Regulatory Information
USA Electromagnetic Interference Regulatory Statement
Electronic test and measurement equipment is exempt from FCC part 15, subpart B
compliance in the United States of America. However, EXFO Inc. makes reasonable efforts
to ensure compliance to the applicable standards.
The limits set by these standards are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the user documentation, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at
his own expense.
Modifications not expressly approved by the manufacturer could void the user’s authority to
operate the equipment.

Electrical Safety Information
Electrical Safety Information
This unit uses an international safety standard three-wire power cable. This cable serves as
a ground when connected to an appropriate AC power outlet.
The color coding used in the electric cable depends on the cable. New plugs should meet
the local safety requirements and include:
³adequate load-carrying capacity
³ground connection
³cable clamp
WARNING
³If you need to ensure that the unit is completely turned off, disconnect the
power cable.
³Use only the certified power cord that is suitably rated for the country where
the unit is used.
³Replacing detachable MAINS supply cords by inadequately RATED cords may
result in overheating of the cord and create a risk of fire.
WARNING
³Use this unit indoors only.
³Do not remove unit covers during operation.
³Operation of any electrical instrument around flammable gases or fumes
constitutes a major safety hazard.
³To avoid electrical shock, do not operate the unit if any part of the outer
surface (covers, panels, etc.) is damaged.
³Only authorized personnel should carry out adjustments, maintenance or
repair of opened units under voltage. A person qualified in first aid must
also be present. Do not replace any components while the power cable is
connected.
³Use only fuses with the required rated current and specified type . Do not
use repaired fuses or short-circuited fuse holders. For more information, see
the section about replacing the fuses in this user documentation.
³Unless otherwise specified, all interfaces are intended for connection to

3 Getting Started with Your
T200S/T500S
This section explains how to properly install and connect your T200S/T500S.
Unpacking and Installing the T200S/T500S
The T200S/T500S is designed for indoor use only, and is not dedicated to wet locations. It
must be operated under proper environment conditions, as explained in the following
procedure.
This section explains how to install the T200S/T500S as a bench top instrument.
To install the T200S/T500S into a rack, EXFO provides a specific rack mount shelf (for more
details, contact your sales representative). The procedure to install the T200S/T500S into a
19" rack is available in the manual delivered with the rack mount kit.
To unpack and install the T200S/T500S:
1. Open the package with care and remove the protective foam.
2. Pull out the T200S/T500S vertically from its packaging and keep it horizontal.
3. Set the T200S/T500S on a flat stable surface free of excessive vibration.
4. Allow the flow of air to circulate freely at the front and rear of the T200S/T500S and
remove any equipment or paper that could block the air flow. Ventilation holes are
located on the front and rear sides of the T200S/T500S.
5. On the rear panel (see Rear panel on page 3), make sure the power switch is set to O.
6. To tilt the T200S/T500S upward (bench-top use only), deploy the two retractable legs
located below it, as illustrated in the following figure.
CAUTION
³Make sure the location where the T200S/T500S will be installed meets the
environmental characteristics listed in Electrical Safety Information on page 10.
³Do not install the T200S/T500S near any source of heat or cold.
³To ensure proper ventilation and cooling, make sure there is sufficient clearance
at the front and at the rear of the T200S/T500S in the place where it will be
installed.
IMPORTANT
When unpacking, handle the device with care and do not damage the original
shipping container in case the T200S/T500S needs to be returned to EXFO.

Getting Started with Your T200S/T500S
14 T200S/T500S
Connecting the T200S/T500S to a Power Source
Connecting the T200S/T500S to a Power Source
The T200S/T500S has a chassis connected to ground via the power supply cable. A
protective ground connection by way of the grounding conductor in the power cable is
essential for safe operation.
To connect the T200S/T500S to a wall socket:
1. Make sure the power switch is set to O.
2. On the rear panel, connect the power supply cable provided with the instrument to the
mains socket located on the rear panel of the T200S/T500S.
3. Plug the other end of the power supply cable to the proper voltage wall socket outlet (to
know the voltage requirement, see Electrical Safety Information on page 10).
4. On the rear panel, set the power switch to I.
WARNING
³Make sure the wall socket on which the T200S/T500S will be plugged is
protected by a 16 A max circuit breaker.
³Make sure the T200S/T500S power source does not apply more than 265 Volts
RMS between the supply conductors and the ground.
³To avoid the possibility of injury, make sure the socket outlet in which the
power supply cable will be plugged is equipped with a protective ground
contact, and that the electrical installation fulfills the local safety requirements.
