Electrical safety

DANGER

Electrical hazard
The voltages used in the Solar Tracking Control System can cause electrical shock or burns and could be lethal. For this reason, precautions must always be taken to the extreme when working with, or adjacent to, the control system equipment. Specific warnings are given throughout this user manual. The user who works with the device must always agree with this manual.

System assembly warning
The Control System is intended as an ensemble of components for professional incorporation into a complete solar tracking installation.
Close attention to the electrical installation and the system design is required to avoid hazards either in nominal operation or in the event of equipment malfunction.

NOTICE

Technical tasks
Installation, commissioning/start-up, and maintenance must be carried out by personnel with the necessary training and expertise. They must read this safety information and this manual carefully.

Installation risks
Regarding safety measures during the installation of the equipment:

• If a mechanical or electrical component is damaged, do not use the product and contact your supplier.
• If the installation instructions are not followed correctly, some problems might arise, such as damage to the unit or physical harm.
• The work tools used to install the device should be approved for the job considering the voltage in the system.
• Once the installation has been carried out, the installed units and the cables should not be moved.
• The power cables from the panel to the device cannot be wrongly connected, the connectors are differentiated.
• Use appropriate and well-maintained tools.
• Inspect all equipment regularly for damage. In case the tools are not in good condition, replace them.
• Use personal protective equipment.
• Monitor weather conditions to avoid working during adverse weather.

Radio Frequency (RF)
In relation to Safety due to the possibility of radio frequency (RF) interference, you must follow all the special regulations that may apply regarding the use of radio equipment. Follow the safety advice given below.

NOTICE

Radio frequency hazard
Operating your device close to other electronic equipment may cause interference if the equipment is inadequately protected. Observe any warning signs and manufacturers’ recommendations.

Interference with pacemakers and other medical devices

Potential interference
Radio frequency energy (RF) from cellular devices can interact with some electronic devices. This is electromagnetic interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted cardiac pacemakers and defibrillators from cellular devices. This test method is part of the Association for the Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that cardiac pacemakers and defibrillators are safe from cellular device EMI.
The FDA continues to monitor cellular devices for interactions with other medical devices. If a harmful interference occurs, the FDA will assess the interference and will work to resolve the problem.

Precautions for pacemaker wearers
Based on the current research, devices do not pose a significant health problem for most pacemaker users. However, people with pacemakers may want to take simple precautions to be sure that their device does not cause a problem. If EMI occurs, a pacemaker could be affected in one of the following three ways:

• Stop the pacemaker from delivering the stimulating pulses that regulate the heart rhythm.
• Cause the pacemaker to deliver the pulses irregularly.
• Cause the pacemaker to ignore the heart own rhythm and deliver pulses at a fixed rate.

WARNING
Radio frequency hazard
Keep the device on the opposite side of the pacemaker to add extra distance between the pacemaker and the device. Avoid placing a turned-on device next to the pacemaker.

General description

DBox 5 is the next controller generation by PVH, following DBox 4.0. It has been designed to control and monitor the movement of the structure, improving solar tracking and power generation.

NOTICE

DBox 5 information
Refer to DBox 5 data sheet for information on DBox 5 and DBox 5 peripheral devices technical data.

Physical features
DBox consists of an IP67 electric cabinet prepared for LoRa communications. It has a pressure membrane that ensures the safety of the components inside the enclosure. DBox 5 design allows to reduce both installation and commissioning times.

Externally, there are two main components: the front panel and the connectors panel.

The DBox can operate as a tracker control unit or as a meteorological control unit depending on its commissioning configuration and Location on the structure.

Horizontally oriented Front Panel

• Installed on torque tube.
• DBox functional configuration: tracker controller.

Vertically oriented Front Panel:

• Installed on the tower.
• DBox functional configuration: meteorological box.

NOTICE
Dbox 5 appearance
The color of DBox 5 casing may vary.

Labelling
DBox 5 label format:

Front panel
The front panel can be vertically or horizontally oriented depending on the DBox functional configuration and location.
It is situated on the cover of the DBox. It is composed of:

1. Two capacitive buttons to move the structure (up and down).

2. An NFC tag to connect with the Control App which is used as an interface by the user, to control and commission the device by transferring parameters and commands.
   NOTICE
   PVH app info
   Refer to PVH App user manual for information related to the use of the app.

3. LED indicators which inform when:

   • An error has occurred.
   • Nominal operation is taking place.
   • The motor is moving.
   • DBox is communicating via LoRa.

NOTICE
LED indicators behavior
The LED indicators behavior is yet to be defined.

Connectors panel
The Connectors Panel of the □Box has 3 cable glands for the different cables used to connect the system and a stop button in case of emergency (Red button).

Connections

• In connector l a peripheral device such as an anemometer can be connected through a female connector.
• In connector 2, the □Box must be connected through a female connector to the motor placed on the structure to move the structure.
• In connector 3, regardless the □Box 5 version, the power is supplied though a male connector.
