Page 10: Initial System Setup
Wilcoxon Sensing Technologies power amplifiers are purchased and shipped separately from vibration generator products. Refer to the operating guide supplied with the power amplifier for connection instructions. If using a power amplifier other than one supplied by Wilcoxon, follow that manufacturer’s recommended procedure for installation and operation. -
Page 11: Connect The Matching Network
Do not exceed the maximum input voltage to the piezoelectric shaker if another powering system is used. 3.5.5 The following table indicates the cable types and connections for the Wilcoxon Sensing Technologies power amplifiers, matching networks, and piezoelectric shakers. This table should be consulted for guidance as to cable and equipment connection. -
