TECHNICAL CHARACTERISTICS
MECHANICAL INSTALLATION (fig. 2)
n
Store in a clean and dry environment, do not remove the unit from its packaging until it must be used.
n
The device must be installed in environments pollution grade 2 according to EN-60730-1.
n
The protection degree is IP65 depending on the model, therefore must be mounted in places protected from the rain.
n
Install the device in an upright wall, leaving at least 200 mm of space on its top and bottom to facilitate heat dissipation.
n
The unit will be anchored in the wall using the 4 holes of 7 mm in diameter located on its corners.
HYDRAULIC INSTALLATION (fig. 2)
Before proceeding with hydraulic connection it is essential to install a non-return valve in the pump´s inlet or outlet.
It must be mounted a collector for the communication of the devices water outputs. The inlet must proceed from a common
origin.
For mounting the pressure sensor can be used any outlet G1/4 "at the pipe after the pump outlet.
·
It must be installed an hydropneumatic tank of at least 5 l to avoid problems caused by leakeages in the hydraulic net
·
The device is provided with an automatic system that stops the pump if there is no demand in the installation. If you are in
an installation where the device does not stop the pump when there is no demand, this happens because there are leaks in
the installation (tanks, faucet, check valves...). In these cases it can be used the frequency minimum value like a frequency
stop. (see CONFIGURATION)
·
PROCEDURE: Open a faucet of the installation and set the desired minimum flow. With this flow, visualize in the screen the
frequency at which the pump is rotating. Set the minimum frequency to the frequency displayed on the previous screen.
ELECTRIC CONNECTION (fig. 3, 4)The electrical installation must be performed by qualified personal in
compliance with safety regulations and to regulations of each country.
Before doing manipulations inside the device, it should be disconnected of the electric supply and after
disabling, wait for 2 minutes in order to avoid electrical discharges.
The basic unit is served with power cabling, motor cabling and pressure transmitter cabling. The power cord can be replaced
only by the manufacturer or his accredited representative (Y)
.
Then the cabling is exposed as would be done to address any
eventuality:
n
Use cables type H07RN-F with section enough to the power installed:
2
n
Power supply: s = 4 mm
2
n
Motor supply: s = 1 mm
If is necessary to increase the cable length, outer joint is performed following the guidelines of the regulations applicable to
low voltage installation country and and the section of cable will be sized according to the same criteria
n
Verify if the power supply is 230V. Dismount the cover of the electronic circuit and carry out the connections according to the
indications located on the connection strip base.
n
Do the power supply connection (being sure there is a good earth connection):
L1 N .
Do the connection
by mean of
magnetothermic switch in OFF mode.
n
The earth conductor must be longer than the others. It will be the first one to be mounted during the assembly and the last
one The earth conductor must be longer than the others. It will be the first one to be mounted during the assembly and the last
one to disconnect during disassembling.
n
Do the pump connection ( fig. 4).
n
Normally the device is served with the pressure transmitter connected with cable length of 1.5 m. Otherwise, connect the
pressure transmitter (fig. 3). H03VV 2x0, 5mm cable is used.
If is necessary to increase the cable length, outer joint is performed following the guidelines of the regulations applicable to
low voltage installation country - the cable length should not exceed 15 m.
n
Min. level control (optional). There is an input for stopping the pump as soon as is disconnected the external switch of
minimum level. See fig.3
WARNING!. Wrong connections could spoil the electronic circuit. The manufacturer declines all responsability in
damages caused by wrong connection.
