3 OPERATION OF SEVERAL APPLIANCES CONNECTED TO EACH ONE
When several KERS recovery units are installed in a single room, it is necessary to synchronize their operation so
as not to put the environment under pressure or vacuum. The devices must be connected in series with each
other (see chapter: electrical connections), so that when half of them work in extraction (phase 1), the other half
works in supply (phase 2).
With the series connection, a single remote control, which operates on the first device, is sufficient to manage all
the KERS installed. Appliances operating in different rooms can also be connected in series, provided that they
have similar needs to each other and can be controlled by the same user terminal.
The maximum number of KERS that can be connected in series with each other, is of up to ten pieces.
4 ELECTRICAL CIRCUITS
4.1 ELECTRICAL EQUIPMENT
The electrical panel is made and wired in accordance with the Low Voltage and Electromagnetic Compatibility
regulations.
The fans, equipped with low consumption reversible EC motors, adjustable between 1.4 W and 7.3 W, are
extremely quiet (22-29db). Once the fan has been installed in the suitably prepared opening (see paragraph
9.4), connect an electric power socket (220 W with 50 Hz).
4.2 WIRING DIAGRAMS
4.2.1 CONNECTION OF A SINGLE UNIT
Grounding is mandatory. The installer must provide for the connection of the earth cable.
The unit is built to work with AC 230 V / 50Hz. To facilitate the connection work, KERS is supplied with a
wired cable and plug, connected on the “INPUT” terminal board on the L = line and N = neutral terminals. The
earth is connected to the special tab, as shown in the figure.
