Safety and protective functions

DANGER
Missing safety device and non-functioning safety device If there is no safety device, you could be seriously injured, for example if you reach into the running device or your hands are sucked into it.
→ Operate the device only with a fixed and isolating safety protection and a fixed guard grille. The guard must withstand the kinetic energy of a fan blade detaching at maximum speed.
→ The device is a built-in component. You, the owner/ operator, are responsible for providing adequate protection for the device.
→ Shut down the device immediately if you detect a missing or ineffective protective feature.

Mechanical movement

DANGER
Rotating device
Body parts that come into contact with the rotor and impeller can be injured.
→ Secure the device against accidental contact.
→ Before working on the system/machine, wait until all parts have come to a standstill.

WARNING

CONNECTION AND START-UP

Connecting the mechanical system

CAUTION
Cutting and crushing hazard when removing the fan from the packaging
→ Carefully remove the device from its packaging, only touching the guard grille. 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.

CAUTION
Electric shock
Electric voltage on the metal part
→ Use the device only with the cable guard and terminal box provided for this purpose.
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 cross-section.
  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 in terminal box

Preparing connection lines for the connection
Strip the cable just enough so that the screwed cable gland is tight and the terminals are relieved of strain. Tightening torque, see chapter 3.1 Product drawing.

Connecting cables with terminals

• Remove the cap from the screwed cable gland.
  Remove the cap only in those places where cables are inserted.

• Insert the line(s) (not included in the standard scope of delivery) into the terminal box.

• First connect the “PE” (protective earth) connection.

• Connect the lines to the corresponding terminals.
  Use a screwdriver to do so.
  During the connection work, ensure that no cables splice off.
  The terminal strip is equipped with a penetration prevention device.

• Insert the strands until they meet resistance.

• Seal the terminal box.

Cable routing
No water may penetrate along the cable in the direction of the cable gland.
Fans installed lying flat
Make sure that the cable is routed in the form of a loop (water trap).
Fig. 2: Fan installed lying flat, cable routed as a water trap.

Fans installed in upright position
When routing the cable, ensure that the screwed cable glands are arranged at the bottom. The cables must always be routed downwards.
Fig. 3: Cable routing for fans installed upright.

Connection screen

Open additional screwed cable glands

You have the ability to break a second cable gland opening through on the terminal box.

• WARNING
  In event of a fault, the screwed cable gland is under electrical voltage
  Electric shock
  → Do not use metal cable glands for plastic terminal boxes.

• Screw the cable gland into the pre-cut thread using a screwdriver.
  When doing so, note the tightening torques, see chapter 3.1 Product drawing.

• Remove the plastic tab that falls off when the wire is pressed through into the terminal box.
  Fig. 4: Screwed cable gland opening
  

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.
• Screw the terminal box cover closed again. Terminal box tightening torque, see chapter 3.1 Product drawing.
• Make sure that the terminal box is correctly closed and sealed and that all screws and screwed cable glands are properly tightened.

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.
