Phaser 7500 Printer Service Manual xxiii
Power Safety Precautions
Power Source
For 115 VAC printers, do not apply more than 127 volts RMS between the supply
conductors or between either supply conductor and ground. For 230 VAC printers,
do not apply more than 254 volts RMS between the supply conductors or between
either supply conductor and ground. Use only the specified power cord and
connector. 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. A protective ground connection by way of the
grounding conductor in the power cord is essential for safe operation.
Disconnecting Power
Turning the power Off using the power switch does not completely de-energize
the printer. You must also disconnect the power cord from the printer’s
Alternating Current (AC). Disconnect the power cord by pulling the plug from
the outlet.
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 product,
• if the printer is exposed to any excess moisture,
• if the printer is dropped or damaged,
• if you suspect that the product needs servicing or repair,
• whenever you clean the product.
