Using Ferrules
If you use ferrules, attach the twisted wires to them.
Observe the application instructions for your ferrules for the wire stripping length when attaching fer-
rules.
Always use plated one-pin ferrules. Do not use unplated ferrules or two-pin ferrules.
The applicable ferrules, wires, and crimping tools are listed in the following table.

Grounding
The type of ground terminal on the Power Supply Unit is a functional ground terminal.
A functional ground terminal takes protective measures for device and system functions, including pre-
vention of noises from external sources, and prevention of noises from devices or equipment that may
have harmful ef
fects on other devices or equipment.
• Ground to 100 Ω or less, and when possible use a separate ground from those of other devices.
• If using an independent ground is not possible, then use a common ground. Connect to the ground
pole of the other device.
• Never use a common ground particularly with a motor, inverter, or other type of high-power equip-
ment. Use an independent ground so that the devices do not affect each other.
• To reduce the risk of receiving an electric shock, do not connect devices to ground poles to which
multiple devices are connected.
• Use a ground pole as close to the Power Supply Unit as possible and keep the ground line as short
as possible.
