Secure website indicator
A secure website displays a visible indicator such as a lock icon on the web browser.
The web address prefix https:// also indicates that the website is secure.
Web browsers typically prompt or display a message to warn you if a website you are trying to
access is not secure. For https connections, this indicates that the website’s SSL certificate is not
configured properly or is missing.
Default SSL certificate and webpages security
The meter web server protocol is factory-set to HTTPS with HTTP Redirect.
The meter ships from the factory with a self-signed certificate installed and is set to use HTTPS
protocol when accessing the webpages. Because the SSL certificate is self-signed and not signed
by a trusted Certificate Authority (CA), almost all browsers will flag the webpages as unsafe.
•
If your meter is accessible only inside a secure network, you can add a security exception to
override how the browser identifies the webpages.
•
If your meter is outside a secure network, you can install an SSL certificate issued by a CA.
Uploading a custom SSL certificate
You can upload a custom SSL certificate through the meter webpages.
Your meter supports .pem certificate file formats.
To upload a custom SSLcertificate:
1. Use a web browser to log in to your meter.
2. Navigate to Setup > HTTPS.
3. Click Upload certificate.
4. Browse to the custom certificate, select it, then click Open.
