2. Installation.
2.1 Requirements
The PSU module is to be mounted by a qualified installer, holding relevant permits and licenses (applicable
and required for a given country) for 230V/AC interference and low-voltage installations. The unit should be
mounted in accordance with the 2nd environmental class, with normal relative humidity (RH=90% maximum,
without condensation) and temperature from -10°C to +40°C.
Before mounting the PSU module, perform a load balance. During normal operation, total current drawn by
the receivers cannot exceed the maximum parameters.
As the PSU module is designed for a continuous operation and is not equipped with a power-switch,
therefore an appropriate overload protection shall be guaranteed in the power supply circuit. Moreover, the user
shall be informed about the method of unplugging (most frequently through separating and assigning an
appropriate fuse in the fuse-box). The electrical system shall follow valid standards and regulations.
The PSU module requires AC or DC power supply with galvanic insolation (II insolation class), short-circuit
and overload protections. The power of the source can be calculated with the following formula:
