◆Please avoid wiring and plugging or unplugging in active status; otherwise, electric shock or circuit
damage may occur;
◆All installations and wirings must be firm and reliable as poor contact may lead to malfunction;
◆In case of applications with serious interferences, shielded cables should be used for input or output
of high-frequency signals, so as to enhance the anti-interference performance of the system.

Safety Warning
User Manual for Digicom HC Series Multi-Screen Processor v
Precautions for Wiring
◆No installation or wiring operation should be performed until all external power supplies are
disconnected, otherwise electric shock or equipment damage may occur;
◆This product is grounded through the earth lead of the power cord. To avoid electric shock, the earth
lead must be connected to the ground. Before connecting the input end or output end of this product,
please ground this product correctly;
◆After completing installation and wiring, please remove foreign objects immediately; Before
connecting the power supply, please close the terminal cover on the product to avoid electric shock.
Precautions for Operation and Maintenance
◆When the power supply is connected, do not touch the terminal; otherwise, electric shock or incorrect
operation may occur;
◆Please clean and tighten the terminal after the power supply is disconnected, as electric shock may
occur when such operations are performed when the power supply is connected;
◆Please perform operations such as the connection or removal of communication signal cables or
extension module or control unit cables after the power supply is disconnected; otherwise, equipment
damage or incorrect operation may occur;
◆Do not disassemble the equipment lest the internal electric components may be damaged;
◆Please read this manual carefully and fully confirm the safety before performing any program
variation, commissioning, starting or stopping operation.

Chapter 4 Installation
Precautions for Installation
1) The onsite installation shall be performed by the trained and qualified technicians. Please turn
to the after-sales service or agent of VTRON for technical instructions before installation. For
the equipment and personal safety, at least two technicians are needed to perform the
installation onsite.
2) When shipped from the factory, the Digicom HC Series Multi-Screen Processor is provided to
the user as a whole unit. All hardware board modules and software program modules of the
Digicom HC Series Multi-Screen Processor are produced in the factory according to strict
production procedures and have undergone a series of tests such as high temperature and
aging tests. Upon installation at the site of the user, the user only needs to connect the Digicom
HC Series Multi-Screen Processor to external equipment.
3) Before installing the Digicom HC Series Multi-Screen Processor, please check whether the
installation environment meets the requirements of Digicom HC Series Multi-Screen Processor
on its operating environment (e.g., temperature, humidity, power supply, grounding system,
etc.), so as to ensure that the equipment can be put into normal operation after installation, and
its service life can be guaranteed.
4) Please use the cables delivered together with the product (including the signal cable, network
cable, and power cable). If the user needs to use his/her own cable, please turn to the
after-sales service department or agent of VTRON for corresponding technical instructions.

Chapter 4 Installation
User Manual for Digicom HC Series Multi-Screen Processor 4-2
4.1 Installation environment
Before installing the Digicom HC Series Multi-Screen Processor, please check whether the installation
environment meets the requirements of Digicom HC Series Multi-Screen Processor on its operating
environment (e.g., temperature, humidity, power supply, grounding system, etc.), so as to ensure that the
equipment can be put into normal operation after installation, and its service life can be guaranteed.
Requirements on temperature and humidity:
Operating temperature: 0 ºC -40 ºC
Relative humidity: 20%-80%, no condensing
Requirements on power supply
The power supply for the Digicom HC Series Multi-Screen Processor shall be 110-240V 50/60 Hz.
Please make sure that such power supply can be provided in the installation environment. In addition, to
ensure the stability of the power supply to the Digicom HC Series Multi-Screen Processor, the power
socket of the Digicom HC Series Multi-Screen Processor must be connected to independent power
plugboard (220V 10A standard plugboard recommended). Do not share power plugboard with other
equipment.
Requirements on grounding:
Therefore, when installing the Digicom HC Series Multi-Screen Processor, you need to fully consider the
grounding measures of the whole system environment, including whether the power supply has the
grounding measure (e.g., adopting the certified three-core power cable and power socket).
Corresponding equipment grounding terminals should be reserved in the on-site system grounding.
When there are insufficient grounding terminals in the system grounding, it’s necessary to increase the
number of equipment grounding terminals by increasing the number of grounding bar. (The resistance
between the on-site reserved system grounding terminals and the protection ground should be lower
than 3 ohms).

Chapter 4 Installation
User Manual for Digicom HC Series Multi-Screen Processor 4-3
Besides, when installing the Digicom HC Series Multi-Screen Processor in the high-rise building, the
equipment shall be connected to the true earth through the dedicated safe grounding system and kept
away from the SPD grounding system of the building. Improper system grounding will have large
negative effect on the signal transmission, which will result in the imaging interferences that cannot be
removed through debugging. For details, please consult VTRON. Please strictly comply with the relevant
instructions and maintain proper grounding during the use of the equipment.
