Safety Precautions
■ 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.

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 occasion-
ally cause minor burns. Do not touch the G3NA or the
heat sink either while the power supply is ON, or imme-
diately after the power is turned OFF.
The internal snubber circuit is charged and may occa-
sionally 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 com-
pleting 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.
