Unpacking the Unit

Before unpacking any equipment, inspect all shipping containers for evidence of external damage caused

during transportation. The equipment should also be inspected for damage after it is removed from the

container(s). Claims concerning shipping damage should be made directly to the pertinent shipping agencies.

Any discrepancies should be reported immediately to the Customer Service Department at TC Communi-

cations, Inc.

Equipment Location

The TC3007 should be located in an area that provides adequate light, work space, and ventilation. Avoid

locating it next to any equipment that may produce electrical interference or strong magnetic fields, such as

elevator shafts or heavy duty power supplies. As with any electronic equipment, keep the unit from excessive

moisture, heat, vibration, and freezing temperatures.

Power Supply

Standard input power to the TC3007 is 12VDC @600mA. There are two pairs of terminal block connectors

on the rear panel (labeled "PWR A" and "PWR B"). Only one pair is required to power the unit. Polarity

is indicated on each connector block. If both pairs are connected, the built-in power redundancy feature will

be utilized. When this feature is utilized, both "A" and "B" share the load. If one power source fails, the other

will assume the full load. Polarity is indicated on each connector block. Alternate power sources are available

as an option (see Chapter 4 - Specifications).

Dry Contact Relay Alarm

A terminal block connector on the rear panel (labeled

"ALARM") provides for the dry contact relay alarm (see Figure

2). Normally in the OPEN position, the loss of either optic signal

will trigger an alarm condition and force the switch to the

CLOSED position. This relay can be used in conjunction with

an external device to monitor the condition of the fiber optic

links. Note: If SW4 (DISALM) on the front panel is in the

Down position, the audio buzzer will not sound and the dry

contact relay will not activate.
