Precautions for Correct Use Installation Orientation There is no specified installation orientation. About the Built-in Diodes* The diodes that are built into the Relays are designed to absorb reverse voltage from the Relay s coil. If a large surge in voltage is applied to the diode from an external source, the element will be destroyed. If there is the possibility of large voltage surges that could be applied to the elements from an external source, take any necessary surge absorption measures. * The MK Series does not have any models with a built-in CR circuit. 7
