Power Safety Precautions
Power Source
For 110 VAC units, do not apply more than 140 volts RMS between the supply conductors or between either supply
conductor and ground. Use only the specified power cord and connector. For 220 VAC units, do not apply more
than 264 volts RMS between the supply conductors or between either supply conductor and ground.
Use only the specified power cord. This manual assumes that the reader is a qualified service technician.
Plug the three-wire power cord (with grounding prong) into a grounded AC outlet only. If necessary, contact a licensed
electrician to install a properly grounded outlet. If the product loses its ground connection, contact with conductive
parts may cause an electrical shock.
Disconnecting Power
Turning the power off using the On/Off switch does not completely de-engergize the equipment. You must also disconnect
the unit power cord from the AC outlet. Position the power cord so that it is easily accessible during servicing
so that you may power down the unit during an emergency.
Disconnect the power plug by pulling the plug, not the cord.
Disconnect the power cord in the following cases:
■ if the power cord or plug is frayed or otherwise damaged,
■ if any liquid or foreign material is spilled into the case,
■ if the equipment is exposed to any excess moisture,
■ if the equipment is dropped or damaged,
■ if you suspect that the product needs servicing or repair,
■ whenever you clean the product.
