5.
If the direction of rotation is wrong, reverse the polarity of the motor
having due regard to the safety instructions.
6.
Once operating speed has been reached measure the current
consumption and compare it with the nominal motor current on the fan
type plate or motor rating plate
7.
If there is continuous overload switch the fan off immediately.
8.
Check that the fan runs smoothly and quietly. Ensure that there are no
unusual oscillations or vibrations.
9.
Check the motor for any abnormal noises.

Commissioning
The motors are designed for continuous operation S1. If operations involve
more than three starts per hour Nicotra Gebhardt GmbH shall be required to
confirm the suitability of the motor.
DANGER!
Potentially explosive gas mixtures in conjunction with hot and moving
parts may cause serious or fatal injury.
Risk of explosion due to increased ambient temperature!
1.
Observe ambient temperature.
2.
Ensure adequate supply of cooling air.
9.1. Conditions for Commissioning in Ex-Area
The following requirements must be met before operating the fan in areas
subject to explosion hazards:
Specifications on the type plate to meet the standards required in the
local operating conditions in respect of explosion hazards (device group,
explosion hazard category (hazard zone), gas group, temperature class).
All the components connected to the fan carrying a risk of ignition or
explosion to have the required approval certificates.
The ambient temperature during subsequent use to be within in the
allowed limits!
All the requisite safety devices to be installed.
Prevent impeller from contact and from being hit by falling or sucked-in
objects.
The fan is not operated in a dusty environment.
Ensure that unacceptable levels of dust are not allowed to gather on the
fan. (Note maintenance instructions.)
The distances from the impeller to the plant parts on site are checked and
meet the requirements for explosion protection.
Ensure that the fan is earthed in accordance with regulations.
9.2. Commissioning the Centrifugal Fan
DANGER!
Risk of injury from rotating parts and hot surfaces!
1.
Ensure that all the safety devices are fitted.
2.
Ensure that the impeller has been secured acc. to EN ISO 13857!
