MOTOR WIRING
AND
START-UP
Note
:
It is strongly recommended to use a soft starter connected in series with the motor
power supply. Using a soft starter has the benefit of preventing drive belt damage
(destruction of belt teeth in shear) and of eliminating the electric load bursts that can
damage the plant power system
.
● Only qualified personnel should perform motor wiring.
● Never run a Sonic centrifugal blower with the discharge open to atmosphere
– such a situation leads to
motor overloading and motor damaging.
● The Sonic 350 blower must rotate counter clockwise (C
CW) when viewed from the sprocket end or
clockwise (CW) when viewed from the cooling fan end of the motor – see Fig.6 below.
