TRACER 6000 Series Integrated System Manual Section 3 Engineering Guidelines612806420L1-1F Copyright © 2005 ADTRAN, Inc. 35DC Power Connection (Plug-In Terminal Block)The TRACER 64x0 can operate from a supply between 21 and 60 VDC, with either polarity referenced toground, and consumes less than 25 W. Power supplies should be able to provide up to 25 W at the selectedvoltage. Current required (in amps) is determined by dividing the power consumed (in watts) by the appliedvoltage (in volts). For example, at 48 V, TRACER 64x0 would draw approximately 0.52 A(25 W/48 V). Table 8 shows the DC power connection pinout.FuseThe fuse holder, accessible from the rear panel of the TRACER 64x0, accepts a generic 2 A, 250 V, 2-inchslow-blo fuse.Alarm Contacts (Plug-In Terminal Block)An RF link down condition is indicated with both normally open (NO) and normally closed (NC) alarmcontacts on the rear panel of the TRACER 64x0 system. In normal operation, the NC contact is electricallyconnected to the common contact (COM) and the NO contact is isolated. When the RF link drops, the NCcontact becomes isolated and the NO is electrically connected to COM. This allows RF down conditions tobe reported to external alarm monitoring systems. Table 9 provides the alarm contact pinout.Antenna Interface (N-Type Connector)The ANTENNA interface (N-type connector) connects to the customer-supplied antenna using standardantenna feedline cable. When determining the cable specifications for your application, refer to Section 2,Microwave Path Engineering Basics (System Losses (L) on page 21) for a discussion on cable length andApplying power to the radio without a 50Ω load attached to the antenna interface candamage the system. Verify the 50Ω load is attached before powering the radio.When using a power source that has the positive terminal or the negative terminalconnected to earth ground, the grounded terminal must be attached to the TRACER 64x0power input that is identified with the ground symbol. Otherwise, equipment damage willoccur. When using a power source that has neither terminal connected with earth ground(floating), either terminal may be connected to the TRACER 64x0 power input identifiedwith the ground symbol.Table 8.
