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 G9SR-
series 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.

G9SR Safety Relay Units: Family Description
The product family G9SR consists of a BC201 (BC=Basic), an AD201
(AD=Advanced) and an EX031 (EX=Extension) unit to give you flexibility
configuring your specific situation. The AD201-□module can be extended
with max. 2 BC201-□for extra inputs and with max.3 EX031-□-□for extra
outputs.
Operating Environment
Caution The operating environment of the G9SR unit(s) can
have a large effect on the longevity and reliability of
the system. A bad operating environment can lead
to malfunction and other unforeseeable problems
with the system. Make sure that the operating
environment is within the specifications at
installation and remains within the specified
conditions during the life of the system.
Installation Conditions
Space must be provided around the G9SR-series relay, at least 25 mm
from its side surfaces and at least 50 mm from its top and bottom
surfaces, for ventilation, wiring and Unit replacement.
Refer to the Operation Manual, Section Installation and Configuration for
more detailed information.
