Page 11: Connection To Power Mains
CONNECTION TO POWER MAINS DISCONNECT THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER CAREFUL READING OF THE PRESENT USER’S MANUAL. - Page 12 ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS There are several methods for starting asynchronous squirrel-cage electric motors. The most common methods are: direct-on-line (DOL), with a soft starter (SS) or with a frequency converter (FC). Direct-on-line starting In case of direct-on-line starting (i.e. by connecting the motor to the electric mains with a simple line contactor), the motor starting time significantly increases due to high inertia of the impeller, which, in turn, results in high in-rush starting currents in the circuit.

Page 13: Commissioning
Problems associated with DOL starting The problems caused by DOL starting may be divided into two groups: An abrupt start causes mechanical shock, jolts in the mechanism, shock removal of free play etc. A heavy start cannot be completed. Let us review three variations of a heavy start: 1. -

TECHNICAL MAINTENANCE DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS! PRIOR TO COMMENCING ANY TECHNICAL MAINTENANCE PUT UP A PROHIBITORY SIGN ON THE FAN STARTING PANEL: “DO NOT SWITCH ON! MEN AT WORK!” AVOID LIQUID SPILLS ON THE MOTOR! DO NOT USE AGGRESSIVE SOLVENTS AND SHARP OBJECTS FOR CLEANING! Prior to performing any technical maintenance and repair disconnect the fan from the electric mains and wait until its rotating parts come to a complete stop. - Page 15 The fan fails to reach the Fan motor overloaded. Eliminate the overload. required rotation speed due to Improper fan starting method.
