3.0 Initial system setup
Note: All cables should be installed and connections should be completed before switching the
power/circuit breaker switch to "ON."
3.1 AC line power
The power amplifier is wired at the factory for either 120 VAC or 230 VAC.
This AC voltage power wiring is not changeable by the user. The AC power
source should be capable of providing a minimum of 20amps at 120 VAC or
13 amps at 230VAC. A power cord terminating in an IEC320 plug should be
connected from the power amplifier to the AC power line socket.
3.2 Signal input
A laboratory grade low-noise oscillator should be used as a signal source. Use a coaxial cable to
provide the input signal to the BNC connector on the rear panel of the power amplifier. To avoid
hum and noise pickup, avoid running the signal cable parallel to power line cords. Any cabling
near power line cords should be crossed at right angles. The driving signal amplitude is
controlled by the signal generator amplitude control. It is recommended that the signal generating
amplitude control be preset, considering the signal generator’s capability, to eliminate the
possibility of overdriving the power amplifier.
3.3 The power amplifier, matching network, and shaker cables
Electromagnetic shakers do not require a matching network and are connected directly to the
power amplifier with the indicated cable type. Piezoelectric shakers require a matching network
between the power amplifier and shaker, therefore two cables will be necessary to complete the
connections. Table 1 describes the cable types required for completing all shaker system
connections.
