Grounding - Omron CK3M Seres Hardware User Manual

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 effects 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.
