Function Description

The VBH0450CTTPS is an EC (electronically commutated) fan, primarily designed as a built-in device for air conveyance according to its technical data. It operates in power systems with grounded neutral (TN/TT), phase conductor grounding, or IT power systems, adhering to EN 50160 network quality characteristics. The device is intended for stationary systems and performs all necessary maintenance work. It conveys air at ambient air pressures between 800 mbar and 1050 mbar and within its permitted ambient temperature range. The fan is equipped with all protective devices and must be operated following these instructions.

The fan features electronic motor protection, including rotor position detection error, blocked rotor detection, line undervoltage/phase failure detection, and thermal overload protection for electronics/motor. It also includes a vibration sensor. The device has an integrated PI controller and configurable inputs/outputs (I/O). It supports MODBUS V6.3 for communication and offers soft start functionality. An external 15-50 VDC input is available for parameterization, and a voltage output of 3.3-24 VDC (Pmax = 800 mW) is provided for external devices.

Usage Features

Safety:

• Staff Qualifications: Only suitably qualified, trained, and authorized technical staff may transport, unpack, install, operate, maintain, and use the device. Authorized specialists are required for installation, test runs, and electrical work.
• Basic Safety Rules: Local industrial safety regulations must be observed. No modifications or additions without ebm-papst approval. Use only approved replacement parts.
• Electrical Safety: Always connect protective earth first. Live terminals and connections even when switched off. Wait five minutes after disconnecting voltage before opening. In case of fault, rotor and impeller may be energized. Control voltage or stored speed set value can cause automatic restart.
• Mechanical Safety: Rotating device poses risk of injury; secure against accidental contact. Wait until all parts stop before working. Missing protective devices can lead to ejected parts. Long hair and dangling items can become entangled.
• Hot Surface: Electronics housing can reach high temperatures; ensure protection against accidental contact.
• Transport: Transport with care in original packaging to prevent bearing damage or deformation. Secure fan(s) to prevent tipping.
• Storage: Store in a dry, clean environment, protected from weather and vibration, in original packaging. Recommended storage period is no longer than one year. Maintain storage temperature as per specifications.
• Mounting: Use appropriate hoisting equipment and lifting devices. Use four round slings passed around the struts of the support bracket. Ensure struts are vertical. Do not exceed 2g acceleration during transport.
• Electrical Connection: Check nameplate data against connection data. Use cables designed for indicated current level. Protective earth cross-section must be equal to or greater than phase conductor. Recommended 105 °C cables, min AWG 26/0.13 mm². Compliance with EN 61800-5-1 for protective earth contact resistance must be verified.
• Terminal Box: Strip cables only as far as necessary. Ensure cable gland is sealed and no strain on connections. Use seals in cable gland if necessary. Route supply and control cables separately. Connect protective earth first (tightening torque 3.5 ±0.4 Nm). Ensure wires do not splay out when connecting.
• Cable Routing: Prevent water ingress into cable gland by routing cable in U-shaped loop or using a drip edge.
• Switching On/Off: Only switch on if properly installed with all safety mechanisms and electrical hookup. Check for external damage and functional protective devices. Ensure no foreign matter in air flow paths. Apply nominal supply voltage and start by changing input signal. Switch off via control input; do not cycle power supply. Disconnect from power supply for maintenance.
• Speed Range Suppression: The integrated sensor can measure vibration velocities. Speed ranges with excessive vibration can be blocked out using EC-Control software to prevent continuous operation in resonant ranges.

Improper Use (Prohibited and Hazardous):

• Operating in an unbalanced state (dirt, ice).
• Resonant operation or severe vibration.
• Operation in medical equipment with life-sustaining functions.
• Conveying solids or abrasive particles in the flow medium.
• Painting the device.
• Loose connections during operation.
• Opening terminal box during operation.
• Conveying highly corrosive air (unless specifically designed for it).
• Conveying air with high dust content.
• Operating near flammable materials or in explosive atmospheres.
• Using as a safety component or for safety-related functions.
• Operation with disassembled or manipulated protective devices.
