Providing Power to a CO Power Unit

After the CO Power Unit installation procedure is completed, you must provide power to the unit. There are a number of powering options available depending upon your configuration.

NOTE

The option strap settings are factory set for the Basic mode of operation.

To provide power to the CO Power Unit operating in Basic mode:

"Procedure

1.Use one connector housing (AMP part

number 1-480698-0) and two crimp-type contacts

(AMP part number 350550-1) to attach the connector to your ± 48 Vdc power input cable.

Note that you need a hand crimping tool (AMP part number 90296-2 or equivalent) to build the connector.

(The contacts are crimp type and are intended for use with 20 AWG through 14 AWG wire with a maximum insulation diameter of .130 inches. For additional information, see Appendix A of this guide.)

2.Provide external fusing, if desired. (The fuse shown in Figure 2-5is optional as per your requirements.) The optional fuse should have a rating of 6 amperes, 250 volts, and be a fast-acting type. Use a fuse similar to Littlefuse #312006.

3.Plug the input power cable to either the ±48VDC A connector or the ±48VDC B connector. See Figure 2-5. (The option strap settings for this power option are listed in Table 2-2.)
