WARNING
Electric shock may occur. Do not touch any terminals
while power is being supplied.
Serious injury may possibly occur due to loss of
required safety functions. Do not use the G9SP-series
Controller's test outputs or standard outputs as
safety outputs.
Serious injury may possibly occur due to loss of
required safety functions. Do not use the G9SP-series
Controller's network data as safety data.
Serious injury may possibly occur due to loss of
required safety functions. Do not use indicators on the
G9SP-series Controller for safety operations.
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.
Serious injury may possibly occur due to loss of required
safety functions. Wire the G9SP-series Controller properly
so that the 24 VDC line does NOT touch the outputs
accidentally or unintentionally.
Serious injury may possibly occur due to loss of
required safety functions. Ground the 0V line of the
power supply for external output devices so that the
devices do NOT turn ON when the safety output line
or the test output line is grounded.
Serious injury may possibly occur due to loss of
required safety functions. Perform user testing and
confirm that all of the G9SP-series Controller's
configuration data and operation is correct before
starting system operation.
Serious injury may possibly occur due to loss of
required safety functions. When replacing a G9SP-
series Controller, confirm the model of the Controller
is correct and configure the replacement Controller
suitably and confirm that it operates correctly.
Serious injury may possibly occur due to loss of
required safety functions. When the configuration
data is restored by using a Memory Cassette, a test
must be performed to confirm that the safety devices
function correctly.
Outputs may operate, possibly resulting in serious
injury. Take sufficient safety measures before force-
setting or force-resetting variables in the program.
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.
