For cyclic speed loads, note that the rotating parts of the device are designed for maximum one million load cycles. If you have specific questions, contact ebm-papst for support. 

## **Cutting and crushing hazard when removing blower from packaging** 

   - →Carefully remove the blower from its packaging by grasping hold of the housing. Never subject to impact.# 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. 

## **CAUTION**

**G2E120-AR38-01** 

## Operating instructions 

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

- →When working on the device, you must switch off the system/machine in which the device is installed and secure it from being switched on again. 

## **NOTE** 

## **4.3 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. 

## **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. 

## **4.2.1 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. 

## **4.2.2 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. 

## **4.2.3 Frequency inverter** 

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

- 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. 

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

- →Wait five minutes after disconnecting the voltage at all poles before opening the device. 

## **CAUTION** 

**Electrical load on the capacitor after device is switched off** Electric shock, risk of injury 

- →Discharge the capacitors before working on the device. 

## **CAUTION** 

**The motor restarts automatically when operating voltage is applied, e.g. after a power failure.** 

Danger of injury 

- →Keep out of the danger zone of the device. 

- →When working on the device, switch off the mains supply voltage and secure the latter from being switched on again. 

- →Wait until the device stops. 

- If the device remains out of use for some time, e.g. when in storage, we recommend switching the device on for at least two hours to allow any condensate to evaporate and to move the bearings.
