● Power Supply Selection
Use a DC power supply satisfying the following requirements.
• The secondary circuit of the DC power supply must be isolated from the primary cir-
cuit by double insulation or reinforced insulation.
• The output characteristic requirements defined in UL 508 for class 2 circuits or con-
trol voltage current circuits are satisfied.
• The output hold time must be 20 ms or longer.
• The DC power supply must be an SELV power supply that satisfies the requirements
of IEC/EN 60950-1 and EN 50178.
● Periodic Inspections and Maintenance
• Disconnect the G9SP-series Controller from the power supply before replacing the Controller. Devices
connected to the G9SP-series Controller may operate unexpectedly.
• Do not disassemble, repair, or modify the G9SP-series Controller. Doing so may lead to loss of safety
functions.
● Disposal
Be cautious not to injure yourself when dismantling the G9SP-series Controller.
