Power supply (24V DC) for EP010 comes from the FBP.
Connected Modbus device, however, must be independently powered.
Protective Earth (PE) must be connected to earth.

Replacement of a defective EP010
A defective EP010 can be replaced without any problems. After disconnecting
Modbus cables and the FieldBusPlug, the EP010 can be dismounted and replaced.

Start-up
At power up or after a reset, beginning with all the LEDs switched OFF, a diagnostic
process starts and the following sequence is performed:
Table 3. Start-up LEDs sequence
Then all LEDs stay ON for about 500 ms. After this time:
1. all the LEDs are switched OFF
2. the WD LED flashes a number of times depending on the device that can be
connected on the Modbus Port
3. the EP010 enters in Run state.
The total start-up time is less than 3 [s].
5
Run State
The table reports the normal behaviour of LEDs in this state.
(1) If the FBP is disconnected, the EP010 is powered off.
After a failure has been detected and signalled, the FAULT LED continues flashing until:
1. the FBP is communicating with the EP010 (and then the EP010 is communicating with
the device using the Modbus port) and the fault is removed OR
2. the EP010 is power off (i.e. the FBP is disconnected) or reset.

Installation and maintenance have to be performed according to the technical
rules, codes and relevant standards e.g. EN 60204 part 1 by skilled
electricians only.
Remember that the address associated to the device via the EP010 is stored
into the FBP. Therefore, after installation, the new EP010 takes on the same
address as the replaced one.
