Connecting the Communications Connections for communications using the modem or Ethernet are described
in this section.
Connecting the Phone Line
If the modem reporting option is being used, an analog telephone patch cable
and a splitter may be required to connect the customer phone line to the
PowerLogic EM4800 meter.
1. Connect the patch cable between the termination block of the phone
line and the PowerLogic EM4800 meter.
2. Route the cable through the slot in the PowerLogic EM4800 meter
enclosure.
3. See the PowerLogic EM4800 meter Configuration Guide for
instructions on how to program the meter for dial-out operation before
performing a manual configuration test.
Connecting the Ethernet Cable
If the Ethernet port is used to report data, an RJ45 patch cable is required to
connect the Ethernet port to the local Ethernet network.
1. Route the cable through the slot in the PowerLogic EM4800 meter
enclosure.
2. If the local network automatically assigns IP addresses through a
DHCP server, the PowerLogic EM4800 meter will be able to report
using its factory default IP settings. If the local network is configured for
static IP addresses, refer to the PowerLogic EM4800 meter
Configuration Guide for instructions on how to configure default static
IP addresses.
Start-Up Sequence Use the following procedure to start up the PowerLogic EM4800 meter.
1. Ensure that all CT and sense voltage wiring is securely installed.
2. Remove all tools from the work area.
3. Re-install all cover plates and equipment covers.
4. Power up the meter. The LCD on the front panel of the meter indicates
the operating status of the unit as follows:
a. Initial power up message “PowerLogic EM48xx”
b. After the internal configuration is complete, the display shows
default information for the first meter.
Manually Testing Communications
This procedure clears the meter memory, manually tests the
communications from the PowerLogic EM4800 meter, and updates the
meter clock. To force the meter to send data, follow these steps:
1. Press and hold the Display button for 5 to 7 seconds until the
diagnostics mode is displayed, then release.
2. If communicating via Ethernet, press the Display button until "Local IP
Address" appears on the display.
a. If the IP address is 169.254.0.10, the meter has not found a
DHCP server. As a result, the meter will use its default IP
configuration and may not be able to report. See the PowerLogic
EM4800 meter Configuration Guide for instructions on how to
program default IP addresses.
