Compliance with the following instructions is mandatory to ensure the functionality and
safety of the product. If the following instructions given are not observed, the product may not
operate safely and may cause a hazard.
Deviations from the following requirements may therefore lead to both to the loss of the
statutory material defect liability rights and to the liability of the buyer for the product that
has become unsafe due to the deviation from the specications.

1. OPERATIONAL AREA
Woods Plate fans (type designation see rating plate) with integrated external rotor asynchronous motor are ready
to use products, designed as components for air-conditioning, air supply and air extraction. A special motor design
makes speed control by voltage reduction possible.
The fans may not be operated until they are installed in line with their intended use. The supplied and certied
guard grille of Woods Plate fans is designed in accordance with DIN EN ISO 13857 Table4 (from the age of 14 up).
In the event of deviations, further structural protective measures must be taken for safe operation.

2. SAFETY INSTRUCTIONS
• The fans are intended for the transportation of air of mixtures that are like air. Usage in potentially explosive
areas for the transportation of gas, mist, vapors or their mixtures is not permissible. The transportation of solid
materials or similar materials in a transport media is also not permissible.
• Mounting, electrical connection and commissioning must be carried out by trained personnel (denition in
DIN EN 50 110 or IEC 364).
• Electrical hazard! The rotor is not protected against indirect contact neither by supplementary or reinforced
insulation nor by connection to safety-earth in accordance with IEC 60204-1, therefore the system constructor
must provide protection by enclosure in accordance with IEC 61140 before the motor is connected to a power
source. This protection can be achieved for example by a guard grille.
• The fan is only to be operated within the ranges specied on the type plate! Use the fan only in authorized
fashion and only for the tasks and ow media specied in the order!
• Fans are not designed for walking on even with an additive diusor attachment (retrot kit)! Do not climb
onto fans without suitable aids.
• The temperature monitors (TB) or PTC built into the winding serve as the motor protection and must be
connected.
• In models using PTC’s, comply with the permissible test voltage max 2.5V!
• For motors without temperature monitors a motor protection switch obligatory must be used!
• The EMC guideline is to be observed in connection with our control units. If the fans are completed with
components of other manufacturers, the manufacturer or operator of the entire plant is responsible for
keeping to the EMC guideline 2014/30/EU.
• Pay attention to the notes which concerning maintenance and service.
• These assembly instructions are part of the product and are always to be kept accessible.

3. TRANSPORT AND STORAGES
• Wear safety shoes and gloves for handling!
• Observe the weight data on the type code.
• Do not transport the fan by the connecting cables!
• Avoid impacts and collisions, especially on fans set-up on devices.
• Watch out for possible damage to the packaging or fan.
• Store the fan in the original packaging in a dry area protected from the weather or protect it from dirt and
weather until nal installation.
• Avoid exposure to extreme heat and cold.
• Avoid excessive storage periods and inspect the motor bearings for proper operation prior to installation.
4. MOUNTING
• Do not loosen the impeller, fan or balancing weight. Installation and electrical connection should only be
carried out by trained and qualied personnel. Wear safety shoes and gloves for handling!.
• The installation and security information are harmonized with the valid standard and guidelines
(DIN EN ISO 12100 / 13857).
• Avoid structural damage or stress with installation. Make sure the surface is at and even.
• Ensure the clearance gap between the impeller and the casing is maintained. Distortion due to uneven
surface may lead to fan failure due to bushing against the fan wheel. A minimum head gap “A” of 2.5mm
in all installation positions is necessary.
• Protective measures must be taken against falling parts when mounting with a hanging rotor.
• In the case of a vertical motor axis the respective lower condensation drain hole must be open (does not apply
to protection class IP55 fans).
• Make sure condensation drain-holes of the motors are not blocked.
• Connect fan only to electrical circuits that can be disconnected with an all-pole isolating switch.
Electrical connection corresponding to connection diagram a) in terminal box and b) by cable design connection
diagram on cable or on wall ring.

‘• Do not use metal compression-gland ttings with plastic terminal boxes.
• Use a dummy plug seal for the compression-gland tting.
• When opening cable glands on the fan/motor, check the condition of the threaded connections and seals.
• Only use lines which can guarantee a permanent seal around the cable glands.
• Depending on the type pf cable gland, attach a water drain sleeve or use a sealing compound.
• Screw on plastic terminal box covers should be sealed with sealant.
• Starting torque for screw on covers, plastic version 1.3 Nm, metal version 2.6 Nm.
• Secure fan connection cable with cable fasteners or cable clips.
• Depending on the model the motors
- Can be equipped with PTC’s, internally connected thermal contacts, lead-out thermal contacts or without
thermal protection.
• Connect them as below:
- PTC on PTC triggering device
- Internally connected thermo-contact: no external connection feasible or necessary.
- Lead-out temperature monitors must be integrated in the control circuit in such a way that, if a fault occurs,
the motor cannot switch on again automatically after it has cooled down. The protection of several motors
using one protection device is possible by connecting the temperature monitors of the individual motors
in series. It must be remembered that if a temperature fault occurs at one motor, all motors will then be
switched o. In practice, motors are therefore assembled in groups so that emergency operation with
reduced performance is still possible if a motor fails.
- Without thermal protection: use a motor protection switch!
• When in fan motors for 1~230V +/-10% the mains voltage is permanently over 240V, in extreme cases the
temperature monitor can trigger. In such cases a capacitor-type with the next smaller capacity should be used
instead of the stated capacity.

5. OPERATING CONDITIONS
• Do not operate fans in an explosive atmosphere.
• Duty type of fan
- Continuous operation with occasional starts (S1) according to DIN EN 60034-1:2011-02.
- Occasional starting between -40°C and -25°C is permissible.
- Continuous operation below -25°C only with special bearings (on request).
- Any use below -10°C is dependent on not being subjected to unusual, sudden or mechanical loads or
stresses on the material
• Woods Plate Fans are suitable for operation with frequency inverters when the following points are compiled:
- Between the inverter and the motor, sinusoidal lters should be incorporated which are eective for all
phases (sinusoidal output voltage, phase against phase, phase against protective conductor) as oered by
manufacturers.
- du/dt lters (also called motor or suppression lters) cannot be used in place of sinusoidal lters.
- When using sinusoidal lters, screened motor leads, metal terminal boxes, and a second earth connection to
the motor, if necessary, can be omitted. Check back by the manufacturer of sinusoidal lter.
• If the operational leakage current exceeds 3.5mA, earthing in compliance with DIN EN 50 178, art. 5.2.11.1
must be provided. For this purpose, there is a connection for a second protective earth on the stator ange.
Tightening torque 2.7 Nm.
• When speed controlling through electronic voltage reduction (phase control), depending on the installation
situation, increased noise formation caused by resonances can occur. In such cases we recommend the use of
a frequency changer with integrated sine lter.
• Woods EC fans are with EC motors with maximum eciency. Highly ecient, electronically commutated motors
with permanent magnets are used, the speed of which is controlled by the integrated controller.
• The devices of the EC fans are constructed in accordance with the general requirement in EN61800-2 for
adjustable speed electrical power systems and is intended for one-quadrant drives.
• We cannot guarantee that competitive makers of voltage control devices and frequency converters will function
properly and not damage the motor when used for a rotational-speed control of our fans.
• IP55 fans with a seal which is rubbing may cause additional noise.

6. START-UP
• Before rst-time start-up check the following:
- Installation and electrical connection have been properly completed?
- Electrical connection carried out in accordance with wiring diagram
- Turning diagram corresponds to turning direction arrow on fan housing. The airow direction or turning
direction determines the functionality of the fan, not the motor rotation eld.
- Is the protective earth connected?
- Connection data complies with the specications on the type plate.
- Motor operating capacitor data complies with the specication of the type plate (1 ph).
- Safety equipment is in place.
- Temperature monitor/motor protection switch are professionally connected and operating properly.
- All leftover installation materials and other foreign materials have been removed from the fan cavity.
- Cable gland is sealed.
- Do the installation position and the arrangement of the condensation drain holes in the motor corresponds
to each other (does not apply to protection class IP55 fans).
• The designated use of Woods Plate fans with VDE certication assumes connection in a device or via a control
unit.
• Start-up may only begin when all safety instructions have been veried and any hazards have been ruled out.
• Check for low vibration operation, strong vibration due to erratic operation (unbalanced), e.g. caused by
transportation damage or improper use, can lead to failure.
7. COMMUNICATIONS OPTIONS FOR EC FAN PROGRAMMING
Depending on the connection version and the auxiliary modules installed, there are dierent options for
communicating with the EC fan motor.
• With the ECBlue Basic connection version, the “AM-MODBUS-WB” auxiliary module provides an additional
option for programming using a mobile app.
• The MODBUS interface in the ECBlue BASIC-MODBUS connection version and the ECBlue Basic with AM-
MODBUS auxiliary module enables programming using the A-G-24NW hand-held terminal or a PC software.
For detailed information on installation and operation, please contact Woods Air Movement.

8. MAINTENANCE, REPAIR, CLEANING
• During all work on fan in the hazardous area:
- Maintenance work to be only performed by trained service personnel.
- Observe the safety and labour regulations (DIN EN 50 110, IEC 364).
- The rotor must be stand still!
- Open the electrical circuit and secure against being switched back on.
- Verify the absence of voltage.
- No maintenance work on running fan.
• Wear safety shoes and gloves for handling.
• Keep the airways of the fan free – danger because of objects dropping out!
• Wet cleaning under voltage may lead to an electrical shock – danger to life!
• Regular inspection, if necessary, with cleaning, is required to prevent imbalance due to ingress of dirt.
• Do not use any aggressive, paint solvent cleaning agents when cleaning.
• Never use a high-pressure cleaner or spray jet to clean.
• Avoid letting water permeate into the motor and the electrical installation.
• After cleaning the motor must be operated for 30 mins at 80-100% of the max. speed to let it dry out.
This will allow any inside water to dry out.
• Ball bearing service life
- According to standard calculation methods, bearing service life expectation of the motor integrated ball
bearings is mainly determined by the grease service life F10 and amounts for standard application to
approx. 30,000 to 40,000 operating hours. The fan or motor is maintenance-free due to the use of ball
bearings lifetime lubrication. Once the grease operating life F10h has been reached, it may be necessary
to replace the bearing. The bearing service life expectation may change compared to the specied value,
if operating conditions such as increased vibration or shocks, increased or too low temperatures, humidity,
dirt in the ball bearing or unfavourable control modes are present. A service life calculation for special
applications can be provided on request.
• The service life of EC fans with power electronics is decisively dependent on the ambient temperatures.
The longer electronic components are exposed to high ambient temperatures, the faster the deterioration
and the more probable the failures. The power electronics protects itself against excessive temperatures by
active temperature management (power reduction).
• Take note of abnormal operating noise.
• Watch-out for vibration free motion.
• Please consult our service department with regards to changing the bearing as for all other damage
(e.g. to the coil).
• On 1 phase motors, condenser rating can decrease with time, life expectancy approx. 30,000 hours, as per
DIN EN 60252.
• Outdoor fans – if a fan is stationary for long periods in a moist atmosphere, it should be switched ON for
minimum of 2 hours every month to remove any moisture that may have condensed within the motor.
• Fan with IP55 degree of protection or higher: open the existing sealed condensation bores at-least every
6 months.
