CDM-VW300 Series Dynamic Vibrating-Wire Analyzers
7. As shown in FIGURE 6-12, connect power leads to the CDM-VW300.
Do not turn power on until the system is fully assembled.
Connect dc power to the Power connector on the side of the CDM-
VW300. Voltages from 10 to 32 Vdc may be used. Do not connect ac
power directly to the CDM-VW300. A convenient power source is the
combination of 12V and G terminals on the face of the datalogger.
FIGURE 6-12. Power connection
8. As shown in FIGURE 6-13, connect earth grounds.
Ground lugs are provided for tying the CDM-VW300 and datalogger to
earth ground with large gage wire. 14 AWG wire or larger is
recommended. Reference Section 7.7.5, Earth Ground Connections.
