Safety Precautions
Refer to Safety Precautions for All Solid State Relays.
■ Precautions for Safe Use
Although OMRON continuously strives to improve the quality and
reliability of our relays, the G3NA contains semiconductors, which
are generally prone to occasional malfunction and failure.
Maintaining safety is particularly difficult if a relay is used outside of
its ratings. Always use the G3NA within the rated values. When using
the G3NA, always design the system to ensure safety and prevent
human accidents, fires, and social damage even in the event of
G3NA failure, including system redundancy, measures to prevent
fires from spreading, and designs to prevent malfunction.
1. G3NA malfunction or fire damage may occasionally occur. Do not
2. Heat Dissipation
Touching the charged section may occasionally cause
minor electric shock. Do not touch the G3NA terminal
section (the charged section) when the power supply
is ON. Be sure to attach the cover before use.
The G3NA and heat sink will be hot and may
occasionally cause minor burns. Do not touch the
G3NA or the heat sink either while the power supply is
ON, or immediately after the power is turned OFF.
The internal snubber circuit is charged and may
occasionally cause minor electric shock. Do not touch
the G3NA’s main circuit terminals immediately after
the power is turned OFF.
Be sure to conduct wiring with the power supply turned
OFF, and always attach the terminal cover after
completing wiring. Touching the terminals when they
are charged may occasionally result in minor electric
shock.
Do not apply a short-circuit to the load side of the
G3NA. The G3NA may rupture. To protect against
short-circuit accidents, install a protective device, such
as a quick-burning fuse, on the power supply line.

• Tighten the G3NA screws securely.
• Tighten the heat sink screws securely.
When using the High-capacity Heat Sink (Y92B-P250NF), always
use a thermostat or other method to protect from overheating in
the event that the fan stops.
When the fan is operating, do not touch the fan blades with any
part of your body or allow foreign matter to come into contact with
the blades. Always attach the enclosed finger guard when using
the G3NA.
• Only use the G3NA with loads that are within the rated values.
• Use a power supply within the rated frequency range. Using a
