2. Installation.
2.1 Requirements.
The power supply unit should be mounted by a qualified installer, holding relevant permits and licenses
(applicable and required for a given country) for 230V/AC and low-voltage installations. The unit should be
mounted in confined spaces, in accordance with the 2nd environmental class, with normal relative humidity
(RH=90% maximum, no condensation) and temperature range from -
10°C up to +40°C. The power supply should
operate in a vertical position in order to provide free and convectional air flow through ventilating holes of the
enclosure.
The power supply load balance should be done before installation. During normal operation, the total
current of the receivers should be below I=8x1A@30V DC.
The power supply is designed for a continuous operation and is not equipped with a power-switch.
Therefore, an appropriate overload protection in the power supply circuit should be provided. Moreover, the user should
be informed how to disconnect the power supply unit from the mains supply (usually by assigning an appropriate fuse in
the fuse box). The electrical system shall be made in accordance with applicable standards and regulations.
2.2 Installation procedure.
1. Before installation, make sure that the voltage in the 230V power-supply circuit is cut off.
2. Mount the PSU in a selected location and lead the connection cables.
3. Connect the power cables (230V AC) to the L-N terminals of the PSU. Connect the ground wire to the terminal
marked with the PE symbol (power supply module connector). Use a three-core cable (with a yellow and green PE
protection wire) to make the connection. The power cables should be connected to the appropriate terminals on the
connection board through the bushing.
The shock protection circuit shall be done with a particular care: the yellow and green wire coat
of the power cable should be connected to the terminal marked with the PE symbol.
Operation of the PSU without the properly made and fully operational shock protection circuit is
UNACCEPTABLE! It can cause damage to the equipment or an electric shock.
