3.5 Wiring Precautions
WARNING
This product generates high voltage. Be careful of electric shock and electric discharge. To
prevent electric shock, remove rings, watches, and other metallic accessories and jewelry
before wiring.
Before Wiring
• Ground the instrument before connecting the instrument to the target device. The power
cord to use is a three-prong type power cord. Insert the power cord into a grounded three-
prong outlet.
• Be sure to turn off the output before connecting or disconnecting the target device.
• To prevent damage that would occur if the OUTPUT switch is flipped inadvertently during
wiring, check that the minimum and maximum values on the scale are all set to 0 (zero).
• If a large inductive or capacitive load or oscillating circuit is connected to the output
terminals, the output may oscillate and cause high voltage to be applied to the output
terminals. If the output oscillates, turn off the OUTPUT switch immediately.
Wiring
• Make sure to fasten the output terminal screws securely so that lead wires do not come
loose.
• Only use lead wires whose conductive parts are covered for connecting to the high voltage
output terminals (OUTPUT 2 plug-in terminals). Exposed conductive parts can lead to
electric shock.
• Do not use lead wires whose conductive parts are exposed due to tears in the insulation or
broken cables as they may lead to a short circuit or electric shock.
• For connecting to terminals used for high voltage output, only use lead wires that have
safety terminals that cover their conductive parts. Using a terminal with bare conductive
parts (such as a banana plug) can be dangerous if the terminal comes loose.
• Do not use the fork terminal adapter 758921 when outputting from the high voltage output
terminals (OUTPUT 2 plug-in terminals). Due to the structure of the product, it is possible
to touch the metal parts of the fork terminal adapter 758921. Be careful as this constitutes
an electric shock hazard.
• Use the accessories of this product within the rated range of each accessory (see page iv).
When using several accessories together, use them within the specification range of the
accessory with the lowest rating.
Before output (before turning on the output), check that:
• Lead wires are connected to the instrument’s output terminals correctly.
Check that output lead wires that should be connected to low voltage-current output
terminals (OUTPUT 1) are not connected to the high voltage output terminals or large
current output terminals.
• Lead wires are connected to the target device correctly.
Lead wires are not shorted because of wiring errors, broken insulation of lead wires,
unintended contact with conductive parts, and so on.
• The lead wires are fastened firmly to the terminals.
• There no problems with the terminals, such as the presence of foreign substances.
