SAFETY PRECAUTIONS

(Always read these instructions before using this equipment.)

Before using this product, please read this manual and the relevant manuals
introduced in this manual carefully and pay full attention to safety to handle the
product correctly.
The instructions given in this manual are concerned with this product. For the
safety instructions of the programmable controller system, please read the User’s
Manual for the CPU module.
In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".

Indicates that incorrect handling may cause

DANGER

CAUTION

Note that the CAUTION level may lead to a serious consequence according
to the circumstances.
Always follow the instructions of both levels because they are important to
personal safety.

Please save this manual to make it accessible when required and always forward
it to the end user.

hazardous conditions, resulting in death or severe
injury.

Indicates that incorrect handling may cause
hazardous conditions, resulting in medium or slight
personal injury or physical damage.

[Design Precautions]

CAUTION

Do not bunch the control wires or pulse input lines with the main circuit or
power wires, or install them close to each other.They should be installed 150
mm (5.91 inch) or more from each other.Not doing so could result in noise
that would cause erroneous operation.

A-1

[Installation Precautions]

CAUTION

Use the programmable controller in the environment conditions given in the
general specifications of the User's Manual for the CPU module.
Using this 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.

While pressing the installation lever located at the bottom of module, insert
the module fixing tab into the fixing hole in the base unit until it stops. Then,
securely mount the module with the fixing hole as a supporting point.
Incorrect loading of the module can cause a malfunction, failure or drop.
When using the programmable controller in the environment of much
vibration, tighten the module with a screw.

Tighten the screw in the specified torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage
to the screw or module.

Completely turn off the externally supplied power used in the system before
mounting or removing the module.
Not completely turning off all power could result in electric shock or damage
to the product.

Do not directly touch the module's conductive parts or electronic
components.
Touching the conductive parts could cause an operation failure or give
damage to the module.

A-2

[Wiring Precautions]

CAUTION

When wiring/connecting the connector, properly press, crimp or solder the
connector using the tools specified by the manufactures and attach the
connector to the module securely.

Be sure there are no foreign substances such as sawdust or wiring debris
inside the module.
Such debris could cause fires, damage, or erroneous operation.

The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat
dissipation.

Be sure to place the cables connected to the module in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in
damage to the module and/or cables, or malfunctions due to poor cable
connection.

When disconnecting the cable, do not pull it by holding the cable part.
Disconnect the cable with connector with holding the connector plugged into
the module. Pulling the cable part with the cable still connected to the module
may cause a malfunction or damage to the module and/or cable.

Always ground the shielded cable on the encoder side (relay box). Failure to
do may cause a malfunction.

When wiring in the programmable controller, be sure that it is done correctly
by checking the product's rated voltage and the terminal layout.
Connecting a voltage different from the rated voltage or incorrect wiring may
result in a fire or failure.

3. IMPLEMENTATION AND INSTALLATION

3.1 Handling Precautions

The following explains the precautions for handling the module.

(1) Do not drop the module case and/or connector or apply a strong

impact to it.

(2) Do not remove the printed-circuit board of the module from the

case.
Doing so will cause failure.

(3) Be sure there are no foreign substances such as sawdust or wiring

debris inside the module.
Such debris could cause fires, damage, or erroneous operation.

(4) The module has an ingress prevention label on its top to prevent

foreign matter, such as wire offcuts, from entering the module
during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because
of heat dissipation.

(5) Tighten the fixing screws within the following torque ranges.

Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to
damage to the screw or module.

Table 3.1 Tightening torque range of module fixing screw

Connector screw (M2.6 screw) 0.20 to 0.29 N m

* 1 The module can be easily mounted to a base unit, using the hook on the

upper part of the module.However, it is recommended to secure it with the
module fixing screws when used in an environment where constant
vibrations may occur.

(6) When mounting the module to the base unit, insert the module

fixing projection into the fixing hole in the base unit, and mount the
module with using the hole as a supporting point.
Incorrect module mounting may cause a malfunction, failure, or
drop of the module.

20cm (7.87inch)
to 30cm (11.81inch)

5.1 Wiring Precautions

(1) Inputting a signal of different voltage may result in a malfunction or

mechanical failure.

(2) For 1-phase input, always perform pulse input wiring on the phase

A side.

(3) When pulse status noise is input, the QD63P6 may miscount.

(4) Take the following measures against noise for high-speed pulse

input.

(a) Always use a shielded twisted pair cable and provide

grounding.

(b) Wire the shielded twisted pair cables so as not to be in parallel

with wires causing much noise such as power lines or I/O
wires while keeping a distance of at least 150 mm (5.91 inch)
between such wires. Also install the shielded twisted pair
cables as short as possible.

(5) When wiring the QD63P6 and an encoder, separate the power

supplycable and signal line.

(6) To conform the wiring to the EMC and Low Voltage Directives,

ground the shielded twisted pair cables to a control panel with the
AD75CK cable clamp (manufactured by Mitsubishi Electric
Corporation).
