracelets, or rings. Accidental short circuits from such metallic objects can cause an explosive shower of molten metal which can result in serious personal injury.

Rule #4 KNOW FIRST AID AND KEEP FIRST AID SUPPLIES AVAILABLE

Illustrated first aid instructions for the treatment of electrical shock and burns and CPR procedures should be displayed in a prominent location adjacent to the equipment. In rendering first aid, the timeliness and effectiveness of the treatment are vitally important to the recovery of the injured person.

Always have a colleague with you when you work on the transmitter and make sure both of you know first aid, including cardio-pulmonary resuscitation (CPR). This is most important.

Without exception, all personnel should thoroughly familiarize themselves with the procedures involved. One person, whose normal duties place him or her at the transmitter site often, should be given complete responsibility and authority to ensure that first aid supplies are kept onsite and maintained. Prominently display a list of emergency phone numbers. This list should include the numbers of the nearest police, ambulance, hospital, doctor, fire department, paramedics, poison control center, public works (roads) department, and the utility (power and phone) companies.

Do not try to work on the transmitter if you are tired or drowsy; you could make a fatal error in judgment.

2.3.1 Switch to Safety

Here are some safety suggestions, based partially on the knowledge of experts familiar with high-powered tubed equipment, and partially on the procedures used at a typical utility company and at a company which makes and tests high voltage devices. A few of these suggestions apply primarily to factory environments and require some modification to be applied in transmitter settings.

Our thanks to the Varian Corporation for sharing its "Electrical Safety Training Program" notes. Our thanks also to Ontario Hydro for its information booklets dealing with high voltage.

Have in place a comprehensive safety program, with defined procedures. Know First Aid and CPR.

observer should not be engaged in any other work or be otherwise distracted; he must be available instantly in case of accident. Always have the observer with you when you work on the transmitter.

Pay attention to emergency communications requirements. This could even include a voice channel on the STL so that constant communication with the studio can be maintained. Headset-equipped phones connected on this voice channel should be installed in locations near hazardous areas or everyone on site should carry fully charged cell phones. When you are administering CPR, you might not be able to leave your patient for the length of time it could take to call paramedics, especially if phone service is poor, or lines are down, and/or you are in a rural area without emergency telephone service (e.g., 911 in North America).

Do not defeat the interlock switches on access doors unless it is absolutely necessary and you know exactly

what you are doing.

Keep the area neat and tidy, free of any interfering conductive material and free of any sharp objects. Remember that reaction to a shock could cause you to strike nearby objects.

TSM20-378 Rev 0 July 18, 2007 20-378-3 MXi030U Technical Service Manual

MXi030U TECHNICAL SERVICE MANUAL

Avoid wearing loose clothing and personal jewelry such as rings, watches, and chains when working near energized circuits. Make a habit of removing all jewelry and storing it in a safe place as soon as you enter the transmitter building.

Before beginning work, shut off all AC to the transmitter power supplies. Tag and lockout the switches.

Your safety routine must ensure that the person placing the tag and locking the switch is the only person who removes it and reactivates the switch. You might want to include the AC to the remote control as well, if there is any possibility that a studio worker could unknowingly activate the transmitter while you are working on it. One way of ensuring that the lockout "placer and remover" are the same person is to issue individual padlocks to each person on the transmitter technical staff.

You might want to include your tower contractor's rigging crew in the list of people who are allowed to use tags and padlocks. As an alternative, Dielectric™ makes a transmission line lockout switch that is intended for riggers to turn off and lock out any RF before climbing over the antenna to replace light bulbs, etc.

Proper grounding is vital. Make ground inspection a part of your maintenance program; someone's life could

depend on it.
