Usage Features

Installation:

• The device must be transported, unpacked, installed, operated, maintained, and otherwise used by suitably qualified, trained, and authorized technical staff.
• Only authorized specialists are permitted to install the device, carry out a test run, and perform work on the electrical installation.
• Secure the device against unintentional loosening, e.g., using self-locking screws.
• Ensure the device is securely positioned until all fastening screws are tightened to prevent damage from slipping.
• The device has external leads. The "PE" (protective earth) must be connected first.
• Cables should be connected according to the application, observing the connection diagram.
• Ensure isolation from the supply (all phases) before checking connections.
• The device may only be switched on if it has been installed properly and in accordance with its intended use, including required safety mechanisms and professional electrical hookup.
• Before switching on, check for visible external damage and ensure protective devices are functional.
• Check the fan's airflow paths for foreign matter and remove any found.
• Apply the nominal supply voltage.
• To switch off, disconnect the device from the power supply at the supply line's main switch, disconnecting the ground connection last.

Electrical Connection:

• Always connect a protective earth first and check its integrity.
• Use only cables that meet specified installation regulations for voltage, current, insulation material, and capacity.
• Route cables to prevent contact with any rotating parts.
• Prevent water ingress into wires or cables at the customer end to avoid device damage.
• Connect the device only to circuits that can be switched off with an all-pole disconnection switch.
• Verify nameplate data matches connection data and operating capacitor data.
• Ensure power supply matches device voltage.
• Use cables designed for the current level indicated on the nameplate, with cross-section determined according to EN 61800-5-1. The protective earth must have a cross-section equal to or greater than the phase conductor.
• Recommended use of 105 °C cables, with a minimum cross-section of AWG 26 / 0.13 mm².
• Ground conductor contact resistance according to EN 60335 must be verified in the end application. An additional protective earth conductor may be necessary depending on installation circumstances.

Voltage Control:

• With speed control using transformers or electronic voltage regulators (e.g., phase control), excessive current may occur. Noises may also occur with phase control depending on installation.
• For operation with variable frequency drives, install sinusoidal filters on all poles (phase-phase and phase-ground) between the drive and the motor. This protects against high-voltage transients and harmful bearing currents.
• Heating of the motor due to variable frequency drive use must be checked by the customer in the application.

Safety Warnings:

• DANGER (Electrically charged device): Risk of electric shock. Stand on a rubber mat when working on an electrically charged device.
• WARNING (Live terminals): Risk of electric shock even when switched off. Wait five minutes after disconnecting voltage before opening.
• CAUTION (Rotor and impeller energized): In case of a fault, do not touch the rotor and impeller once installed.
• CAUTION (Automatic restart): The motor restarts automatically when operating voltage is applied. Keep out of the danger zone. Switch off line voltage and ensure it cannot be switched back on. Wait for the motor to stop.
• WARNING (Rotating device): Long hair, loose clothing, and jewelry can become entangled. Wear a cap and avoid loose items.
• WARNING (Ejected parts): Missing protective devices can allow balancing weights or broken fan blades to be ejected. Install guard grilles and keep out of the exhaust zone.
• CAUTION (Hot surface): High temperature on motor housing. Ensure sufficient protection against accidental contact.
• CAUTION (Transport): Crushing hazard. Wear safety shoes and cut-resistant gloves. Transport in original packaging only. Secure the device to prevent slipping.
• WARNING (Hot motor housing): Risk of fire. Ensure no combustible or flammable materials are near the motor.
• CAUTION (Cutting and crushing hazard): Carefully remove from packaging, avoid shocks. Wear safety shoes and cut-resistant gloves.
• CAUTION (Possible damage): If the device slips during installation, serious damage can result. Secure the device until all fastening screws are tightened.
