FLEX 5000 EtherNet/IP Adapters with RJ45 Ports
Connect Power to the Adapter
Before you connect power to a FLEX 5000 EtherNet/IP adapter, complete the following tasks:
• Read
Power Considerations on page 7
.
• Confirm that the external power supply that supplies module power is adequately sized all installed modules. For more information, see
Power Considerations on page 7
.
• Install the Power RTB on the adapter before you connect power to the adapter.
Install the Power RTB
1. If the Power RTB lever is pushed in, pull the lever until it fully extends and clicks.
2. Insert the Power RTB into the RTB slot as shown in the graphic and press it until it clicks.
3. Press the lever until it clicks.
The Power RTB is locked into the adapter.
Connect Power to the Power RTB
Before you connect an external power source to the Power RTB terminals, make sure that the power source is properly sized. For example, if the total
module power current draw, including current inrush requirements, is 4 A, you can use a power supply that is limited to 4 A.
1. Verify that the external power supply is not powered.
WARNING:
If you connect or disconnect the removable terminal block (RTB) with power applied, an electric arc can occur. This could cause an explosion in
hazardous location installations.
The removable terminal block (RTB) does not support “removal and insertion under power” (RIUP) capability. Do not connect or disconnect the removable
terminal block (RTB) while power is applied. Be sure that power is removed before proceeding.
IMPORTANT
Your application can require a power control device, for example, a switch, between the external 24V DC power source and the adapter to control when the
module is powered. If so, you must install the power control device at the VDC+ terminal on the removable terminal block.
If you install the power control device at the VDC- terminal, the adapter can fail to power up or power down properly.
