Safety Precautions
Applicable Sockets
Use only combinations of OMRON Relays and Sockets.
Application Environment for Hermetically Sealed
Relays
Humid environments can cause insulation problems, which may result in short-
circuiting or unintended operation.
Solution
Do not use these Relays in any environment where the Relay will come into
contact with water vapor, condensation, or water droplets. This can reduce the
surface tension of the insulating beads and cause short-circuiting or unintended
operation due to poor insulation.
Relay Replacement
To replace the Relay, turn OFF the power supply to the load and Relay coil
sides to prevent unintended operation and possible electrical shock.

• Design with sufficient dielectric separation between
terminals eliminates the need of any insulating sheet.
