Electrostatic Discharge Precautions
WARNING
The IQ-203 Control Unit was designed to be a test instrument that
should not be opened by users. EXFO is not responsible for any
personal injury incurred while attempting internal service of the
IQ-203 Control Unit or IQ-206 Expansion Unit.
➤ Unit covers cannot be removed during operation.
➤ Before powering on the unit, all grounding terminals, extension cords,
and devices connected to it should be connected to a protective
ground via a ground socket. Any interruption of the protective ground
will cause a potential shock hazard and possible personal injury.
➤ Whenever the ground protection is impaired, the unit must not be used
and be secured against any accidental or unintended operation.
➤ Only fuses with the required rated current and specified type (normal
blow, time delay, etc.) may be used for replacement. Do not use
repaired fuses or short-circuited fuse holders.
➤ Any adjustments, maintenance, and repair of opened units under
voltage should be carried out only by skilled personnel aware of the
hazard involved. Do not replace any components while power cable is
connected. EXFO is not responsible for any personal injury incurred
while manipulating the unit.
➤ Operation of any electrical instrument around flammable gases or
fumes constitutes a major safety hazard.
➤ Capacitors inside the unit may be charged even if the unit has been
disconnected from its electrical supply.
