3.3 Safety Symbols
Assemblies within the transmitter system that contain high voltage conditions have safety
symbols attached to them.
HIGH VOLTAGE
This symbol identifies the presence of high voltage that can cause injury or death.
3.4 Electrical Shock and the Human Body
Electrical shock or electrocution occurs when the body becomes part of an energized electrical
path and this electrical energy passes through the body.
The body subjected to a difference of potential, or stored electrical charge causing current to
flow through the body, will be shocked or electrocuted. Effects of electrical shock may include
severe burns to the skin and/or internal organs and respiratory or cardiac arrest. Any electrical
current that flows through the central nervous system of the human body has the potential to
cause serious injury or death.
Severity of electrical shock depends upon the source and duration of exposure. Use the
following information in conjunction with a vigilant and on-going safety program. This information
is in general terms and does not include unknown variables that may increase susceptibility to
electrical shock. Always exercise Awareness and Caution.
Direct Current (DC): Low voltage (up to 72 VDC) usually does not present a hazard to human
life, but a severe burn is possible under some conditions. Medium and high voltage (greater
than 72 VDC) can cause severe shocks, burns, and even death.
Alternating Current (AC): At commercial frequencies (50-60 Hz) and intermediate voltages (72
to 600 VAC), lethal current can flow through the body. Even low AC voltages (24 VAC or less)
under certain circumstances can be dangerous and lethal. The danger of shock is less at high
frequencies, but radio-frequency (RF) burns are possible.
Body Resistance: The resistance of the body and the amount of insulation between the body
and electrical earth-ground determine the amount of electrical current that passes through the
body. The skin presents the greatest resistance of the human body to impede current flow.
Please note that skin resistance decreases with increased voltage.
Time of Contact: The length of time the body remains in contact with electrical current
determines the severity of possible injury. Burns break down the skin and thus lowers the body’s
ability to resist electrical current. The more extensive the burn, the less resistance the skin
provides. As current flow increases, so does the severity of the shock. The duration of contact is
critical. Current flowing through the body causes loss of muscle control, chest contractions
(breathing is impaired) and ventricular fibrillation of the heart. During fibrillation, the heart cannot
pump sufficient quantities of blood.
Magnitude: The magnitude of the electrical current determines the extent of muscle-control
loss, effects on the heart, and severity of burns.

Safety - 5 -
®
Affinity LBD-200C-N1 Transmitter
Product Manual
Path: The path of the electrical current through the body is critical. When current passes from
hand to hand, or hand to foot, the brain, heart, lungs, and spinal cord, which become part of the
electrical path, are affected.
Age and Condition of Victim: The age and physical condition of the victim affects the severity
of electrical shock. Elderly victims, young children, or those with existing medical conditions, are
more susceptible to injury caused by electrical shock.
3.5 Emergency Procedures for Electrical Shock
Anyone engaged in electrical or electronic work should be aware of the proper safeguards and
emergency procedures related to hazardous electrical conditions. An understanding and
knowledgebase regarding electrical hazards will reduce the risks and dangers of electrocution.
Obtaining safety related training courses such as First Aid and CPR, and applying them during
emergencies, might greatly reduce the effects of electrically induced injuries.
Promptly report to the appropriate personnel any electrical “popping” or sparking, and any
noticeable defects or hazardous conditions that can cause injury, property damage, or
interference to the electrical equipment.
Immediately report any electric shock received to the appropriate supervisor or safety
personnel.
In the event that an individual comes into contact with a live electrical circuit:
x Cut off the power. Learn how to remove power anywhere within the work area.
x Free a victim from a live circuit. If a person is “frozen” to a live electrical contact,
turn off the power if possible. If you cannot turn off power, use wooden boards,
poles, sticks, a belt, dry rope, articles of clothing or some other nonconductive
material of sufficient strength to pull the affected person from electrical contact.
x Contact emergency personnel. Immediately contact emergency medical
personnel. Only qualified and trained personnel should perform First Aid
procedures.
WARNING
Under no circumstances touch a victim
exposed to a live circuit. Doing so will place
you in the live circuit, and may result in
injury or death due to electrocution.

3.6 Transmitter Electrical Hazards
WARNING
Use appropriate practices when working
near high voltage. The removal of panels
identified with warning symbols can
expose the mains voltages. These
voltages can cause injury or death.
Transmitter Electrical Hazards Warning
The transmitter uses lethal voltages that can cause injury or death. The transmitter assemblies
fully enclose these voltages to prevent accidental contact.
Thales recommends these safe-working practices:
x Operate and maintain the transmitter according to the instruction manuals.
x Do not allow personnel to work alone on the transmitter.
x Permit only skilled personnel to operate the transmitter. See IEC 60215.
x Ensure personnel know the location of circuit breakers and mains disconnect
switches.
x Ensure the transmitter is OFF, disconnected from the AC mains voltage, and
secured via a lock-out/tag-out process before working in any areas identified with
warning symbols.
x Ensure all personnel have training in First Aid and CPR procedures.

independent single drive transmit chains fed by a common exciter with embedded time delays
on each output. The exciter time delay function is defined in the DVB-H standard, EN 300744.
The delay must be within the guard interval defined in the network, and should add a few
microseconds of delay in relation to the other transmitter in the site. The timing information can
be sent to the transmitter via the Megaframe Information Protocol (MIP) or can be adjusted
locally in the modulator.
4.3 Affinity® Family Construction
The Affinity®family of low power solid-state DTV transmitters is designed to provide maximum
flexibility for site layout and installation. All of the transmitter chassis are designed to fit in EIA
standard 19” wide equipment cabinets. Outdoor installations are equipped with high quality front
and rear access enclosures. These enclosures maintain security and protection against external
elements. Transmitter systems are available in several configurations based on output power,
redundancy options, and site system requirements.
Single channel, non-redundant transmitter configurations (SD) are sized as follows:
For 50 to 125 watt average output power levels, the upconverter and amplifier are self-
contained in a single 6 rack unit (RU) chassis. The N+1 capable power supply is housed
in a 3RU chassis, and the Thales DVB- T/H RF exciter is contained in a 2RU chassis.
This 11RU transmitter is the most compact Thales Affinity system.

Affinity LBD-200C-N1 Transmitter
Product Manual
The transmitter uses self-contained ambient forced air-cooling (front to back airflow). All fans
are internal to the chassis. Refer to the Cabinet Air Conditioning section of this manual for
additional details of the LBD-200C-N1 transmitter cooling and environmental control systems.
The transmitter system including all ancillary equipment is housed in a Nema 3R rated
enclosure with approximate dimensions: 74” H x 44” W x 44” D. This self-contained unit features
eyelets for lifting the entire assembly during installation. The base has mounting provisions for
mechanical and electrical attachments to building structures. Equipment access is achieved
through front and rear opening doors fitted with locks and intrusion alarms with remote
signaling. Internal enclosure lights illuminate when any door is opened during maintenance. A
smoke/fire detector with remote signaling is utilized to provide the earliest warning of
catastrophic failure caused by a natural occurrence or other means.
Located inside the enclosure is an EIA standard 19” rail structure system used for rack
mounting each sub system contained in the Affinity® configuration.
The AC distribution system is comprised of: 120/230VAC surge suppression with alarms, two
230VAC outlets, and two 120VAC outlets with separate circuit protection. Four 230VAC utility
outlets are provided along with four UPS protected outlets located along the rear corner of the
enclosure. These outlets are intended to connect transmitter ancillary equipment. An external
disconnect box allows connection of a portable generator. An AC hour-meter will record the
operational hours of the equipment.
A UPS is employed to keep critical subsystems running in instances of temporary AC power
loss. The 230VAC UPS output is capable of 700VA/490W. Storage for the UPS is via two
24VDC extended battery modules capable of providing an output of approximately 210 Watts for
400 Minutes (6.9 Hrs). This power is intentionally distributed to the site management system,
satellite receiver, and DVB-T/H RF exciter to enable status communications from the site, back
to the operations center, to continue while normal operating site power is absent. Having the
exciter and satellite receiver powered up also minimizes transmitter restart times once normal
site power has been restored.
