Safety summary
1. Make sure that the power amplifier is properly grounded to a good earth ground.
2. Make sure that any piezoelectric shaker being driven is properly grounded to a good earth
ground.
3. Disconnect the power cord at its source before connecting or removing power amplifier
cables.
4. To reduce the risk of electric shock, do not remove the power amplifier cover. No user-
serviceable parts are inside. Refer all servicing issues to Meggitt Sensing Systems.
5. Do not attempt to operate a power amplifier without the protective covers secured.
6. All cables must be connected between the power amplifier, matching network and shaker
before electrical power is connected. Inspect for frayed or cut cables prior to operation.
7. Hearing protection devices are highly recommended in the vicinity of a piezoelectric shaker
whenever the shaker is being driven at high output levels.
8. Do not expose this equipment to rain or moisture.
9. Lethal high voltage may be present at the power amplifier output connector.
10. When using the D125L piezoelectric shaker, it requires pressurization (minimum 1800 PSI)
from a source of dry, inert gas. The D125L shaker must be electrically connected to the
matching network and power amplifier, or the shaker terminals should be shorted together,
prior to pressurization or de-pressurization. Pressure must be applied or released slowly (1
minute) to prevent excessive voltages at the shaker connecting terminals. Use extreme
caution when handling pressurized cylinders.
11. Use common sense and avoid haste!
