Precautions for All Relays
Refer to the Safety Precautions section for each Relay for specific precautions applicable to that Relay.
These precautions are required to ensure safe operation.

Do not touch the charged Relay terminal area or the charged
socket terminal area while the power is turned ON. Doing so may
result in electric shock.
Do not use a Relay for a load that exceeds the Relay's switching
capacity or other contact ratings. Doing so will reduce the specified
performance, causing insulation failure, contact welding, and
contact failure, and the Relay itself may be damaged or burnt.
Do not drop or disassemble Relays.
Doing so may reduce Relay characteristics and may result in
damage, electric shock, or burning.
Relay durability depends greatly on the switching conditions.
Confirm operation under the actual conditions in which the Relay
will be used. Make sure the number of switching operations is
within the permissible range. If a Relay is used after performance
has deteriorated, it may result in insulation failure between circuits
and burning of the Relay itself.

Do not apply overvoltages or incorrect voltages to coils, or
incorrectly wire the terminals. Doing so may prevent the Relay from
functioning properly, may affect external circuits connected to the
Relay, and may cause the Relay itself to be damaged or burnt.
Do not use Relays where flammable gases or explosive gases may
be present. Doing so may cause combustion or explosion due to
Relay heating or arcing during switching.
Perform wiring and soldering operations correctly and according to
the instructions contained in Precautions for Correct Use given
below. If a Relay is used with faulty wiring or soldering, it may
cause burning due to abnormal heating when the power is turned
ON.
