DANGER

CAUTION

!SAFETY PRECAUTIONS !

(Read these precautions before using.)

When using Mitsubishi equipment, thoroughly read this manual and the

associated manuals introduced in this manual. Also pay careful attention to

safety and handle the module properly.

These precautions apply only to Mitsubishi equipment. Refer to the CPU

module user's manual for a description of the PC system safety precautions.

These !SAFETY PRECAUTIONS!classify the safety precautions into two

categories: "DANGER" and "CAUTION".

Procedures which may lead to a dangerous condition and

cause death or serious injury if not carried out properly.

Procedures which may lead to a dangerous condition and

cause superficial to medium injury, or physical damage

only, if not carried out properly.

Depending on circumstances, procedures indicated by CAUTION may also

be linked to serious results.

In any case, it is important to follow the directions for usage.

Store this manual in a safe place so that you can take it out and read it

whenever necessary. Always forward it to the end user.

[INSTALLATION PRECAUTIONS]

CAUTION

!Use the PC in an environment that meets the general specificaitons

contained in this manual. Using this PC 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.

!Do not touch the printed circuit board of the module.

It may cause damage or erroneous operation.

!Install so that the pegs on the bottom of the module fit securely into the

base unit peg holes.

Not installing the module correctly or tightening the screws to the terminal

base could result in erroneous operation, damage, or pieces of the product

falling.

A-2

[WIRING PRECAUTIONS]

DANGER

!Completely turn off the external power when installing or placing wiring. Not

completely turning off all power could result in electric shock or damage to

the product.

CAUTION

!When wiring in the PC, be sure that it is done correctly by checking the

product's rated voltage and the terminal layout. Connecting a power supply

that is different from the rating or incorrectly wiring the product could result

in fire or damage.

!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.

!Solder the coaxial cable connector properly. Incomplete soldering may

cause a malfunction.

!Tighten terminal screws to the specified torque.

If a terminal screw is not tightened to the specified torque, it the module may

fall out, short circuit, or malfunction.

If a terminal screw 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.

!Be sure to fix communication cables or power cables leading from the

module by placing them in the duct or clamping them.

Cables not placed in the duct or without clamping may hang or shift,

allowing them to be accidentally pulled, which may cause a module

malfunction and cable damage.

!When removing the communication cable or power cables from the module,

do not pull the cable. When removing the cable with a connector, hold the

connector on the side that is connected to the module.

When removing the cable connected to the terminal block, first loosen the

screws on the terminal block.

Pulling the cable that is still connected to the module may cause malfunction

or damage to the module or cable.

3. Handling

[INSTALLATION PRECAUTIONS]

CAUTION

!Use the PC in an environment that meets the general specificaitons

contained in this manual. Using this PC 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.

!Do not touch the printed circuit board of the module.

It may cause damage or erroneous operation.

!Install so that the pegs on the bottom of the module fit securely into the

base unit peg holes.

Not installing the module correctly or tightening the screws to the terminal

base could result in erroneous operation, damage, or pieces of the product

falling.

3.1 Cable length restrictions between stations.

1) The main modules case is made of plastic, so do not drop it or subject it to

strong impacts.

2) Do not dismount the printed wiring board from the case. It may damage

the module.

3) When wiring, be careful never to let foreign matter from the above module

such as wiring scraps get inside the module. If something goes in, get rid

of it.

4) The module installation screw should be kept within the following range.
