If using a modem, these items are also required:
• phone or butt set to test the phone line
• RJ11 junction box
• RJ11 splitter to tap into the existing junction box
• RJ11 patch cable
• xDSL filter if required (many businesses have their internet access on
the same line as the fax)
Site Planning 1. Determine the number of PowerLogic EM4800 series meters to be
installed and ensure adequate space. For clearances, see Figure 4 on
page 10.
2. Determine the number of analog phone lines or Ethernet drops
required, and ensure they are installed before installing the PowerLogic
EM4833, EM4880 and EM4805 meters. The recommended maximum
number of PowerLogic meters per phone line is 50.
3. Determine the number and types of meters or monitors required
(single-phase, network, or three-phase).
4. Determine the model number and correct sense voltage based on the
voltage label on the top right side of the unit.
Access to Power and Lighting
The installation site must be supplied with access to the main electrical panel
and any sub-panels. Portable or permanent lighting must be available to
provide the installers with a clear view of the equipment and of the installation
environment. Each installation may vary depending on physical site
restrictions.
