Is the XB7 Harmony LED indication lamp protected against reverse protection or do we need to provide diode in reverse bias to ensure the same?

The XB7 LED indication lamp does not require external diode for protection. If the 24VDC ( + ) & ( - ) connections are reversed in connection, the LED will not glow, however it will glow after correcting the connection. Reversing the connection will not damage the LED lamp.
