WARNING
Turn off power before connecting or disconnecting cables. The CSD-709 is not
equipped with a power switch. When you conduct work with the CSD-709 turned on,
electric shock or equipment damage may result.
Before turning on power, check to confirm that the power supply voltage indicated
on the CSD-709 and in the specifications agrees with the voltage actually supplied.
Using an unconfirmed power supply may result in electric shock or equipment
damage.
CAUTION
The connector board on the rear panel of the CSD-709 is a resin component. Do not
drop it or subject it to strong impact.
Always use shielded cables, except for power cables. Separate cables from noise
sources, including power cables of peripheral devices and control I/O.
In the conduit, arrange cables only for the CSD-709. Avoid joint use with other lines
in the conduit.
Ground the CSD-709 based on Type D single grounding using a protective ground
connector. Also, do not use the grounding line of the CSD-709 to ground the power
supply system.
