Checklist components

General recommendations
Before start assembly fan: read instruction manual and understood it completely.
Handling: Fan is heavy,so before moving must be checked to have all right equipment in order to avoid accident to
people or environment,person working with fan must be informed and formed in order to be able to use right
equipment according to local law .
Machine features:
I.IP 65 motor protection grade
II.Inverter following EMC norms.
III.Electrical connection done using fast connecting solution,in order to accelerate installation and substitution
Identification data: For any communication with the manufacturer or service centres alway quote these
references..

During installation:
1. Pull always the yellow wire ( Modbus A) and the Green wire (Modbus B) down to the switchboard (to connect
with the fan).
2. Write down the serial number and Modbus address of each motor in a diagram, as well as their location (so
that each machine can be uniquely identified) in the event of maintenance..
3. Check that no two motors with identical Modbus addresses are located on the same line.
These three points are essential as maintenance and diagnostic work on the fan can be carried out remotely, but to
do so it is necessary to identify the fan exactly in order to connect to it.
Please note, even if the WA1400 Standard is not running, there is power on the fan at all times.
During maintenance or repair, the power cable should be de-energised at all times.
This can be done by means of the installed work switch and place it in a locked position.

Cable connection

First start
After having assemble complete fan ,connected power and controler lines,give power to machine and wait about 30
seconds until it start to run,because machine need 30 seconds to autoset all parameters.
ATTENTION : All blades must be fitted to enable the motor to start.
After that check following:
I. No rotation unbalancing due to wrong components assembly.
II. No noise coming out from machine.
III. Motor led light every 2 seconds to test everything is fine.
IV. Rotation of the fan must be anticlockwise when viwed from the front.

Electrical connections
POWER SUPPLY :
The power supply line is composed as follows:
I. A power supply panel supplied via a dedicated 3F+N+E 200-480V 50/60 Hz line provided upstream of
a suitable MT (magnetotermic protection) and a class A differential protection with a sensitivity of at
least 300mA, the line must be constructed with a cable according to the load present.
II. The distributed electrical power cable (PE) must be connected to an earthing system with an
impedance and characteristics that guarantee the correct operation of the installed earth leakage
protection in accordance with the regulations in force concerning indirect contacts and the non-
propagation of stray currents. The shielding of the cable to the PE earth terminal must only be
provided on the side of the switchboard and not in the fan.
ATTENTION ! The line with MT+D must be dedicated and must not therefore supply other loads, nor must it
be derived from other differential types other than A.
SIGNAL:
The fan must be connected by means of the specific connector to a 4x2x0.5 mmq LIYCY signal cable prepared
for its management, capable of transmitting both an analogue signal (0-10V voltage for speed control and
management) and a Modbus signal able to allow control and the possibility of modifying the parameters via a
remote PC.
If the signal line includes junction boxes in which the signal cables of the individual fan are connected, the
same 4x2x0.5 mmq LIYCY cable used for the signal line must be used between the junction box and the
inverter signal connector.

T-piece not included, installer can loop through via a junction box.
Number of fans to loop through
The installer knows this and it depends on the electricity group. Power is not supplied via the fan controller. 400V is
applied via the isolating switch. Only the 0-10V signal comes from the fan controller.
