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 that comes with the instrument 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 capacitive load or oscillating circuit is connected to the voltage terminals, the
output may oscillate and cause high voltage to appear at the voltage output terminals. If the
output oscillates, turn it off immediately.
• If a large inductive load or oscillating circuit is connected to the current terminals, the output
may oscillate and cause high voltage to appear at the current output terminals. If the output
oscillates, turn it off immediately.
Wiring
• Make sure to fasten the output terminal screws securely so that cables do not come loose.
• Only use cables whose conductive parts are covered for connecting to the voltage output
terminals. Exposed conductive parts can lead to electric shock.
• Do not use cables 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 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 voltage output
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:
• Cables are connected to the instrument’s output terminals correctly.
• Cables are connected to the target device correctly.
Cables are not shorted because of wiring errors, broken insulation of lead wires,
unintended contact with conductive parts, and so on.
• The cables are fastened firmly to the terminals.
• There no problems with the terminals, such as the presence of foreign substances.
