Operation manual
WARNING
This is the Operation Manual for the G9SR Safety Relays.
Obey the following warnings during system construction to ensure that safety-related
components are configured to enable the system functions to sufficiently operate.
● Risk Assessment
The proper use of the safety devices described in this manual as they relate to
installation conditions and mechanical performance and functions is a prerequisite
for its use.
When selecting or using the safety devices, risk assessment must be performed
during the development stage of the equipment or facilities to identify potential
danger factors in equipment or facilities in which the safety devices are to be applied.
Suitable safety devices must be selected under the guidance of a sufficient risk
assessment system. An insufficient risk assessment system may result in the selection
of unsuitable safety devices.

● Safety Measures
When using this safety device to build systems containing safety-related components
for equipment or facilities, the system must be designed with the full understanding
of and conformance to international standards, such as those listed below, and/or
standards in related industries.

● Role of Safety Devices
The safety devices are provided with safety functions and mechanisms as stipulated
in relevant standards, but suitable designs must be used to enable these functions and
mechanisms to operate properly inside system constructions containing safety-related
components. Build systems that enable these functions and mechanisms to perform
properly, based on a full understanding of their operation.
