2. Installation.
2.1. Requirements.
PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required for a
given country) for 230 V in and low-voltage installations. Unit should be mounted in confined spaces, in accordance, with
normal relative humidity (RH=90% maximum, without condensing) and temperature from -
10°C to +40°C. The PSU shall
work in a vertical position that guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
As power supply is designed for a continuous operation and is not equipped with a power-switch, therefore, an
appropriate overload protection in power supply circuit should be provided. 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.
2.2. Installation procedure.
Before installation, cut off voltage in 230 V power-supply circuit. To switch power off, use an
external switch, in which distance between contacts of all poles in disconnection state is not less
than 3mm.
It is required to install an installation switch with a nominal current of 6 A in power supply circuits outside
power supply unit.
