c CAUTION:

For lightning protection, the AC power should be led through an external lightning device into the switch.

Make sure the power switch on the PSU is at OFF position before connecting the power cord.

On the front panel of AC PSU, there is a plug-retention clamp.

Take the following steps to connect the AC power cord (coming with the switch) to the Switch 8807/Switch 8810/Switch 8814:

Step 1: Turn the clamp at the left of the PSU front panel to the right.

Step 2: Insert the plug at one end of the AC power cord into the socket on the PSU.

Step 3: Turn the clamp to the left until it grips the plug.

Step 4: Insert the other end of the power cord into an external power socket.
