Installation of the HP 70206A System Graphics Display
Installation of the display into an HP 70000 Modular Measurement System requires the
foll owing steps:
1. Setting the line voltage selector.
2. Addressing the display.
3. Connecting the display to a mainframe.
Line Voltage Selector
Set the line-voltage selector to the setting that corresponds to the power source used. The
voltage selector switch is located on the rear panel, just above the ac power cord receptacle
housing. Refer to Figure 2-4 for an illustration of the line-voltage selector.

Installation
Before turning this instrument on, be sure it is grounded through the protective
conductor of the ac power cable to a socket outlet provided with protective
earth contact. Any interruption of the protective (grounding) conductor inside
or outside the instrument, or disconnection of the protective earth terminal, can
result in personal injury.
Before turning this instrument on, make sure the line voltage selector is set to
the voltage of the ac power source:
= 115 V position for 90 to 132 V ac line input voltages.
= 230 V position for 198 to 264 V ac line input voltages.
Failure to set the ac power input to the correct voltage could cause one of two
things to happen when power is applied:
m If the switch is set to 115 V and the instrument is connected to 230 V, the
fuse will blow.
m If the switch is set to 230 V and the instrument is connected to 115 V, the
instrument will not turn on and the
VOLT/TEMP fault indicator will light.
