Power Requirements
HP DesignJet 230 and 330 and HP DesignJet 250C and 350C plotters have self adjusting power supplies and do not require a voltage selector or switch settings prior to use. The table below lists the power requirements for the plotters. Power Requirements
Source Voltage Requirements: Voltage 100 V ac 120 V ac 220 V ac 240 V ac Normal Operating Range: Frequency: Consumption: 90 to 264 V ac 47-63 Hz 140 watts maximum Max current (rms) 1.40 A 1.17 A 0.64 A 0.60 A
WARNING
The ac power outlet (mains) must have a protective earth (ground) terminal. Serious shock hazard leading to death or injury may result if the plotter is not properly grounded.
Choosing an Interface Cable
(Instructions ' User's Guide, chapter 1, w Connect the plotter to your computer.)
Serial (RS 232 C) Interface A short cable (less than 15 meters or 50 feet) is recommended
for the RS 232 C interface. A longer cable is permissible, provided the load capacitance does not exceed 2500 picofarads.
Parallel (Bi Tronics/Centronics) Interface Use a short cable (less than 2 meters or 6.6 feet)
for the parallel interface.
(Interface descriptions ' Service Manual, chapter 5, w Input/Output Interfaces.)
