2. Installation.
2.1 Requirements.
The buffer PSU shall be mounted by a qualified installer with appropriate permissions and qualifications for
230V/AC installations and low-voltage installations (required and necessary for a given country). The device shall
be mounted in confined spaces, according to the environment class II, with normal air humidity (RH=90% max.
without condensation) and the temperature from -10°C to +40°C. The PSU shall work in a vertical positi on that
guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
Before installation, prepare a PSU load balance.
1. Output current 5A + 0,5A battery charge
2. Output current 3,5A + 2A battery charge
Total device c battery: 5,5A max.
As the PSU 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 (usually through assigning an appropriate fuse in the fuse-box). The
electrical system shall follow valid standards and regulations.
