Electrical Installation; Cabling And Wiring; Installation Recommendations For The Control Unit - S&P PULSE 160 Manual De Instrucciones

4. ELECTRICAL INSTALLATION

PULSE 160 units can only be operated in con-
junction with a control unit, purchasable separa-
tely. Up to four PULSE 160 units can be connected
to one control unit. Where more than four PUL-
SE 160 units are needed, additional independent
groups managed by further control units will
be needed. The control unit can be installed an-
ywhere. 3-pole cables (preferably LiYY cables with
cross-sections between 0,25mm² and 0,75mm²)
are required. To ensure adequate power, the cable
length between the control unit and fan unit must
not exceed 100 m.

4.1. INSTALLATION RECOMMENDATIONS FOR
THE CONTROL UNIT
Install the control unit at standard wall height (105
cm distance to fl oor) in a deep pattress box. The
power supply unit can also be installed in the box.
The frame must be correctly positioned in the pat-
tress box to allow the control panel to be clicked in.
Please make sure that the bottom side of the con-
trol panel is unobstructed and that the opening for
the humidity sensor is not blocked.
The installation is to be done in such
a way that the 12V output cable and
the 230V input cable are not on the
same side of the power supply (ins-
tall the 230V cable underneath).
Instead of a power supply unit in a pattress box, a
DIN rail power supply may be used. However, such
a power supply requires a further cable duct for
the cable to the fuse box.

4.2. CABLING AND WIRING

All electrical work must be performed by a quali-
fi ed electrician. Make sure that all wiring is done
correctly.

The starting direction of the fan is defi ned by the
connector on the PCB (IN = Start direction supply
air, OUT = Start direction exhaust air). The starting
direction is also used in full-blast mode. To con-
nect the control unit to the fan units, a 3-pin plug
must be connected to the cable. The plug must be
wired as shown below.
