[Design Precautions]

CAUTION

z Do not bunch AS-i cable with the main circuit or power wires, or install them

close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.

[Installation Precautions]

CAUTION

z Use the programmable controller in an environment that meets the general

specifications in CPU module User’s Manual.
Using the programmable controller in an environment outside the range of
the general specifications could result in electric shock, fire, erroneous
operation, and damage to or deterioration of the product.

z Do not touch conductive parts or electronic components of the module with

your bare hands.
This could cause malfunction or failure of the module.

z While pressing the lever on the lower part of the module, fully insert the

module fixing latch into the hole of the base unit, snap the module into place,
and tighten the module fixing screws with the specified torque.
Failure to observe this could result in damage to the screws or module,
module falling, short or misoperation.
If the screws are tightened excessively, it may damage the screws and
cause the module to short-circuit, malfunction or fall off.

z Always shut off all phases of the programmable controller power supply and

AS-i power supply externally before mounting or removing the module.
Failure to shut off all phases could lead to product damage.

[Wiring Precautions]

DANGER

z Switch off all phases of the programmable controller power supply and AS-i

power supply outside the programmable controller before starting installing
or wiring work.
There is a risk of electric shock or malfunction.

CAUTION

z Always confirm the products terminal layout before wiring to the module.

Incorrect wiring could lead to fires or faults.

z Wiring installation screws to the specified torque.

If a wiring installation screws is not tightened to the specified torque, the
module may fall out, short circuit, or malfunction.
If a wiring installation screws is tightened excessively, exceeding the
specified torque, the module may fall out, short circuit, or malfunction due to
breakage of the screw or the module.

z Make sure that no foreign matter such as chips or wire offcuts gets inside the

module.
It will cause fire, failure, or malfunction.

z A label is installed at the upper part of a module to prevent the entry of foreign

matters.
Do not remove the label during wiring.
However, be sure to remove it for heat dissipation during system operation.

z To connect the AS-i cable to the module, the cable must be securely fixed.

Please be sure to run it in a duct, or clamp it.
Failure to observe this could cause the unstable cable connection, resulting
in damage to the cable or module by carelessly pulling the cable, or the
system malfunction due to poor cable connection.

z When removing AS-i cable from a module, do not pull it out by hand.

Always be sure to unscrew the module mounting screws in advance.
If the cable is pulled while being connected to the module, it could cause
damage to the cable or module, or the system malfunction due to poor cable
connection.

3. Loading and Installation

The following section explains the precautions when handling the QJ71AS92,
from the time they are unpacked until they are installed.
For more details on the module installation, see the user's manual for the
programmable controller CPU used.

3.1 Handling

(1) Do not drop the module case and connector or subject it to heavy impact

since it is made of resin.

(2) Always make sure to touch the grounded metal to discharge the electricity

charged in the body, etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module.

(3) Tighten the screws such as module fixing screws within the following

ranges.

Screw location Tightening torque range
Module fixing screw (normally not required) (M3 screw) *1 0.36 to 0.48 Nym
Communication connector installation screw 0.40 to 0.50 Nym

Communication connector wiring installation screw 0.50 to 0.60 Nym

*1 The module can be easily fixed onto the base unit using the hook at the

top of the module.
However, it is recommended to secure the module with the module
fixing screw if the module is subject to significant vibration.

5. Wiring

5.1 Precautions against wiring

Precautions of external wiring of QJ71AS92 are explained below.

(1) The overall distance is up to 100m.

The distance can be increased 100m by use of one repeater.
Since up to two repeaters can be used in series, the overall distance can be
increased up to 300m.

(2) Do not bunch AS-i cable with the main circuit or power wires, or install them

close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.

5.2 Wiring

This clause explains wiring to the connector of QJ71AS92.
Be sure connect the QJ71AS92 to the AS-i system with the AS-i cable.

An example of wiring to the QJ71AS92 is shown below.
(Confirm each module being used for the AS-i power supply and slave terminal
layout.) Strip the AS-i cable about 7mm and plug it to the connector.
