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 not exceed I=2A. The maximum battery charging current is 0,2A. The total
current of the receivers + battery is max. 2,2A.
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
The unit should be mounted in a metallic enclosure (telecommunication cabinet) fitted with TH35 DIN rail (35 mm
width); in order to meet the LVD and EMC requirements, the rules concerning power supply, building-in and
shielding should be followed accordingly.
