Perform wiring of the AD75 correctly while checking the terminal arrangement.
(For the terminal arrangement of the external device connection connector, refer
to section 3.5.2 "Signal layout of external device connection connector.")
Solder or crimp the external device connection connector correctly.
An improperly soldered or crimped connector may cause malfunctions.
Be careful to avoid entry of chips, wiring dust and so on inside the AD75.
Otherwise fire, failure or malfunction may be caused.
Be sure to install a cover for the external device connection connector if no
external device is connected. Otherwise malfunction may be caused.
Connect the external device connection connector and peripheral device
connection connector with the connector of the AD75. Check that the connector
snaps. An improperly connected connector will cause poor continuity, possibly
causing erroneous inputs or outputs.
Do not pull the cable when removing the cable from the AD75 or drive unit. Hold
and pull the connector connected to the AD75 or drive unit. If the cable
connected to the AD75 or drive unit is pulled, a malfunction may be caused. As
well, the AD75, drive unit or cable may be broken.
Disconnect the external device connection connector when the system is
stopped.
If the external device connection connector is disconnected during operation of
the system, the system will be stopped.
Do not tie the AD75 cable with the main circuit cable, power cable, or a load
cable for other than the programmable logic controller or do not route the AD75
cable near them. Separate these by 100 mm as a measure. Otherwise noise,
surge or induction may cause a malfunction.
When routing the AD75 cable near a power cable at a distance smaller than 100
mm, use a shielded cable for a countermeasure against noise. Connect the
shielding wire of the shielded cable securely to the panel of the AD75.
