[WIRING PRECAUTIONS]
CAUTION
Always ground the shielded cables for the programmable controller.
There is a risk of electric shock or malfunction.
For wiring and connection, properly press, crimp or solder the connector with
the tools specified by the manufactures and attach the connector to the
module securely.
Be careful to prevent foreign matter such as dust or wire chips from entering
the module.
Failure to do so may cause a fire, failure or malfunction.
A protective film is attached to the module top to prevent foreign matter such
as wire chips from entering the module during wiring.
Do not remove the film during wiring.
Be sure to remove it for heat dissipation before system operation.
Be sure to place the cables connected to the module in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in
damage to the module and/or cables, or malfunctions due to poor cable
connection.
When disconnecting the external wiring cable connected to the module, do
not pull it by holding the cable part. Disconnect the cable with connector with
holding the connector plugged into the module. Pulling the cable part with the
cable still connected to the module may cause a malfunction or damage to
the module and/or cable.
Always place the thermocouple at least 100mm (3.94inch) away from the
main circuit cables and AC control lines. Fully keep it away from highvoltage
cables and circuits, which include high frequency waves, such as an
inverter's load circuit. Not doing so will cause the module more susceptible to
noises, surges and inductions.
Do not place a module near the equipment that generates magnetic noise.
