Grounding ensures safe electrical circumstances and helps avoid potential electromagnetic
interferences and noise. Make sure ground has been connected correctly and securely, in compliance
with current regulations, before switching on the equipment.
The equipment must connect to ground using the screw terminal marked with the earth IEC symbol
and provided in one of the connectors. Make sure that the protective earth conductor is connected
correctly to that ground terminal. Additionally, the equipment makes a chassis ground connection
through the DIN rail, which in turn must relate to the ground.
Make sure to use DIN rail with good conductive properties. It is
recommended to use steel DIN rails. Do not use DIN rails made of plastic or
poor conductor materials. Ensure the DIN rail is not oxidized or corroded or
presents any other defects resulting from improper chassis grounding.
For metallic enclosures it is a highly recommended enclosure that is
connected to ground to avoid potential EMI or noise interferences going into
the equipment.
Failure to ensure a correct ground connection may result in an electrical risk
and cause the equipment to work in an unfavorable operating condition.
See Electrical installation for the wiring details about how to connect the power supply and grounding
on the equipment.
4.6. Batteries and battery charging
The Vigilant has a rechargeable internal lithium-polymer battery as its auxiliary power supply. The
integrated battery recharges automatically when the device is connected to the main DC power
adaptor. The equipment battery is assembled inside, under a cap located in the back of the instrument
and closed by screws. See chapter dedicated to Replacement of internal components to read more
about the battery and its possible replacement.
The Battery is mainly used to properly shut down the system.
The system has been designed for a specific battery model, which also
includes an integrated electrical protection system. In no event should the
battery be replaced with a different model.
Access to the battery for replacement, if necessary, must be carried out by
personnel authorized by the product manufacturer or distributor.
4.7. Transport and storage

5.System Description
5.1. Introduction
Vigilant Online Machinery Supervisor is a state-of-the-art monitoring system whose purpose is to
provide users with the measurements required for assessing the condition of the machinery or
equipment being monitored.
Vigilant is a smart solution for protection, condition monitoring and failure mode identification of
critical machinery. It can work as a standalone system, it does not require a permanent connection to
a computer or software, while still measuring and protecting the equipment, storing data or even
communicating scalar measurements to other systems via Modbus, TCP protocol or API-rest.
It accepts both static and dynamic signals from most kinds of sensors typically used for condition-based
monitoring: vibration, temperature, ultrasound, thermal images, speed, motor current, oil condition
parameters, load, process, etc.
Vigilant is a small size and low consumption hardware device. It integrates a web server application
that provides an interface for users through a web browser, without installing any software. With that
web interface, the user can configure and access all data being measured in the unit, along with all the
types of graphs required for its visualization and analysis (trends, spectrum, waveform, parameter
tables, etc.). It also provides data storage with enough capacity for enabling monitoring of extended
periods. The advantages of this new technology are:
•It eliminates the need for a local server, and therefore its maintenance is also eliminated.
•It can be connected directly to the Internet, so the measurements can be accessed from any
part of the world using a computer or device connected to the Internet and a web browser.
•It is not required to pay for software licenses to access the data.
•Access is not limited to specific operating systems, computers, or devices.
•Obsolescence is avoided by applying automatic updates.
•It is very intuitive, accelerating the learning curve and allowing users to access all the start
functionality.
•Reduce the initial investment by simplifying the monitoring system.
•The system includes 8 analog inputs with simultaneous high-frequency sampling and 4
additional low-frequency sampling analog inputs.
•Vigilant also includes bidirectional communication via Modbus-TCP protocol for its integration
with external systems.

8.Installation
8.1. Mechanical assembly
The Vigilant system was not designed as an “enclosed type” system. That means that it generally
requires to be installed in an external enclosure prepared for the application site’s environmental
conditions.
The unit includes an accessory to be mounted on standard DIN rail (35 mm rail). Using the accessory
installed at the back of the casing, it can be mounted on a DIN rail fastened to the mounting panel of
the enclosure.
The following pictures describes the steps for assembling or removing the Vigilant from the DIN rail.
To install the unit on a DIN rail,
align it with the top edge, press
firmly downwards and push
forward the lower end into
position.
To remove the unit, press
firmly on top downwards, and
pull the lower end away from
the DIN rail.
Vigilant includes a forced ventilation system that regulates its
temperature. However, to guarantee proper air cooling, the enclosure’s
temperature must be kept within the allowable limits (see Specifications).
It must consider the heating caused by all components within the
enclosure, installing a forced ventilation system if required.
Allow some free space around the air input grid and equipment’s fan
output to ensure proper air cooling. To improve heat dissipation, remove
any insulation material close to the unit.

Vigilant User Manual
20/232
Outdoor installations are particularly susceptible to condensation.
This should be avoided by installing the corresponding components
within the enclosure. Direct sunlight and high ambient
temperatures should be avoided. It is recommended to separate the
unit from any external heat source that could cause high
temperatures.
It is the assembler’s responsibility to ensure the environmental
conditions described at the specifications of the unit.
