For the control panel, use the product having sufficient strength, fire protectiveness
and shielding property to an installation environment.

24 V DC of the power supply must be supplied from the circuit double/reinforced
insulated from the main power supply (MAINS).

Caution for compliance with the LVD directive (EN61010-2-201:2013)

*1

To an external connection port other than AC power supply terminal and AC input/
output terminal, connect the circuit separated from a dangerous voltage by a
double/reinforced insulation.

Between the commons having the adjacent relay output terminals, if an external
power supply is higher than 120 V AC, the insulation is basic. Therefore, when
using 120 V AC or higher external power supply and 30 V DC/AC or lower external
power supply between the adjacent commons, do not handle 30 V DC/AC or lower
external power supply as a touchable part, (When handling 30 V DC/AC or lower
external power supply as a touchable part, add a basic insulation.)

Do not wire two or more crimp terminals to one terminal. (If the wiring with two or
more wires is needed, take an appropriate action such as adding an external
terminal.)

For crimp terminals to be used for the wiring applied with 30 V AC or higher, use the
products with insulating sleeves.

Cutoff device such as a breaker or a circuit protector should be installed in
accordance with the following precautions.

-

Use EN60947-1 or EN60947-3 standards.

-

Place the cutoff device so that it can be operated easily.

-

Specify that the cutoff device is for this equipment.

*1 For the time of compliance with the LVD directive (EN61010-2-201:2013), refer

to the manual of the PLC to be connected.

2. General specifications and Installation

DESIGN
PRECAUTIONS

Make sure to have the following safety circuits outside the PLC to ensure
safe system operation even during external power supply problems or PLC
failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a

protection circuit, an interlock circuit for opposite movements (such as
normal vs. reverse rotation), and an interlock circuit (to prevent damage
to the equipment at the upper and lower positioning limits).

2) Note that when the PLC CPU detects an error, such as a watchdog timer

error, during self-diagnosis, all outputs are turned off. Also, when an error
that cannot be detected by the PLC CPU occurs in an input/output control
block, output control may be disabled.
External circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.

3) Note that when an error occurs in a relay output device, the output could

be held either on or off.
For output signals that may lead to serious accidents, external circuits
and mechanisms should be designed to ensure safe machinery operation
in such a case.

DESIGN
PRECAUTIONS

Do not bundle the control line together with or lay it close to the main circuit
or power line. As a guideline, lay the control line at least 100mm (3.94") or
more away from the main circuit or power line.
Noise may cause malfunctions.

Install module so that excessive force will not be applied to the terminal
blocks.
Failure to do so may result in wire damage/breakage or PLC failure.

INSTALLATION 
PRECAUTIONS

Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
