  • Fasten the fan to the substructure without distorting it.
• Check the device for transport damage. Damaged devices must no longer be installed.
• Install the undamaged device according to your application.
• CAUTION
  • Possibility of damage to the device
  • Serious damage may result if the device slips during assembly.
• Keep the device fixed in position at the installation location until all attachment screws have been tightened.
• The fan must not be strained on fastening.

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 that the data on the type plate match the connection data.
• 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 cross-section. We recommend the use of 105°C cables. Ensure that the minimum cable cross-section is at least AWG26/0.13 mm².

• Protective earth contact resistance as per EN 60335
  Compliance with the resistance specifications as per EN 60335 for the protective earth connection circuit must be verified in the application. Depending on the installation situation, it may be necessary to connect an additional protective earth conductor by way of the extra protective earth terminal provided on the device.

Voltage control

NOTE
Excessive current may occur with speed control using transformers or electronic voltage regulators (e.g. phase angle control). In addition, depending on how the unit is installed, noise and vibration can occur with phase angle control. Vibrations can lead to bearing damage, which can lead to premature failure.

• Heating-up of the motor when using voltage control must be checked by the customer following installation in the end device.

Frequency inverter

• For operation with frequency converters, fit sinusoidal filters that work on all poles (phase-phase and phase-earth) between the frequency converter and the motor.
• During operation with frequency converters, an all-pole sine filter protects the motor against high-voltage transients that can destroy the winding insulation system, and against harmful bearing currents.
• Please use a frequency converter only after consultation with ebmpapst.
• Heating-up of the motor when using a frequency converter must be checked by the customer following installation in the end device.

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.\

Cable routing

• No water may penetrate along the cable in the direction of the cable exit.

• NOTE
  Damage caused by moisture penetration. Moisture can penetrate into the terminal box if water is constantly present at the cable glands.

  • To prevent the constant accumulation of water at the cable glands, the cable should be routed in a U-shaped loop (siphon) wherever possible.
  • If this is not possible, a drip edge can be produced by fitting a cable tie directly in front of the cable gland for example.
