FREQUENCY INVERTER

The shielded cable must be led either through an EMC approved cable

gland in the casing of the frequency inverter or through a cap intended for

this purpose.

The shielded cable must not be connected to an earth screw.

The shield must be in 360º

contact with

the casing

NOTE!

PARAMETERS

Speed controller parameters are set at the factory pro-viding for

optimal performance of fan and motor. This includes motor para-

meters, ramp times, starting and stopping methods and speed

limitations.

Changing of these parameters may result in unstable

operation or motor won’t start.

GENERAL

• Admissible environmental temperature: from -15 °C up to

+40 °C, with altitudes 1000 m above sea level

• Mounting: IM B3, B5

• Drive operating voltage: 400 VAC

• Insulation class: "F"; temperature rise to class B

(TEFC execution)

• IP55 degree of protection for the whole range

• Reduced dimensions

• Rare earth permanent magnets

NOTE!

The frequency converter have been optimized for the

duty point. The power could thus be lower than the

motors rated power.

PM-MOTOR

INSTALLATION

A continuous, shielded 4-wire cable designed for EMC installation to

motor drives should be installed between the motor and the frequency

inverter. The optical density of the cable shield shall be at least 80 %, e.g.

NCY or Olflex Classic. The shield must be in 360 º contact with the casing

both in the motor and in the frequency inverter in order to achieve maxi-

mal surface contact. It is not advisable to install a safety isolating switch

or junction boxes between the frequency inverter and the motor.

INSTALLATION

WARNING!

The motor is designed exclusively for operation with

the supplied speed control (frequency converter).

Direct on-line connection to the mains is not possible

for PM-motors.

WARNING!

Risk of electric shock:

Motor terminals may still be live if the impeller is

rotating, even when the main incoming supplied has

been isolated. Ensure the impeller is kept stationary

before opening and whilst the terminal box is open.

MOTOR

The cable must be led into the terminal box of the motor through an

EMC approved cable gland, e.g. through a Miltronic SKINTOPMS-SC. The

shielded cable must only be connected via the EMC cable gland, not to an

earth screw.

OTHER DETAILS

In addition to the above, observe the following:

• type of mains power supply

• local electrical safety rules and regulations

• manufacturer’s installation instructions for the frequency inverter.

The shield must be in 360º

contact with the casing Casing
