Installation and Wiring
Tighen the screws of the module using torque within the following ranges.
Loose screws may cause short circuits, mechanical failures or malfunc
-
tion.
Mounting a module to a base unit
햴 All modules exept the Q66AD-DG:
Secure the module with an additional screw (M3 x 12) to the base unit
if large vibration is expected. This screw is not supplied with the
module.
햴 Q66AD-DG only:
Mount the module fixing bracket. Make sure that the module fixing
bracket is hooked on the 3rd slit viewed from the front of the
Q66AD-DG. Tighten the module mounting screw with the specified
torque.
Wiring
Please observe the following precautions for external wiring:
쎲
Use separate cables for the AC control unit and the external input sig
-
nals of the analog input modules to avoid the influence of AC side
surges and inductions.
쎲
Do not lay signal cables close to the main circuit, high-voltage power
lines, or load lines. Otherwise effects of noise or surge induction are
likely to take place. Keep a safe distance of more than 100 mm from
the above when wiring.
쎲
The shield of the signal cables must be grounded at one end.
E
CAUTION
쎲
Use the product in the environment within the general specifi
-
cations described in the Hardware Manual for the MELSEC
System Q. Never use the product in areas with dust, oily
smoke, conductive dusts, corrosive or flammable gas, vibra
-
tions or impacts, or expose it to high temperature, condensa
-
tion, or wind and rain.
쎲
When drilling screw holes or wiring, cutting chips or wire chips
should not enter ventilation slits. This may cause a short cir
-
cuit. Use the provided dust proof sheet to cover the ventilation
port. Be sure to remove this sheet from the PLC's ventilation
port when the installation work is completed to prevent over
-
heating.
DANGER:
Personnel health and injury warnings.
Failure to observe the precautions described here
can result in serious health and injury hazards.

CAUTION:
Equipment and property damage warnings.
Failure to observe the precautions described here
can result in serious damage to the equipment or
other property.
P
DANGER
쎲
Turn off all phases of the power supply for the PLC and other
external sources before starting the installation or wiring work.

CAUTION
쎲
Do not drop the module or subject it to heavy inpact.
쎲
Do not open or modify a module. Doing so can cause a failure,
malfunction, injury or fire.
쎲
Always insert the module fixing latch of the module into the
module fixing hole of the base unit. Forcing the hook into the
hole will damage the module connector and module.
쎲
Do not touch the conductive or electronic parts of a module
directly. Doing so can cause a unit malfunction or failure.
햲
After switching off the power supply,
insert the module fixing latch into the
module fixing hole of the base unit.
햳
Push the module in the direction of arrow
to load it into the base unit.
