2.9 Employment of external personnel
Maintenance and service work are frequently carried out by external employees who often do not
recognize the specific situations and the thus resulting dangers.These persons must be comprehen-
sively informed about the hazards in their area of activity.
You must monitor their working methods in order to intervene in good time if necessary.
3 Product overview
3.1 Scope of application
Frequency inverter designed for speed control of fans without additional (electromagnetic) motor
noise.
By using the integrated all-pole effective Sine filter (phase to phase and phase to ground), an absolute
parallel control of fans without risk of damage for motors is possible. Screened motor cables not
required!
Only suitable for drives with low set-off torque (e.g.: fans or pumps).
3.2 Functional description
The frequency inverters generate their 3~ output with variable voltage and frequency from the three-
phase mains on the input.
The devices are constructed in accordance with the general requirement in EN 61800-2 for adjustable
speed electrical power systems and is intended for one-quadrantdrives.
The output frequency is set by an external signal (0 - 10 V, 0 - 20 mA, PWM).
