 Safety Precautions

WARNING Indicates a potentially hazardous situation which, if

not avoided, could result in death or serious injury.
Also there may be severe property damage.

Caution

Indicates a potentially hazardous situation, which, if
not avoided, may result in minor or moderate injury,
or property damage.

Refer to the Operation Manual for more detailed information.

 Warnings and Cautions

WARNING Installation, wiring, maintenance and inspection

must be performed by authorized personnel.
Not doing so may result in dangerous
situations.

WARNING Electric shock may occur. Do not touch any

terminals while power is being supplied.

WARNING Serious injury may possibly occur due to loss of

required safety functions. Do not use the G9SR­series relay's test outputs or standard outputs as
safety outputs.

WARNING Serious injury may possibly occur due to loss of

required safety functions. Do not use indicators
on the G9SR-series relay for safety operations.

WARNING Serious injury may possibly occur due to

breakdown of safety outputs or test outputs. Do
not connect loads beyond the rated values to the
safety outputs and test outputs.

WARNING Serious injury may possibly occur due to loss of

required safety functions. Wire the G9SR series
Controller properly so that the 24VDC line does
NOT touch the outputs accidentally or
unintentionally.

WARNING Do not connect the 0V line to PE.

Serious injury may possibly occur due to loss of
required safety functions.

WARNING Serious injury may possibly occur due to loss of

required safety functions. Perform user testing
and confirm that all of the G9SR-series relay’s
configuration data and operation is correct before
starting system operation.

WARNING Serious injury may possibly occur due to loss of

required safety functions. When replacing a
G9SR-series relay, confirm the model of the
Controller is correct and configure the
replacement Controller suitably and confirm that it
operates correctly.

WARNING Serious injury may possibly occur due to loss of

required safety functions. Use devices and parts
related to safety functions according to legal
regulations in the applicable country. Use certified
items compliant with safety standards
corresponding to the intended application.

WARNING Do not try to disassemble, repair, or modify this

product. Doing so may cause the safety functions
to stop working properly.

WARNING Do not use the G9SR safety relays in

environments where flammable or explosive
gases are present. Doing so may result in an
explosion.

WARNING Perform daily and 6-monthly inspections for the

G9SR safety relays. Otherwise, the system may
fail to work properly, resulting in serious injury.

WARNING Do not use the auxiliary output for safety

applications.

Caution

Connect the AD201-□ and EX031-□ units to the
same power supply.

Caution

Do not remove a terminal block while the unit is
powered ON. It may damage the unit.

Caution

Do not remove the 0V connection while the unit is
powered ON. It may damage the unit.

Provide external measure to ensure appropriate overvoltage protection to

30Vdc max.

Refer to the Operation Manual for more detailed information.
