2. Installation.
2.1 Requirements
The buffer PSUmodule 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 confined spaces, in accordance with the 2nd environmental class, with normal relative
humidity (RH=90% maximum, without condensation) and temperature from -10°C to +40°C. The PSU module sh all
work in a vertical position that guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
The PSU module provides voltage of 27,6 V DC with current capacity:
1. Output current 1A (without a battery)
2. Output current 0,8A + 0,2A battery charge
3. Output current 0,5A + 0,5A battery charge
Total current of the rec battery: 1A max.
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 device should be installed in the metallic enclosure, distribution board (ICT cabinet) equipped with a DIN TH35
rail (35 mm wide). In order to meet the UE requirements, the rules concerning: supply, development and shielding
