Precautions on Operating and Storage Environments
1. Operating Ambient Temperature
The rated value for the ambient operating temperature of the G3NA
is for when there is no heat build-up. For this reason, under
conditions where heat dissipation is not good due to poor ventilation,
and where heat may build up easily, the actual temperature of the
G3NA may exceed the rated value resulting in malfunction or
burning.
When using the G3NA, design the system to allow heat dissipation
sufficient to stay below the
Load Current vs. Ambient Temperature
characteristic curve. Note also that the ambient temperature of the
G3NA may increase as a result of environmental conditions (e.g.,
climate or air-conditioning) and operating conditions (e.g., mounting
in an airtight panel).
2. Transportation
When transporting the G3NA, observe the following points. Not doing
so may result in damage, malfunction, or deterioration of
performance characteristics.
•
Do not drop the G3NA or subject it to severe vibration or shock.
•
Do not transport the G3NA if it is wet.
•
Do not transport the G3NA under high temperatures or humidity.
•
Do not transport the G3NA without packing it properly.
3. Vibration and Shock
Do not subject the G3NA to excessive vibration or shock. Otherwise
the G3NA may malfunction and internal components may be
deformed or damaged, resulting in failure of the G3NA to operate.
To prevent the G3NA from abnormal vibration, do not install the
G3NA in locations or by means that will subject it to vibration from
other devices, such as motors.
4. Solvents
Do not allow the G3NA or the resin portion of the Fan’s thermostat to
come in contact with solvents, such as thinners or gasoline. Doing so
will dissolve the markings on the G3NA.
5. Oil
Do not allow the G3NA terminal cover to come in contact with oil.
Doing so will cause the cover to crack and become cloudy.

Operation
1. Leakage Current
A leakage current flows through a snubber circuit in the G3NA even
when there is no power input. Therefore, always turn OFF the power
to the input or load and check that it is safe before replacing or wiring
the G3NA.
2. Screw Tightening Torque
Tighten the G3NA terminal screws properly. If the screws are not
tight, the G3NA will be damaged by heat generated when the power
is ON. Perform wiring using the specified tightening torque.
3. Handling Relays
Do not mount the G3NA when your hands are oily or dirty, e.g., with
metal powder. These may cause G3NA failure.
4. Do Not Drop
Be careful not to drop a Relay or Heat Sink onto any part of your
body while working. Injury may result. This is particularly true for the
High-capacity Heat Sink (Y92B-P250NF), which weighs 2.5 kg.
