5.5 ELECTRICAL CONNECTION OF THE EQUIPMENT
·
The installation must be carried out by qualified personnel.
·
Cables complying to the section with the current directives must be installed
preventing heating and a voltage drop higher than that allowed. The current
regulations must be complied with and, at all times, the designer's criteria must be
followed.
·
Before connecting the cables, check that the electrical installation is disconnected
and that there is no voltage between the cables.
·
Once installed, the device must comply with the following directives:
- Low Voltage Directive 2006/95/CE
- Machinery Directive 2006/42/CE
- Electromagnetic Compatibility Directive 2004/108/CE
·
Once these operations have been carried out, it is necessary to verify the tightening
of all the electrical connections (a badly tightened cable can cause irreparable
damage).
·
Check that the earthing has been carried out and that the thermal and over-current
protections have been regulated according to the values established on the rating
plate.
·
As a safety measure, if the fan runs out of voltage, it must be made so that all
other electrical elements are without voltage.
5.4.1. CONNECTING WITH ZONAIR3D CONTROLLER
·
Strip the power cable and connect it to 230v (50 / 60Hz)
general. It is
recommended electrical protection type and connected to the control panel fire
alarm.
·
Make sure that the probe connection cables are correctly switched (5 and 6) and
(17 and 18) in their respective strips that come from.
·
Pressure switch connection:
·
Open the transparent cover of the differential pressure switch (2 star screws)
·
Set the pressure switch according to the indications p. 12.
·
Remove the connecting strip from the pressure switch cable terminals; and connect
passing the cables to terminals 1 and 2 through the M16 gland of the pressure switch
inside the pressure switch, taking care that they do not touch and that replace the
transparent lid well.
·
Screw the transparent cover back on.
·
Fix the pressure switch in the position indicated by means of the self-tapping
screws provided, on the side of the machine are the fixing holes.
·
Cut to size and connect the transparent tube (from the + socket to the
pressure ; and from the socket - to the pressure switch input -), firmly (in
the pressure switch must reach the second thickness).
