Equipment Location
The TC3006 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 TC3006 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
beutilized. When this feature is utilized,both "A"and "B"share theload. If onepower sourcefails, theother
willassume thefull load. Polarity isindicated oneachconnector block.Alternate power sourcesare 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). Normallyin theOPEN position,theloss ofeither opticsignal
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.
