J FORCIBLY GUIDED CONTACTS When NO contacts are welded, the coil will be non-energized so all NC contacts will maintain a distance between the contacts of 0.5 mm minimum. Likewise if NC contacts are welded, the coil will be energized so all contacts will maintain a distance between each other of 0.5 mm minimum. Caution Do not touch the terminal area of the Relays or the socket ter- minal area (charged area) while power is ON. Electric shock will result. J SAFETY RELAYS A Safety Relay is a relay with which a safety circuit can be configured. For common precautions when using and handling relays, consult Omron. J CONTACTS The coil terminals have polarity (positive and negative).Operation is not possible if these are connected in reverse.
