[Wiring Precautions]
[Startup and Maintenance Precautions]
CAUTION
●
Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
●
A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring. Do not remove the film during wiring. Remove it for heat
dissipation before system operation.
●
Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
●
When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. Pulling the cable connected to the module may
result in malfunction or damage to the module or cable.
●
Use 1000BASE-T-compliant Ethernet cables for Ethernet connection. For the maximum station-to-
station distance and the overall cable distance, follow the specifications in this manual. If not, normal
data transmission is not guaranteed.
WARNING
●
Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
●
Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the module fixing screw. Failure to do so may result in electric shock.
