4.3Testing Static Trip III on Desktop

If you are testing a Static Trip III trip unit on a desktop, follow these steps to connect the trip unit to the converter for

15 VDC power, while referring to Figure 4.3:

1.Plug the connector of the two-conductor cable into the 15 VDC output port.

2.Making sure to observe the polarity of the cable, connect the other end to terminals 2 and 3 on the 10-pin connector supplied with the Static Trip III.

3.Connect an RS-485 cable between the 10-pin connector and the converter. (You may need to prepare a length of RS-485 cable as described in section 3.1 above.) Plug the cable’s three-terminal connector into an RS-485 port on the front of the converter. Connect the black wire from the other end of the cable to Data(+) (terminal 4) on the 10-pin connector,

and connect the white wire to Data(-) (terminal 5) on the 10-pin connector.

4.Plug the 10-pin connector into the 10-pin connector port located on the back panel of the Static Trip III.

5.Plug one end of the converter’s power cord into the 120 VAC connection on the converter, and plug the other end into any 120 VAC grounded power source.

6.Turn the power switch on.

7.Using testing software supplied by Siemens, verify that the attached trip unit communicates properly.

4.4Testing SAMMS on Desktop

If you are testing a SAMMS device on a desktop, follow these steps to connect the device to the converter, while referring to Figure 4.4 on the next page and to the SAMMS- LV User’s Manual (Manual No. MC-3298) or SAMMS-MV User’s Manual (Manual No. MVC-9108):

1.Prepare 2 two-conductor cables by connecting them to one two-terminal connector, as described at the beginning of this section and illustrated in Figure 4.4.

2.Plug the connector of the two-conductor cables into the 15 VDC output port.

3.Making sure to observe the polarity, connect the other end of one of the two-conductor cables to terminals

5 and 6 of the terminal block on top of the SAMMS.

4.Again making sure to observe polarity, connect the other end of the second two-conductor cable to the PWR (+) and PWR (-) terminals on the five-terminal connector supplied with the SAMMS Communication Module CM-1.

5.Connect an RS-485 cable between the SAMMS five- terminal connector and the converter. (You may need to prepare a length of RS-485 cable; see section 3.1.)

6.Plug the cable’s three-terminal connector into an RS-485 port on the front of the converter. Connect the black wire from the other end of the cable to the (+) terminal on the five-terminal connector, and connect the white wire to the (-) terminal on the connector.

7.Plug the five-terminal connector into the SAMMS Communication Module CM-1.

8.Connect the CM-1 to the SAMMS device using the supplied ribbon cable as illustrated in Figures 12 and 13.

9.Plug one end of the converter’s power cord into the 120 VAC connection on the converter, and plug the other end into any 120 VAC grounded power source.

10.Turn the power switch on.

11.Using testing software supplied by Siemens, verify that the attached SAMMS device communicates properly.
