    (EN 60204-1). Only spare parts delivered by Honeywell can be used. At power-up, power brake or fault reset the motor will start immediately if the start signal is active, unless the pulse control for Start/Stop logic has been selected.
  • Page 6: Emc Levels

    EMC levels SmartDrive HVAC inverters are divided into three classes according to the level of electromag- netic disturbances emitted, the requirements of a power system network and the installation environment (see below). The EMC class of each product is defined in the type designation code.
  • Page 7: Total Harmonic Distortion (Thd)

    T-class. This class is very typical requirement also in installations in ships. Also the 230V SmartDrive HVAC products can be ordered as ready configured to this class by adding a T to the end of standard product code (HVAC230-xxx-xxT).
