How to ensure the IEC power cable plug is securely connected to the IEC socket?

Issue: How to ensure the IEC power cable plug is securely connected to the IEC socket?

Product Line: UPS models with IEC type input and output connections

Cause: IEC power cable plugs require a firm insertion into the IEC socket to ensure the connection is secure.

Resolution:

IEC connectors typically provide tactile feedback to indicate when the connection is fully engaged.
It is not sufficient for the plug to simply come in loose contact with the socket. In this state, the connection will be loose, and the plug can wiggle. Refer to the image on the left.
After the plug is in contact with the socket, and additional firm push is required to secure the connection and ensure it is fully engaged. In this state, the plug can no longer wiggle. Refer to the image on the right.

The state of the connection can be determined by physical inspection. If the plug can wiggle in the socket and the shroud of the plug is hanging out more than 1-2 mm from the socket, it is likely not fully and securely connected.
