an example of wiring to a Modbus/TCP network.
Figure 2.4 Connecting the Ethernet Cable to the Network
4. Route the other end of the Ethernet cable through the bottom of the
PowerFlex drive ( Figure 2.3 ) and insert its Ethernet cable plug into the
mating adapter receptacle.
Applying Power
Install the drive cover or close the drive door, and apply power to the drive.
The adapter receives its power from the connected drive. When you apply
power to the adapter for the first time, its topmost “PORT” status indicator
should be steady green or flashing green after an initialization. If it is red,
there is a problem. Refer to
Chapter 5 , Troubleshooting .
Start-Up Status Indications
After power has been applied, the status indicators for the drive and
communications adapter can be viewed on the front of the drive
(
Figure 2.5 ). Possible start-up status indications are shown in Table 2.A .

ATTENTION: Risk of injury or death exists. The PowerFlex
drive may contain high voltages that can cause injury or death.
Remove power from the drive, and then verify power has been
discharged before installing or removing the adapter.
