4.0 PRELIMINARY INSTRUCTIONS FOR USE
The module is designed to be installed on DIN 46277 rail (fig.1) in vertical position.
No operation on the module is allowed while it is power on.
It is forbidden to install the module near heat-emitting devices
It is reccomended that the use and installation operations are performed by an
electrical-skilled technician
5.0 INSTALLATION
To install/remove the module on/from DIN 46277 rail, execute the following operations
(Fig.1a and Fig.1b
5.1 Installation on/removal from DIN 46277 rail
INSTALLATION
1)Pull the four latchs (placed in the back-
side panel) outwards;
2) insert the module in a DIN rail free slot;
3) make sure that the IDC10-connector pins
are inserted on the slot correctly;
4) press the four latchs inwards.
REMOVAL
1) Pull the four latchs (placed in the back-
side panel) outwards, using a screwdriver;
2) pull out the module gently.
It’s important to insert the pins on the slot correctly because IDC10-connector is polarized;
this connection is facilitied by use of a female/male insertion between IDC10 connector and
DIN rail slot (Fig 1c and Fig 1d).

6.2 USB
USB port with mini-B plug-in for a easy PC
connection.
This port allows to use the Easy setup
configuration software to configure
the module or update firmware (free
download from www.seneca.it).
FAIL MODE ENABLED (see software Easy)
If there is no Modbus communication through all ports (port 1 RTU, port 2 RTU) for a time
greater than «timeout to start fail», it follows that:
- relay outputs switch, in the state configured on software Easy
- the LED PWR starts to blink, to signal the fail condition.
In this condition, if Modbus communication returns through at least one of the two ports,
the outputs remain at the previous state and the LED PWR returns in the status of
constant light.

(*) For two RTU ports, it is possible to assign a baudrate and an address different from
each other using Easy setup software. In this case, all switch 1..8 must be in OFF.
Unchangeable parameters from dip-switch: DATA: 8 bit, PARITY NONE, 1 STOP bit
For both RS485 ports, default parameters are: 38400 baud, 8N1
(from EEPROM).
IMPORTANT: the dip-switch SW2 placed at the right of the switch number 8
must be always in position ON!
