Safety Precautions for All Relays

Precautions for Safe Use

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.

Relay Application

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.
