Multilin 469 Motor Management Relay ... - GE Digital Energy

3.1.6 DeviceNet Connection
CHAPTER 3: INSTALLATION
If using the 469 DeviceNet option (Refer to GEK-106491C: 469 Communications Guide),
ensure that the network cable is disconnected from the rear terminal block before
removing the unit out of the case to prevent any damage to the connector.
The unit may also be removed from the case with the network cable connector still
attached to the rear terminal block provided that there is at least 16" of network cable
available when removing the unit out of the case. This extra length will allow the network
cable to be disconnected from the terminal block from the front of the switchgear panel.
Once disconnected, the cable can be left hanging safely outside the case for re-inserting
the unit back into the case.
The unit may then be re-inserted by first connecting the network cable to the units' rear
terminal block (see step 3 of Unit Withdrawal and Insertion on page 3–5).
Ensure that the network cable does not get caught inside the case while sliding in the
unit. This may interfere with proper insertion to the case terminal blocks and damage
the cable.
The DeviceNet port has the following characteristics:
• Connector type: 5-pin Phoenix connector
• Baud rate: 125K, 250K or 500K baud
• Protocol: DeviceNet
The following ports available simultaneously:
• RS232, 2 × RS485/422 with no DeviceNet option
• RS232, 1 × RS485/422 with DeviceNet option
The DeviceNet configuration is shown in the following table:
