6 Checklist
Always read the safety instructions prior to commissioning. Before starting for the first time, ensure that:
• The ambient temperature, humidity, dirt in the environment and the air’s corrosive properties have been taken into
consideration.
• The impeller do not hit parts of the fan housing.
• Installation and electrical wiring are carried out in a professional manner
• Safety equipment is installed
• Any installation debris and foreign objects are removed from the impeller and air intake area.
Warning
Loose objects inside the housing may be flung out!
• Protective conductor and external earth conductor are connected.
• Cable glands are sealed
• PTC resistors and tripping device is connected and fully functional.
• Connection data corresponds with the data on the rating plate: Max. voltage +6%, -10%, according to IEC 38. Rated
current/power must not be exceeded at rated voltage.
• The voltage is permitted to vary down to 80 V (1~) and 95 V (3~) with transformer.
• The motor cooling fan must have clearances of at least 40 mm (see figure 1.)
7 Commissioning
Commissioning may only take place if all safety instructions and controls according the checklist is performed without
comment. When putting into operations check that:
• No moving parts is touching the housing.
• The impeller direction of rotation is correct (direction arrow on housing, see figure 2).
• The motor runs smoothly without abnormal noise and that the operation is without vibrations. (Strong vibrations due
to imbalance, e.g. caused by transport damage or improper handling can lead to damage, check for imbalance as
necessary.)
• All electrical conducting components are grounding through contact washers.
• The fan is not controlled by extensive on and off regulation.
• The motor are intended for continuous operation S1. The control system cannot permit large numbers of switching.
• A-weighted sound pressure levels above 70 dB(A) can occur, see the product catalogue.
Note:
If the fan is stationary for longer than a week in a damp environment it must be in operation for at least 2
hours every week to remove any condensation in the motor.
