Firmware upgrade using FTP server

NOTE: To know the applicable firmware upgrade method for your meter model with firmware version, refer to table Meter models, firmware versions and firmware upgrade methods.

NOTE: Refer to Restoration of temporarily disabled configuration settings in webpages to know availability of these features on your meter model.
NOTE: The firmware upgrade process for PM5561 / PM5661 / PM5761 meter models cannot be performed when MID/MIR lock is enabled. You need to remove the MID/MIR lock using the meter display (Refer to Locking or unlocking the PM5561 / PM5661 / PM5761 ) to perform the firmware upgrade process.

You can upgrade the meter’s firmware, language files, webpages and Ethernet communications card using the meter’s internal FTP server.

Your meter, Ethernet card and accessories do not operate normally during firmware upgrade, and your meter’s digital outputs may change state during a firmware upgrade.

  • Do not use this device for critical control or protection applications where human or equipment safety relies on the operation of the control circuit.
  • Do not turn off power to the meter while the firmware upgrade is in progress.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

This example walks through upgrading your meter using Windows Explorer to access the meter’s FTP server. You can also use other FTP clients, such as FileZilla.

  1. Open Windows Explorer and connect to your meter by entering ftp:\\<meter IP address> replacing <meter IP address> with the IP address of the meter you want to upgrade.
  2. Enter a Product Master Username and Password when prompted.

    The FTP server appears, containing the folders fw and www.

  3. Open another instance of Windows Explorer and navigate to the location where you saved the firmware upgrade files.
  4. Copy the PM5500StartUpgrade.shtml file and paste it into the www folder on the meter’s FTP server.
  5. Copy the App2.out and PM5xxx_vX.Y.Z.fwa files and paste them into the fw folder on the meter’s FTP server.
    NOTE: If a file with the same name already exists on the meter, you are prompted to confirm whether or not you want to replace that file. Click Yes (to replace that one file) or Yes to All (to replace all files).
    NOTE: If you have added a large number of custom files (such as webpages) to the meter’s FTP server, there may not be enough memory on the meter’s Ethernet communications card to paste the files, and you may receive an error when you try to paste the files. You may need to temporarily move some of these custom files before proceeding.
  6. Exit Windows Explorer after the file copying is complete.
  7. Open your browser and enter http://<meter IP address>/PM5500StartUpgrade.shtml to trigger the upgrade, where <meter IP address> is replaced with your meter’s IP address.

    Enter your login credentials when prompted.

    NOTE: Accessing this webpage restarts the meter’s Ethernet communications card, which initiates the upgrade process. It might take a minute or two while the meter’s Ethernet communications card is reset and the upgrade initialized.

    From the PM5500StartUpgrade.shtml page, you are redirected to a firmware upgrade status page where you can view information about the upgrade process.

NOTE: If the status page indicates that one of the upgrade processes failed, restart the upgrade process from the beginning by reconnecting to the meter’s FTP server, recopying the files then following the rest of the procedure.
