(6) Do not blind the I/O signal cables and high-voltage or power cables. Separate them
as far as possible. If separation is difficult, use shielded cables for the I/O signals and
ground the shield at the leading -in point of the control panel.
(7) Pat attention to Chapter 3 Precautions for I/O Modules.
1. Turn off power before wiring to minimize the risk of electrical shock.
2. Use crimp-style terminals with sheaths as far as possible for wiring to the power supply
module. When it is not possible to use crimp-style terminals with sheaths, cover with
insulating tape so that the conductive parts are not exposed.
3. Apply power of the specified rating.
Applying excess power voltage to the model 2000 can cause explosion or fire.
4. Operation without grounding may cause electrical shock or malfunction. Connect the ground
terminal on the model 2000 to the system ground.
