Powerline disturbances Reliable operation of your printer depends on the availability of relatively noise-free AC power. ● In order to ensure optimum performance and reliability, your printer should be protected from variations in line voltage. Lightning, line faults or the switching of lighting or machinery can generate line transients that far exceed the peak value of the applied voltage. If not reduced, these microsecond pulses can disrupt system operation and damage the printer. ● It is recommended to include overvoltage (OVP) and transient protection in the power supply to the printer. ● All electrical noise-generating equipment, such as fans, fluorescent lighting and air-conditioning systems, should be kept separate from the power source used for your printer. Grounding The printer must be connected to a good-quality ground line in order to avoid electrical risk. Please note your obligation to comply with the Electrical Code requirements of the local jurisdiction of the country where the equipment is installed. The following grounding tasks must be fulfilled to meet the site preparation requirements: ● Grounding wires must be insulated and at least equal in size to the phase conductors. ● Ground impedance must be less than 0.5 Ω. 8 Chapter 2 Site preparation requirements ENWW
