Tighten all screws. Do not turn the screws too tight. - GROUNDING NOTE - Always follow local safety precautions and standard operating proce- dures for grounding the equipment when installing, upgrading, repairing or maintaining equipment. Any instructions or information contained herein is subordinate to local codes, operating procedures or practices. - CAUTION - Do not attempt to operate units in the assembly without an approved safety ground connected to the Frame Ground lug. - NOTE - GND Lug The -48Vdc input return terminal is an isolated DC return Figure 2.

One is for the connection of main power, the other is for 3.5 Alarm Connections connection of a back-up power source. This type of connection allows for fail-safe operation in the event a loss of main power An Alarm terminal, shown in Figure 2 and Figure 3, is provided occurs. Refer to Figure 3 while connecting the power wiring. for an alarm indication from the units installed in the mounting. The alarm terminal provides both a Normally Open (NO) and a Normally Closed (NC) connection. Alarm contacts close/open in the event the fuse on an NIU opens. An #18 to #12 AWG size wire is recommended for alarm connections. 3.6 Fuse Recommendations To protect the modules mounted in the shelf, a fuse should be installed in the power circuit of the shelf. A 1/2 Amp fuse is rec- ommended for the main and the back-up power sources. 3.7 DS3 Connections DS3 connections are made to each unit using the coaxial cable connectors at the rear of the mounting. The 200-03FA Mounting comes with a removable, protective plate to keep the network Figure 3. Terminal Block Power Connections connections from being accidentally removed or changed. Refer to Figure 5 and Figure 6. 1008I1RB 4 030-101604 Rev. B Section DBM-A20-003-201 � Before inserting a module, set any option switch(es) to the de- sired position(s) and loosen the appropriate thumbscrew so that the module can be inserted. Align the module with the mounting or assembly card guides above and below the unit and insert as far as it will go into the connector. Tighten the thumbscrew to se- cure it. - CAUTION - Be sure to tighten the thumbscrews so that cards do not accidentally get removed during test procedures. - CAUTION - Use care when installing and removing modules - do not force a module into place. If a module resists insertion, remove it and check for obstructions in or near the module’s or shelf’s connectors and mounting slots. The module may then be carefully aligned and gently re-inserted. - NOTE - Set any/all manual option switches prior to installing the unit. 4.
