3: INSTALLATION AND WIRING

Introduction

This chapter describes the methods and precautions for installing and wiring Web server CPU modules.
Before starting installation and wiring, be sure to read “Safety Precautions” in the beginning of this manual and

understand precautions described under Warning and Caution.

Installation Location

• Turn off the power to the Web server CPU module before starting installation, removal, wiring,
maintenance, and inspection of the Web server CPU module. Failure to turn power off may cause electrical
shocks or fire hazard.

• Emergency stop and interlocking circuits must be configured outside the Web server CPU module. If such a
circuit is configured inside the Web server CPU module, failure of the Web server CPU module may cause
disorder of the control system, damage, or accidents.

• Special expertise is required to install, wire, program, and operate the Web server CPU module. People
without such expertise must not use the Web server CPU module.

Warning

• Prevent metal fragments and pieces of wire from dropping inside the Web server CPU module housing. Put
a cover on the Web server CPU modules during installation and wiring. Ingress of such fragments and chips
may cause fire hazard, damage, or malfunction.

• Do not touch the connector pins with hand, otherwise electrostatic discharge may damage the internal
elements.

• Keep the Web server CPU module wiring away from motor lines.

Caution

The Web server CPU module must be installed correctly for optimum performance.
The Web server CPU module is designed for installation in a cabinet. Do not install the Web server CPU module outside

a cabinet.
The environment for using the Web server CPU module is “Pollution degree 2.” Use the Web server CPU module in

environments of pollution degree 2 (according to IEC 60664-1).
Make sure that the operating temperature does not drop below 0°C or exceed 55°C. If the temperature does exceed

55°C, use a fan or cooler.

Mount the Web server CPU module on a vertical plane as shown at
right.

To eliminate excessive temperature build-up, provide ample
ventilation. Do not install the Web server CPU module near, and
especially above, any device which generates considerable heat, such
as a heater, transformer, or large-capacity resistor. The relative
humidity should be above 30% and below 95%.

The Web server CPU module should not be exposed to excessive dust,
dirt, salt, direct sunlight, vibrations, or shocks. Do not use the Web
server CPU module in an area where corrosive chemicals or
flammable gases are present. The modules should not be exposed to
chemical, oil, or water splashes.

Assembling Modules

The following example demonstrates the procedure for assembling the all-in-one 24-I/O type CPU module and an I/O
module together. When assembling slim type CPU modules, take the same procedure.

Disassembling Modules

1. When assembling an input or output module,

remove the expansion connector seal from the 24-I/
O type CPU module.

2. Place the CPU module and I/O module side by side.

Put the expansion connectors together for easy
alignment.

3. With the expansion connectors aligned correctly and

the blue unlatch button in the down position, press
the CPU module and I/O module together until the
latches click to attach the modules together firmly. If
the unlatch button is in the up position, push down
the button to engage the latches.

• Assemble Web server CPU modules together before mounting the modules onto a DIN rail. Attempt to
assemble modules on a DIN rail may cause damage to the modules.

• Turn off the power to the Web server CPU module before assembling the modules. Failure to turn power
off may cause electrical shocks.

Caution

Unlatch Button

1. If the modules are mounted on a DIN rail, first

remove the modules from the DIN rail as described in
“Removing from DIN Rail” on page 3-6.

2. Push up the blue unlatch button to disengage the

latches, and pull the modules apart as shown. When
disassembling slim type CPU modules, take the same
procedure.

• Remove the Web server CPU modules from the DIN rail before disassembling the modules. Attempt to
disassemble modules on a DIN rail may cause damage to the modules.

• Turn off the power to the Web server CPU module before disassembling the modules. Failure to turn
power off may cause electrical shocks.
