Control that the fan is installed and connected elec- trically in the right way, grounded and with motor protection. • For single phase fans a residual current device i used(type A).AC-MOTOR • For speed regulation of AC motor a transformer orthyristor can be connected.The AC motor has a built-in thermal contact. • The capacitor (only for AC motor) has finite life- time and should be exchanged after 45.000 opera- tion hours (about 5 years of operation) to secure maximum function. Defective capacitor can cause damage.1270384_utg4_CK_ACEC_SV_EN_DE.pdf 9 1270384_utg4_CK_ACEC_SV_EN_DE.pdf 9 1270384_utg4_CK_ACEC_SV_EN_DE.indd 99EC-MOTOR • Speed regulating of EC motor can be done with the built-in potentio-meter, 0-10 V. An external potentio- meter can be connected to the terminal if neces- sary. The internal poten- tiometer should then be disconnected.
