[DESIGN PRECAUTIONS]

DANGER

z Do not bunch the control wires or communication cables with

the main circuit or power wires, or lay them close to each other.
As a guide, separate the lines by a distance of at least 100 mm
(3.94 inch) otherwise malfunctions may occur due to noise.

[INSTALLATION PRECAUTIONS]

DANGER

z Be sure to shut off all phases of the e xter na l powe r su pp ly used

by the system before mounting or removing this unit to/from the
GOT.
Not doing so can cause a unit failure or malfunction.

z Before connecting the Bus connection cable to this unit, always

shut off GOT power and PLC CPU power externally in all
phases.Not doing so can cause a malfunction.

CAUTION

z Use this unit in the environment given in the general

specifications of the GT15 User's Manual.Not doing so can
cause an electric shock, fire, malfunction or product damage or
deterioration.

z When installing this unit to the GOT, fit it to the connection

interface of the GOT and tighten the mounting screws in the
specified torque range.
Undertightening can cause a drop, failure or malfunction.
Overtightening can cause a drop, failure or malfunction due to
screw or unit damage.

[WIRING PRECAUTIONS]

DANGER

z Be sure to shut off all phases of the e xter na l powe r su pp ly used

by the system before wiring.
Failure to do so may result in an electric shock, product damage
or malfunctions.

CAUTION

z Use crimp-contact, pressure-displacement or soldering to wire

the connectors for external connections properly using the
manufacturer-specified tools.
If the connection is incomplete, it may cause the module to shor t
circuit, catch fire, or malfunction.

z Connect the connectors to the unit securely.
z Always secure the cables connected to the unit, e.g. run them in

conduits or clamp them.
Not doing so can cause unit or cable damage due to dangling,
moved or accidentally pulled cables or can cause a malfunction
due to a cable contact fault.

[STARTUP AND MAINTENANCE PRECAUTIONS]

DANGER

z Before starting cleaning, always shut off GOT power externally

in all phases. Not doing so can cause a unit failure or
malfunction.

CAUTION

z Do not disassemble or modify any unit.

This will cause failure, malfunction, injuries, or fire.

z Do not touch the conductive areas and electronic parts of this

unit directly.
Doing so can cause a unit malfunction or failure.

z Exercise care to avoid foreign matter such as chips and wire

offcuts entering the unit.
Not doing so can cause a fire, failure or malfunction.

z Do not hold the cable part when unplugging any cable

connected to the unit. Doing so can cause unit or cable damage
or a malfunction due to a cable contact fault.

z Always make sure to touch the grounded met al to discha rge the

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

[DISPOSAL PRECAUTIONS]

CAUTION

z Dispose of this product as industrial waste.

[TRANSPORTATION PRECAUTIONS]

CAUTION

z Make sure to transport the GOT main unit and /or relevant u nit(s)

in the manner they will not be exposed to the impact exceeding
the impact resistance described in the general specifications of
the GT15 User's Manual, as they are precision devices.
Failure to do so may cause the unit to fail.
Check if the unit operates correctly after transportation.

4. Installation Procedure

4.1 Serial communication unit installation

The following figures show an example of the GT15-RS2-9P/
RS4-9S installation.The installation of the GT15-RS4-TE
follows the same procedure.

(1) Power off the GOT.
(2) Remove the one extension unit covers of the GOT.

(3) Fit the Ethernet communication unit along th e groove

of the GOT case.

(4) Fasten the Ethernet communication unit by tighte ning

its mounting screws (2 places) with tightening torque

0.36 to 0.48 N•m.

(5) When installing a communication unit on the outer

layer, remove the connector cover and peel the seal.
When not mounting any communication unit on the
outer layer, stick accessory labels on the top of
mounting screws (2 places) to cover the top of them
in order to avoid receiving electrostatic.
Keep the connector cover fixed.
Keep the seal stuck as it is.

(2) Fasten the terminal block by tightening the terminal

block fixing screws (2 places) with the tightening
torque of 0.20 to 0.25 N•m.
