Improper use
Using the device in the following ways is particularly prohibited and may cause hazards:

• Operating the device with an imbalance, e.g. caused by dirt deposits or icing.
• Moving air that contains abrasive particles.
• Moving highly corrosive air, e.g. salt spray mist. Exceptions are devices that are intended for salt spray mist and protected accordingly.
• Moving air that contains dust pollution, e.g. suctioning off saw dust.
• Operating the device close to flammable materials or components.
• Operating the device in an explosive atmosphere.
• Using the device as a safety component or for taking on safety related functions.

CONNECTION AND START-UP

Connecting the mechanical system

CAUTION
Cutting and crushing hazard when removing the fan from the packaging

• Carefully hold the impeller to remove the device from its packaging. Make sure to avoid any shock.
• Wear safety shoes and cut-resistant safety gloves.
• Check the device for transport damage. Damaged devices must no longer be installed.
• Install the undamaged device according to your application.

Connecting the electrical system

DANGER
Electric voltage on the device
Electric shock

• Always install a protective earth first.
• Check the protective earth

DANGER
Incorrect insulation
Risk of fatal injury from electric shock

• Use only cables that meet the specified installation requirements for voltage, current, insulation material, load etc.
• Route cables such that they cannot be touched by any rotating parts.

CAUTION
Electrical voltage
The fan is a built-in component and features no electrically isolating switch.

• Only connect the fan to circuits that can be switched off with an all-pole separating switch.
• When working on the fan, you must switch off the installation/machine in which the fan is installed and secure it from being switched on again.

NOTE
Water penetration into leads or wires
Water enters at the cable end on the customers side and can damage the device.

→ Make sure that the cable end is connected in a dry environment.

Connect the device only to circuits that can be switched off using an all-pole disconnecting switch.

Prerequisites

• Check whether the data on the type plate agree with the connection data and the data of the operating capacitor.
• Before connecting the device, ensure that the supply voltage matches the operating voltage of the device.
• Only use cables designed for current according to the type plate.
  For determining the cross-section, follow the basic principles in accordance with EN 61800-5-1. The protective earth must have a cross-section equal to or greater than the outer conductor crosssection.
  We recommend the use of 105°C cables. Ensure that the minimum cable cross- section is at least AWG26/0.13 mm².

Earth wire contact resistance in accordance with EN 60335
Compliance with the impedance specifications in accordance with EN 60335 for the protective earth circuit must be verified in the end application.
Depending on the installation situation, it may be necessary to install an additional protective earthing conductor via the additional protective earth connection point available on the device.

Voltage control
With open loop speed control using transformers or electronic voltage regulators (e.g. phase angle control), excessive current may occur.
In addition, noises can occur with phase angle control depending on the mounting situation.

Frequency inverter
Please use a frequency converter only after consultation with ebm-papst.

Fit sinusoidal filters that work on all poles (live-live and liveearth) between the frequency inverter and the motor for operation with frequency inverters.
Depending on how the device is installed, noises may occur.

Heating of the motor due to use of a frequency converter must be checked in the application by the customer.

Connection of the cables
External leads are brought out of device

• First connect the “PE” (protective earth) connection.
• Connect the lines according to your application. When doing so, observe chapter 4.4 Connection screen.

**Connection screen

**

Checking the connections

• Make sure that the power is off (all phases).
• Secure it from being switched on again.
• Check the correct fit of the connection lines.

Switch on device
The device may only be switched on if it has been installed properly and in accordance with its intended use, including the required safety mechanisms and professional electrical connection. This also applies for devices which have already been equipped with plugs and terminals or similar connectors by the customer.

WARNING
Hot motor housing
Fire hazard

• Ensure that no combustible or flammable materials are located close to the fan.
• Inspect the device for visible external damage and the proper function of the protective features before switching it on.
• Check the air flow paths of the fan for foreign objects and remove any that are found.
• Apply the nominal voltage to the voltage supply.

Switching off the device

• Disconnect the device from the supply voltage at the main switch for the supply line.
• When disconnecting, be sure to disconnect the earth wire connection last.
