Safety Precautions

Carefully read and follow all safety, use, and operating instructions before operating the unit. Heed all warnings
and cautions contained in this guide. Retain these instructions for future reference.

Follow Startup Procedure

Do not plug in the unit until you have connected the system and read the chapter on installation.

Provide a Safe Location

Place the unit in a rack or on a stable surface of sufficient size and strength, where it will not be jarred, hit, or
pushed off its surface. Ensure that all cables and cords are out of the way and will not be tripped over, as this
could cause personal injury or serious damage to the equipment.

Avoid Water and Moisture

If the equipment is exposed to any liquid, contact Tiernan, a Radyne Company , as serious damage could occur
to the unit or its components.

Avoid Heat, Humidity, and Dust

To avoid internal damage, the unit should be placed away from all heat sources, including radiators, heater ducts,
and so on, out of direct sunlight and away from high humidity, excessive dust, or mechanical vibrations that can
cause damage to internal parts.

Provide Adequate Ventilation

Slots and openings on the unit 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 unit 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 unit 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
