USER'S GUIDE R14 AXIAL FAN , Code: 0000, Iss: 9.07.2019

INSTALLATION AND CONNECTION

This unit should only be installed by a qualified technician. Inspect the motor bearings for proper operation prior to installation.

Do not install the fan on an unstable surface. First install the device on the application, than connect the protective earth!

The method of fixing stated is not to depend on the use of adhesives since they are not considered to be a reliable fixing means.

The fan is primarily constructed for installation with rotor on bottom or with shaft in horizontal. For other possibilities please contact for manufacturer's

support.

Ensure that the air-gap between the fan impeller and the stationary housing is constant. Distortion due to an uneven surface of basis may lead to a fan

failure. Air-gap between blade and cone-inlet (housing) should be of min. 3 mm.

Fan must be fixed to stationary housing 4x M8 at 90° on diameter 700mm as indicated on enclosed technical drawing. Use screws with property class

of 8.8. Secure all threaded joints with e.g. Loctite or by using self-locking screws.

The system manufacturer or the machine builder is responsible that the inherent installation and security information are harmonized with the valid

standards and guidelines (ex. EN 13857). To prevent dangerous situation and possible injuries the height and the diameter of inlet cone must be

appropriate dimensions.

Main electrical installation must be protected against short circuit with e.g. circuit breaker: max.16A, 400Vac, Type B and installation must be

constructed properly according to valid national directives.

Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.

The fan is intended only to be connected to the fixed wiring or application's circuit. An all-pole separating switch which must be incorporated to wiring

must disconnect also the fan.

This product can cause a d.c. current in the protective earthing conductor. Where a residual current-operated protective device (RCD) or monitoring

(RCM) device is used for protection in case of direct or indirect contact, only an RCD or RCM of Type B+ is allowed on the supply side of this product

and recommended sensitivity is 300mA with short time delayed intervention.

The electrical connection must correspond to the enclosed connection diagram.

Recommended cable for power supply and alarm-relay contact is an ordinary PVC cable acc. to IEC 60227-5 (eg. H05V2V2-F, 4G 1 mm²), no longer

than 2m, outer diameter 4.5 - 9.5mm. Power supply cable could include also additional leads for alarm circuit. Recommended cable for control circuit is

an ordinary PVC cable (eg. H05VV-F, 5X 0,5 mm²) , no longer than 2m, outer diameter 4.5 - 9.5mm and must be sufficient separated from the supply

circuit.

Ends of stranded wires needs to be provided with insulated ferrule (pin). Easier way to connect wires to the terminals if you use a screwdriver of

2.5x0.4mm dimensions to press the spring of terminal first and then insert the wire into the WAGO PUSH-WIRE® terminal. A screwdriver of 2.5x0.4mm

is necessary tool to remove conductor from the terminal.

Fan performed with terminal box is as supplied fitted with a sealing plug in the cable glands as a preventive against ingress of water or moisture inside

the terminal box. If the cable is not installed through the cable gland, sealing plug must remain in the gland!

Secure connection cable to the fan guard grill or to the motor holder with cable fasteners so that the water flows away from the cable and cable gland.

Try to maintain as much distance between supply and control cable as possible (recommended distance > 5cm).

Cable-end of the fan must be connected in a dry environment to prevent that water penetrate through cable into motor housing.

Where the fan is installed in shaft-horizontal position, the cable exit on the motor must be in down position.

Before putting into operation, check the resistance of protective-earth circuit of the entire application. Cross-sectional area and material of PE conductor

may be the same as cross-sectional of phase conductor or see guide regarding PE conductor : standard EN 61800-5-1.

A second protective earthing conductor must be installed to ensure requirements of standard "EN 61800-5-1 , 4.3.5.5.2 Touch current in case of failure

of protective earthing conductor ". For that purpose an additional M4 of 12mm depth hole or additional PE terminal is provided on motor housing and

marked with PE symbol. More information about dimensions of second PE conductor please find in guidelines of mentioned EN or equivalent standard

(a cross-section of second Cu conductor should never be less than 2.5mm
