This extra length will allowthe network cable to be disconnected from the terminal block from the front of theswitchgear panel. Once disconnected, the cable can be left hanging safely outsidethe 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 3–4).Ensure that the network cable does not get caught inside the case whilesliding in the unit. This may interfere with proper insertion to the caseterminal 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: DeviceNetThe following ports available simultaneously:• RS232, 2 × RS485/422 with no DeviceNet option• RS232, 1 × RS485/422 with DeviceNet optionThe DeviceNet configuration is shown in the following table:Pin Signal Description1 V– Negative supply voltage2 CAN_L CAN_L bus line3 SHIELD Cable shield4 CAN_H CAN_H bus line5 V+ Positive supply voltageCAUTION
