4. Use a multimeter to check that the CU320-2 PN really is in a no-voltage condition.
5. If it has not already been done, label all connectors and cables that lead to the module now.
Only then, can it be ensured that the cables are not interchanged.
6. Withdraw the electronics power supply X124.
7. Withdraw the DRIVE-CLiQ cables X100 - X103.
8. Withdraw the Profinet cable.
9. Withdraw all other cables, if available.
10.Remove the protective conductor connection of the CU320-2 PN.
11.Release the screws attaching the CU320-2 PN to the mounting plate.
12.Remove the CompactFlash card.

This is how you install the CU320-2 PN
Installing
Procedure:
1. Screw the new CU320-2 PN onto the mounting plate.
2. Reconnect the protective conductor connection of the CU320-2 PN.
3. First insert the PROFINET cable that was previously withdrawn.
4. Insert the DRIVE-CLiQ cables that were previously withdrawn into sockets X100-X103.
5. Insert all other cables, if available.
6. Reconnect the electronics power supply X124.
7. Now check that all of the cables have been reconnected.
8. Insert the CompactFlash card.
9. Close the cover of the CU320-2 PN.
10.Close the cabinet and switch-on the system again.

CU310-2 PN status displays
Module status displays
Four LEDs at the front of the CU310-2 PN provide information about the state of the module.
They indicate the states when powering up and in operation:
● If an error occurs, the power-up is terminated and the LEDs indicate the cause of the error.
● At the end of an error-free power-up, all LEDs are switched off briefly.
● After power-up, the LEDs are controlled via the loaded software.
