DANGER

z Completely turn off the externally supplied power used in the system when installing or

placing wiring.

Not doing so may cause electric shock or damage to the product.

5.1 Wiring Precautions

(1) Always confirm the terminal layout before connecting the wires to the

QD75.

(2) Correctly solder the external wiring connector. An incomplete soldering

could lead to malfunctioning.

(3) Make sure that foreign matter such as cutting chips and wire scraps does

not enter the QD75. Failure to observe this could lead to fires, faults or

malfunctioning.

(4) A protective label is attached on the top of the QD75 to avoid foreign

matter such as wire scraps from entering inside during wiring process. Do

not remove the label until the wiring is completed. Before starting the

system, however, be sure to remove the label to ensure heat radiation.

(5) Securely mount the external device connector to the connector on the

QD75 with two screws.

(6) Do not disconnect the external wiring cable connected to the QD75 and

the drive unit by pulling the cable section. When the cable has a

connector, be sure to hold the connector connected to the QD75 and the

drive unit. Pulling the cable while it is connected to the QD75 and the

drive unit may lead to malfunctioning or damage of the QD75 and the

drive unit or cable.

(7) Do not bundle or adjacently lay the connection cable connected to the

QD75 external I/O signals or drive unit with the main circuit line, power

line, or the load line other than that for the programmable controller.

Separate these by 100mm as a guide. Failure to observe this could lead

to malfunctioning caused by noise, surge, or induction.

(8) The shielded cable for connecting QD75 can be secured in place.

If the shielded cable is not secured, unevenness or movement of the

shielded cable or careless pulling on it could result in damage to the

QD75 or drive unit or shielded cable or defective cable connections could

cause mis-operation of the unit.
