2. Installation.
2.1. Requirements.
The buffer 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 and low-voltage installations. The unit should be mounted in
confined spaces, in accordance with the II-nd environmental class, with normal relative humidity (RH=90% maximum,
without condensing) and temperature from -10°C to +40°C.
The unit should be mounted in a metal enclosure (cabinet) in a vertical position so as to ensure free, convection
air flow through the vents.
In order to meet the EU requirements, follow the guidelines on: power supply, enclosures and shielding:
- according to application. The module requires 20-22V AC power supply with galvanic. (transformer) isolation.
1. Output current 2A + 0,2A battery charge
2. Output current 1,7A + 0,5A battery charge
Total device current + battery: 2,2A 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.
