WEB SERVER
To access the maintenance Web Server with the factory IP address above, use the following credentials:
Username: admin; Password: admin
N.B.: For the R-KEY-LT-P version it is rst necessary to activate webserver mode
The device is normally in Pronet mode; in Pronet mode the device can be congured only through the Easy Setup 2 software.
In order to access the internal webserver it is necessary to put the device in Webserver mode using the Easy Setup2 or Seneca
Device Discovery software. It is also possible to change the operating mode by pressing the side button following the procedure:
To force webserver mode:
• Keep the “REBOOT / MODE” button pressed until all the LEDs ash quickly
• Release the button
• The device restarts and the PWR and COM LEDs ash slowly to indicate webserver mode
To force Pronet mode:
• Keep the “REBOOT / MODE” button pressed until all the LEDs ash quickly
• Release the button
• The device restarts and the PWR and COM LEDs stop ashing slowly to indicate Pronet mode

ELECTRICAL CONNECTIONS
CAUTION
Switch the module off before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc...).
The device can only be powered by a power supply with a limited energy circuit 40Vdc / 28Vac max in output according
to CAN/CSA-C22.2 No.61010-1-12 / UL Std.No.61010-1 (3rd Edition) chapter 6.3.1/6.3.2 and 9.4 or class 2 according to
CSA 223/UL1310.
Use only copper or copper-coated aluminium or AL-CU or CU-AL conductors
These are open type devices intended for installation in a nal casing/panel that offers mechanical protection and protection
against the spread of re.
POWER SUPPLY RS485 SERIAL PORT RS232 SERIAL PORT
The power supply source must be protected from
any module malfunctions using appropriately-sized
safety fuses.
