INSTALLATION INSTRUCTIONS
SAFETY
In order to maintain these conditions and ensure safe use, the user must follow indications and markings contained in the following instructions.
Warning: Failure to follow these instructions below can result in death.
• Upon receipt of the instrument, before proceeding with the installation, check that it is intact and has not been damaged during
transport.
• Check that the operating voltage and the mains voltage coincide and then proceed with the installation.
• The instrument power supply must not be grounded.
• The instrument does not have a fuse to protect the power supply, so it must be protected by the installer.
• Maintenance and/or repair operations must be carried out only by qualied and authorized personnel.
• If you suspect that the tool is no longer secure, take it out of service and make sure it is not used inadvertently.
• Dangerous voltages can be present on voltage and current transformers. Follow standard safety precautions before performing
any installation or service activity.
• The instrument and its connections must be properly protected.
• The instrument must be installed following all local regulations.
Precautions: Failure to follow the instructions below can cause persistent damage to the instrument.
• The digital outputs and inputs are low voltage and cannot be connected to external power sources.

POSSIBLE GPIO CONFIGURATIONS
GPIO 1 IN - GPIO 2 IN GPIO 1 IN - GPIO 2 OUT
GPIO 1 OUT - GPIO 2 IN GPIO 1 OUT - GPIO 2 OUT
The GPIOs can be congured both as digital inputs and as digital outputs, below are the conguration examples based on how the two GPIOs are set.
The front cover of the device can be pressed like a button. By pressing, it is possible to activate customizable and pre-programmed logics through
the OVERBOARD, which depending on user’s needs can also affect GPIOs, other OVER devices in the same BUS network or send an alert via the
OVERBOARD.
Attention. For programming, it is necessary to connect the device via EDS BUS to the OBox and perform the procedure via a local web interface to the
OBox or via OVER’s Cloud portal.

FRONT PANEL
On the front cover of the device there are 16 LEDs placed along its
circumference, distributed, as shown in the gure, in the area highlighted
in blue. The LEDs light up in different ways to communicate the different
states of the device. Below is the list of possible types of lighting and their
associated meanings.
Quick ashing: As soon as it is connected to the power supply, the
LEDs will ash rapidly to conrm correct power supply.
Continuous power on: The LEDs will light up once at a time,gradually
and in a clockwise rotation indicating that the device is not calibrated.
When this happens, please contact support.
Rotation: The LED strip lights up in a clockwise circular movement to
indicate that the device has entered the programming mode.
Double ash: This indicates that the device has been pressed.
