201.54 UltraComfortable indoor climate in high-end interiorsInstallation and operating instructionsThe fan runs when control voltage is applied or the stored fan speed startsup automatically when mains power fails.• Do not go near the hazard area of the unit.High temperatures are produced at the fan’s electronic housing.• Combustion hazard.The fan is protected from blockage. Protective functions are integrateddepending on the fan type, which cause the fan to switch off automaticallyin the event of diverse faults.• Please refer to the operating instructions for the respective fan for furtherinformation!Please read these instructions in full to ensure correct and proper installationand the correct operation of Ultra unit heaters.10.2 Motor protection10.2.1 AC fansThermal contacts (temperature monitors) are embedded in the motorwindings, which open when the maximum winding temperature of155 °C is exceeded. The motor is switched off whenever it impermissiblyheats up combined with an appropriate protective switch. The motor is thusprotected against overload operation, over- and undervoltage, unacceptablyhigh ambient temperature and the rotor jamming.Thermal contacts meet the conditions for protecting against overloadingof equipment with electric motor drive (VDE 0730). Commercial motorprotection switch or bi-metal trips are not suitable as motor protectionwith multi-stage operated motors. Only appropriately wired controllers ormodules or a similar type of switch may be used.Single-phase controllerThe thermal contacts lock the motor via the single-phase controller eachtime the motor heats up inadmissibly.Continuously variable power module type ... VThe thermal switch off the motor via the stage switch each time the motorheats up inadmissibly (without locking the motor!). A potential-free NCcontact offers the option to lock the 0-10 V control signal to “0 V” bymeans of an on-site controller.The unit is not short circuit-proof! The device will not work if the motorcable short circuits. Even when the motor is idle, the motor cables (U1 andU2) are still carrying mains potential!
