Introduction
Thank you for purchasing the HIOKI Model PW9000/PW9001 Wiring Adapter.
To obtain maximum performance from the device, please read this manual
first, and keep it handy for future reference.
The Wiring Adapter are specially designed to facilitate connections
to three-phase 3- and 4-wire systems using the PQ3198 Power Quality Ana-
lyzer. It can also be used with the PW3390 Power Analyzer.
For more information about safety precautions and maintenance service, refer
to the instruction manual for the device to which you plan to connect the wiring
adapter.
For connection to the PW3390, see the PW3390 Instruction Manual.

Before Use
Indicates cautions and hazards. When the symbol is printed on
the instrument, refer to a corresponding topic in the Instruction
Manual.
Indicates an imminently hazardous situation that will result in
death of or serious injury to the operator.
Indicates a potentially hazardous situation that may result in
minor or moderate injury to the operator or damage to the device
or malfunction.
To prevent an electric shock accident, confirm that the white or red
portion (insulation layer) inside the cable is not exposed. If a color
inside the cable is exposed, do not use the cable.
Connecting a Wiring Adapter
• Do not exceed the maximum input voltage during measure-
ment. Doing so may damage the adapter or cause injury.
• The maximum terminal-to-ground rated voltage is 1,000 V
(Cat III) or 600 V (Cat IV). Do not exceed these voltages rela-
tive to ground during measurement. Doing so may damage
the adapter or cause injury.
• The maximum input voltage and maximum terminal-to-
ground rated voltage depend on the connected device.
PQ3198
PW9000
Connect all 6 output pins on the
wiring adapter to the voltage input
terminals on the device to which it
is being connected. Insert plugs all
the way in.
