Preface
Provide Adequate Ventilation
Slots and openings on the TDR6 are provided for ventilation that is needed to ensure reliable
operation. To avoid overheating and ensure that the ventilation slots are not blocked, place the TDR6
on a smooth, hard surface that has at least two inches of clearance around the unit and adequate air
circulation. If the equipment is placed in a closed area, such as a rack, ensure that proper ventilation
is provided and that the internal rack operating temperature does not exceed the maximum rated
temperature at the position of the unit.
Never place the TDR6 on a soft surface that would obstruct the required airflow into the ventilation
slots.
Use Correct Power Source
For units equipped with a North American power cord, the cord has an IEC-compatible female plug
on one end, and a male plug on the other end. This cord is UL and CSA approved up to 125 VAC at
10 A and is ready to use with no user wiring required.
For units equipped with an International power cord, the cord has an IEC-compatible female plug on
one end, and three stripped and tinned bare wires on the other end. This cord is approved up to
250 VAC at 6 A and complies with the international color codes of green/yellow (ground), blue
(neutral), and brown (line).
If these color codes do not correspond to the colored markings on the terminals in the plug, use the
following standards:
■ The green/yellow wire must be connected to the plug terminal marked by the letter E or by the
earth symbol ( ) or color-coded green and yellow.
■ The blue wire must be connected to the plug terminal marked with the letter N or color-coded
black.
■ The brown wire must be connected to the plug terminal marked with the letter L or color-coded
red.
An AC plug must be attached to the International power cord in accordance with government
standards and codes in effect at the installation site. If an unterminated power cord is supplied with
the unit, the appropriate certified termination plug must be installed. The following is a list of the
required certifying agencies for various countries.
Route Power Cords Safely
Route power cords so they are not walked on or pinched. Pay particular attention to cords and
connections at the plugs, receptacles (such as power strips), and the point where they exit from the
TDR6 and attach to other equipment. Do not place any items on or against power cords.
No Stacking
Do not place or stack any objects on top of the TDR6. Other equipment may be placed in a rack or
on a shelf above or below it, but never stacked directly on top of it.
Protect Against Lightning and Power Surges
When the TDR6 is installed, have the professional installer ground the system to protect against
voltage surges and built-up static charges. For information on grounding standards for electrical and
radio equipment, refer to the electrical code in the country of installation.
Protect the TDR6 from lightning and power-line surges during a storm by unplugging it from the
wall outlet and disconnecting the coaxial cable.
