Safety Precautions for All Relays
Precautions for Safe Use
Observe the following precautions to ensure safety.
Do not touch the terminal section (charged section) of the Relay or Socket while power is being supplied. Electric shock may occur.
Never use a Relay for a load that exceeds the contact ratings of the Relay, such as the switching capacity. Doing so may result in reducing Relay performance for insulation failure, contact welding, and contact faults, and might even result in burning or other damage to the Relay itself.
Do not drop the Relay or dismantle it. Doing so may reduce Relay performance and might even result in burning or other damage to the Relay itself.
Relay durability is greatly affected by the switching conditions. Always test the Relay under actual application conditions to confirm applicability and use the Relay only for the number of switching operations that will not affect performance. Continued application of a Relay with reduced performance may result in insulation failure between circuits or in burning in the Relay itself.
Do not apply an overvoltage or incorrect voltage to the coil, and do not wire the terminals incorrectly. Incorrect application may prevent the Relay from performing its designed function, may affect external circuits, and may even result in burning or other damage to the Relay itself.
Do not use the Relay in atmospheres containing inflammable or explosive gases. Switching arcs or Relay heating may result in fire or explosion.
Wire the Relay correctly according to the Precautions for Correct Use when performing wiring or soldering. If the Relay is used with wiring or soldering that is defective, abnormal heating while power is supplied may result in burning.
Before actually using the Relay, perform all possible tests to confirm applicability. Unexpected trouble can occur in actual operation that would not be anticipated in theoretical planning.
Unless otherwise specified, all ratings and performances given in this catalog are for JIS C5442 standard test conditions (temperature: 15 to 35°C, humidity: 25% to 75%, pressure: 86 to 106 kPa). When testing the Relay in the actual application, use the operating environment that will exist in actual applications along with the actual load conditions.
All reference data provided in this catalog are from measurement samples taken from production lines and represented in graph form. Actual values will depend on the application.
All ratings and performances given in this catalog are from independent tests. Values will vary for different combinations of ratings and performances.
