- For altitudes up to 1000 meters above sea level.
For operating temperatures above +40ºC and up to +80ºC, the correction factors
indicated in the table below, must be applied to the nominal motor power rating in
order to determine the derated available output (Pmax).
Pmax = Pnom x correction factor
Ambient temperature (ºC).
Correction factors to
derating the output power
of the motor
For altitudes higher than 1000 meters above sea level, a correction factor for altitudes
must be applied too, in order to determine the derated output (Pmax). The factory
must be consulted to indicated the correction factor to be applied.
5.9 Ensure that the air inlet and outlet opening are not blocked. The minimum clearance to
the nearest wall shall be at least ¼ of the fan cover diameter. The intake air
temperature must be at ambient temperature, limited to the temperature range
indicated on the nameplate of the motor (if not indicated, consider -20ºC to +40ºC).
5.10 To prevent accidents, check if motor has been solidly grounded in accordance with
the applicable standards. Remove or fix the shaft key before starting the motor.
5.11 Connect the motor properly to the power supply by means of safe and permanent
contacts, always observing the data on the nameplate, such as rated voltage,
connection diagram, etc.
5.12 When terminal is used, all wires that form the multi-wire cable must be stuck inside
the sleeve. The non-isolated part of the accessory cables shall not exceed 1 mm up to
the connector.
6. START UP
6.1 If the motor has been out of service or stored for a long period of time, it is
recommended that the winding resistance is measured before installation and start up.
