z SAFETY PRECAUTIONS z

(Read these precautions before using.)

When using this equipment, thoroughly read this manual. Also pay careful
attention to safety and handle the module properly.
These precautions apply only to this equipment.
Refer to the user’s manual of the CPU module to use for a description of the
PLC 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

DANGER

CAUTION

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
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.

CAUTION

may also

[DESIGN PRECAUTIONS]

DANGER

z Some failures of the GOT main unit, communication module,

communication board or cable may keep the outputs on or off.
An external monitoring circuit should be provided to check for output
signals which may lead to a serious accident.
Not doing so can cause an accident due to false output or malfunction.

z If a communication fault (including cable disconnection) occurs during

monitoring on the GOT, communication between the GOT and PLC CPU is
suspended and the GOT becomes inoperative.
For bus connection: The CPU becomes faulty and the GOT inoperative.
For other than bus connection: The GOT becomes inoperative.
A system where the GOT is used should be configured to perform any
significant operation to the system by using the switches of a device other
than the GOT on the assumption that a GOT communication fault will
occur.
Not doing so can cause an accident due to false output or malfunction.

A

[DESIGN PRECAUTIONS]

DANGER

z Do not use the GOT as the warning device that may cause a serious

accident.
An independent and redundant hardware or mechanical interlock is required
to configure the device that displays and outputs serious warning.
Failure to observe this instruction may result in an accident due to incorrect
output or malfunction.

z Incorrect operation of the touch switch(s) may lead to a serious accident if

the GOT backlight is gone out.
When the GOT backlight goes out, the display section turns black and
causes the monitor screen to appear blank, while the input of the touch
switch(s) still remains active.
This may confuse an operator in thinking that the GOT is in “screensaver”
mode, who then tries to release the GOT from this mode by touching the
display section, which may cause a touch switch to operate.
Note that the following occurs on the GOT when the backlight goes out.

• The monitor screen disappears even when the screensaver is not set.

• The monitor screen will not come back on by touching the display section,

even if the screensaver is set.

CAUTION

z Do not bundle the control and communication cables with main-circuit,

power or other wiring.
Run the above cables separately from such wiring and keep them a
minimum of 100mm apart.
Not doing so noise can cause a malfunction.

[MOUNTING PRECAUTIONS]

DANGER

z Before installing or removing the GOT main unit to or from an enclosure,

always switch off the GOT power externally in all phases.
Not doing so can cause a module failure or malfunction.

z Before loading or unloading the communication board, communication

module, External I/O module or memory board to or from the GOT, always
switch off the GOT power externally in all phases.
Not doing so can cause a module failure or malfunction.

5.4 The Precautions on the Wiring

DANGER

z Completely turn off the externally supplied power used in the system when

installing or placing wiring. Not completely turning off all power could result
in electric shock, damage to the product.

CAUTION

z Be sure to ground the FG terminal and LG terminal of the GOT power

supply section to the protective ground conductor. Not doing so could
result in electric shock or erroneous operation.

z When wiring in the GOT power section, 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 erroneous operation.

z Tighten the terminal screws of the GOT power supply section within the

specified torque range.
If the terminal screws are loose, it could result in short circuits, erroneous
operation or erroneous operation.
Tightening the terminal screws too far may cause damages to the screws
and/or the module, resulting in fallout, short circuits, or erroneous
operation.

z Be sure there are no foreign substances such as sawdust or wiring debris

inside the modle GOT main unit.

y General view of noise countermeasures

There are two types of noise: radiated noise, which is transmitted through
the air, and conducted noise, which is transmitted through a connection
wire. In noise countermeasures, the both two types of noise should be taken
into account. As the noise countermeasures, there are the following three
methods.
(1) Block noise

(a) Keep signal wires away from a possible noise source as power wires

or high-power driving circuits.

(b) Shield signal wires.

(2) Reduce generated noise

(a) Reduce the noise generated from high-power motor drive circuits.

(3) Ground noise without fail

(a) Earth the grounding wire to the ground without fail.
(b) Use a grounding wire as thick and short as possible to ensure low

grounding impedance.

(c) Separate the grounding between power and control systems.

12

(1) Power supply wiring

y Separate the GOT's power supply line from the lines for I/O devices and

power devices as shown below.
When there is much noise, connect an insulation transformer.

I/O power supply

Main circuit equipment

y 100VAC, 200VAC and 24VDC wires should be twisted as dense as

possible.
Connect the modules with the shortest distance.
Also, to reduce the voltage drop to the minimum, use the thickest wires
possible (0.75 to 2mm

2

).
Use a solderless terminal for M3 screw. Also, be sure to tighten the M3
screw within tightening torque 0.55 to 0.88 Nym in order not to cause
trouble.

y Do not bundle the 100VAC, 200VAC and 24VDC wires with, or run them

close to, the main circuit (high voltage, large current) and I/O signal
lines. Reserve a distance of at least 100 mm from adjacent wires.

y As a countermeasure to power surge due to lightening, connect a surge

absorber for lightening as shown below.

Lightening surge absorber connection diagram

AC

E1

Surge absorber for lightening

GOT

E2

POINT

(1) Separate the ground of the surge absorber for lightening (E1) from

that of the GOT (E2).

(2) Select a surge absorber for lightening whose power supply voltage

does no exceed the maximum allowable circuit voltage even at the
time of maximum power supply voltage elevation.

13

(2) Grounding

y For grounding, perform the following:

Use a dedicated grounding wire as far as possible. (Grounding
resistance of 100

or less.)

y When a dedicated grounding cannot be performed, use (2) Common

Grounding shown below.
Also, be sure to take noise countermeasures other than grounding.

POINT

(1) Use the thickest possible (max. 2 mm2 (14 AWG)) wires for the

100/200 VAC and 24 VDC power cables. Be sure to twist these wires
starting at the connection terminals. To prevent a short-circuit should
any screws loosen, use solderless terminals with insulation sleeves.

(2) When the LG terminals and FG terminals are connected, be sure to

ground the wires. Do not connect the LG terminals and FG terminals
to anything other than ground. If LG terminals and FG terminals are
connected without grounding the wires, the PLC may be susceptible
to noise.
In addition, since the LG terminals have potential, the operator may
receive an electric shock when touching metal parts.

5.6 Connection Cable Wiring

• Do not bind connection cables with the main circuit (high voltage, heavy
current) or I/O signal cables, or lay them close to each other.
