[Design Precautions]

CAUTION

zDo 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

zUse 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.

zDo not touch conductive parts or electronic components of the module with

your bare hands.

This could cause malfunction or failure of the module.

zWhile 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.

zAlways 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.

-3

[Wiring Precautions]

DANGER

zSwitch 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

zAlways confirm the products terminal layout before wiring to the module.

Incorrect wiring could lead to fires or faults.

zWiring 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.

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

module.

It will cause fire, failure, or malfunction.

zA 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.

zTo 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.

zWhen 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.

Compliance with the EMC and Low Voltage Directives

(1) For programmable controller system

To configure a system meeting the requirements of the EMC and Low

Voltage Directives when incorporating the Mitsubishi programmable

controller (EMC and Low Voltage Directives compliant) into other

machinery or equipment, refer to Chapter 9 "EMC AND LOW VOLTAGE

DIRECTIVES" of the QCPU User's Manual (Hardware Design,

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.

3.2 Installation Environment

Refer to user's manual of the CPU module used.
