Page 8: Description
| Description Description MUB equipped with an EC motor The fans are driven by EC motors. These motors are delivered with a pre-wired potentiometer (0–10 V) that allows you to easily find the required working point of the fan. All motors are suitable for 50/60 Hz. The input voltage for single- phase units can vary between 200 and 277 V for three phase units between 380 and 480 V. -

| Description 5.5.1 Sensor control module for differential pressure and volume PCA1000/6000D2 The factory setting of the controller is CAV (constant air volume). The measured value is compared with the setpoint value. The controller adjusts the 0-10 V controlled output for the EC motor to keep the air volume constant. The specific characteristics of the inlet cone size are considered in the k-factor. -

The ball bearing of the motor and the balanced impeller may be damaged by forceful impacts. ♦ Attach the impeller and/or the shaft extension to the shaft or the rotor without forceful impacts. ♦ Do not separate the impeller and the hub. They were balanced as one unit by Systemair. Note: The hub can be heated for easier assembly and disassembly, for example with a hot-air blower. - Page 20 | Installation The hub is shown without impeller due to better lucidity. Disassembly 1.
