IN INTERMEDIATE CONNECTIONS, BOXES THAT COMPLY WITH THE F400 DEMANDS MUST BE USED (CAREFULLY
READ THE F400 MOTOR MANUAL INSTRUCTIONS). CABLES CATALOGUED AS "FLAME RESISTANT" WHICH DON'T
GUARANTEE A F400 SERVICE ARE NOT SUITABLE FOR THIS FUNCTION. WOODS AIR MOVEMENT RECOMMENDS
VS OMERIN BRAND CABLES WHICH HAVE BEEN PROPERLY TESTED WITH OUR FANS.
EVERY FAN WIRING ELEMENT AND COMPONENT SHOULD BE CORRECTLY SELECTED AND INSTALLED TO COMPLY
WITH THE F400 STANDARDS. SPECIAL ATTENTION MUST BE PAID TO ALL METAL STRUCTURAL PARTS, WHICH MUST
REMAIN CORRECTLY CONNECTED TO THE GROUND TO PREVENT ANY ELEMENT FROM GETTING ELECTRICALLY
LOADED AND TO AVOID ELECTROSTATIC DISCHARGES.
In the models shown, connection should always be done by using the thermal protection incorporated in the motor
(SEE FAN MAINTENANCE SECTION).
9.3 VOLTAGE AND FREQUENCY
Carefully read the F400 motor manual instructions. The motor power supply should be made in accordance with
the voltage and frequency shown on the fan plate. Variations of 5% in the electrical network for the nominal
voltage indicated are permitted. If the connection used cannot support this level, there may be a danger of the
motor burning out. Therefore, ensure the selected Y-? disposition in the motor corresponds to the network voltage
and frequency by using a tester.
9.4 CONSUMPTION:
Once the fan has been installed, and the load does not exceed that shown on the plate, you can control the
consumption. The fan's capacity and the installation load should be correctly adjusted (SEE THE OPERATING
SECTION). In case of non-compliance, consult the manufacturer.
9.5 GROUNDING
If the fan is a Class I machine that complies with the current standard, it is vital to correctly carry out connection
of the grounding through the socket, which can be found inside the motor or the fan's terminal casing. Once this
connection has been carried out, it is recommended that the resistance between the exterior conductor and the
fan casing should not be greater than 0,l?

However, there may be exceptions. In the EXTERNAL models (during normal service of DUAL application), but
independently of the motor's thermal class, it is recommended that the air temperature does not exceed 40°C, and
to keep the humidity below 60% in the cooling surroundings of the motor. This will ensure the motor is kept cool
and, at the same time, prolong its duration. The maximum air temperature in a continuous service should range
from 40
C to 55
C.

In each case it is recommended that users consult the information in the technical catalogue to establish the
particular detailed characteristics of each fan range and model. For other more severe applications, some special
characteristics may be applied. Always consult the technical sheet for each particular fan, and for more information
contact the manufacturer.
9.7 ROTATION DIRECTION
This is shown by the arrow on the fan's casing. To invert the three-phase rotation of a one or two velocity motor,
interchange the two phases. In single phase motors, this can only be changed in some models. Consult the
diagrams in each case.
