1. Installation and Connection

USER'S GUIDE R14 AXIAL FAN , Code: 0000, Iss: 21.09.2021

Electrical installation:

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.

First install the device on the application, than connect the protective earth!

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 or 6G 1 mm²

), no longer than 2m, outer diameter 4.5 - 9.5mm.

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

CONNECTING DIAGRAM : See appended technical drawing - CONNECTING DIAGRAM 0302-0-1008
