Chart 1. Allowable output current from the power supply depending on ambient temperature.
2. Installation.
2.1 Requirements.
The buffer power supply shall be mounted by the qualified installer having appropriate (required and
necessary for a given country) permissions and qualifications for connecting (operating) 230V/AC installations and
low-voltage installations. The device shall be mounted in closed rooms, according to the environment class II, of
the normal air humidity (RH=90% max. without condensation) and the temperature within the range from -10°C to
+40°C. The power supply shall operate in a vertical position so that free and convectional air flow through
ventilating holes of the casing is guaranteed.
Before installation is started, the balance of the power supply load shall be performed. During the normal
operation, the sum of currents collected by receivers shall not exceed
I=4.0A
.
As the power supply is designed for a continuous operation and is not equipped with a power-switch,
therefore an appropriate overload protection in the power supply circuit shall be guaranteed. Moreover, the user
shall be informed about the method of isolation of the power supply from the power voltage (usually through
assignment and marking of an appropriate fuse in the fuse-box). The electrical system shall be made in
accordance with valid standards and regulations.
2.2 Installation procedure.
1. Before beginning installation, ensure that the power in the 230V AC power supply circuit is
disconnected.
2. The power supply is to be mounted in the selected space and the connection cables attached.
3. Electric power supply cables (~230V AC) should be connected to terminals L-N of the power supply. The
grounding cable should be connected to the terminal indicated by the symbol PE (power supply module connector).
The 3-way cable should be connected (with the yellow-green PE earth terminal) The power supply cables should
be inserted into the proper terminals of the switching board using an insulating bushing.
