CONNECTION AND START-UP Connect the device only to circuits that can be switched off using an all-pole disconnecting switch. 4.1 Connecting the mechanical system CAUTION Cutting and crushing hazard when removing the device from the packaging Blades can be bent → Carefully remove the device from its packaging, only touching the wall ring. 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. 4.2 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. DANGER Electrical load (>50 µC) between mains wire and protective earth connection after switching of the supply when switching multiple devices in parallel. Electric shock, risk of injury Translation of the original operating instructions → Make sure that sufficient protection against accidental contact is provided. Before working on the electrical connection, the connections to the mains supply and PE must be shorted. 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. 4.2.1 Prerequisites ; Check whether the data on the type plate agree with 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 crosssection. We recommend the use of 105°C cables. Ensure that the minimum cable cross-section is at least AWG26/0.13 mm². 4.2.2 Residual current operated device Only pulse-current sensitive and/or universal RCD protective devices (Type A or B) are permitted. Like frequency inverters, RCD protective devices cannot provide personal safety while operating the device. 4.2.3 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. 4.2.4 Frequency inverter Please use a frequency converter only after consultation with ebm-papst. When a frequency converter is used for speed adjustment, the maximum safe operating speed (see 3.2 Nominal data) may not be exceeded. 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. → 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. 4.3 Connection in terminal box NOTE Water penetration into leads or wires Water enters at the cable end on the customers side and can damage the device. 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. 4.3.1 Preparing connection lines for the connection → Make sure that the cable end is connected in a dry environment.

CAUTION Voltage The device is a built-in component with no isolating switch. ; Seal the terminal box. → Connect the device to a suitable tripping device. 4.3.3 Cable routing → Only connect the device to circuits which can be deenergised with an all-pole disconnection switch. 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). → When working on the device, the system/machine in which the device is installed must be secured so as to prevent it from being switched back on. NOTE Lack of motor protection Without motor protection, the motor can overheat and suffer damage. → Connect up the thermal overload protector installed in the coil. Translation of the original operating instructions The motors are equipped with thermal overload protectors to protect the devices. Check to make sure that the thermal overload protector is correctly connected before each operation. Failure to connect up the thermal overload protector correctly will invalidate your warranty claim. 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.
