Safety Precautions
Refer to the “Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided Contacts”.
Applicable Safety Category (EN954-1)
G9SA-300-SC Safety Relay Units fall under Safety Category 4.
The above is provided according to circuit examples presented by
OMRON. Therefore, the above may not apply to all operating
environments.
The applicable safety category is determined from the whole safety
control system. Make sure that the whole safety control system meets
EN954-1 requirements.
• Turn OFF the G9SA-300-SC before wiring the G9SA-300-SC. Do
• To conform to IEC61496-1 and UL508 when using the F3SN-A,
• Recommended Power Supplies: S82K, S82J, S82F, or S82F-P
• Do not connect any device other than the F3SN-A, F3SN-B, or
• Be sure to mount both the emitter and the receiver in the correct

not touch the terminals of the G9SA-300-SC while the power is
turned ON, because the terminals are charged and may cause an
electric shock.
F3SN-B, or F3SH-A, ensure that the DC power supply satisfies all
the conditions below.
• The voltage is within the rated power supply voltage range
• The power supply is connected only to the F3SN-A or devices
• The power supply conforms to the EMC Directive (industrial
• The power supply uses double or reinforced insulation between
• The power supply automatically resets overcurrent protection
• The power supply maintains an output holding time of at least
• The power supply satisfies the output characteristic
• The power supply satisfies laws, regulations, and standards
made by OMRON. For details, refer to the Power Supply Selection
Guide (Cat. No. Y102).

Voltage Directive.)
Precautions for Safe Use
Failure Detection for Slow-starting Power Supply
When using a power supply with a long start-up time, if power is
switched on while input has been closed the internal circuits will
detect a power voltage error and the product will not operate. Apply
the voltage to the product once the voltage has reached its rated level.
Installation
The G9SA-300-SC can be installed in any direction.
Wiring
Connecting Inputs
When using more than one G9SA300-SC Unit, do not connect the
same switch to more than one G9SA300-SC Unit. This applies to all
input terminals.
Durability of Contact Outputs
Relay with Forcibly Guided Contact durability depends greatly on the
switching condition. Confirm the actual conditions of operation in
which the Relay will be used in order to make sure the permissible
number of switching operations.
When the accumulated number of operation exceeds its permissible
range, it can cause failure of reset of safety control circuit. In such
case, please replace the Relay immediately. If the Relay is used
continuously without replacing, then it can lead to loss of safety
function.
