General Information

For default operation no additional equipment is required. However, for
more complex operation either the Basic Operator Panel (BOP),
Advanced Operator Panel (AOP) or Fieldbus options can be used.
These are available as non-standard options and must be ordered
separately.
When delivered the inverter has a frequency setpoint range of
between 0 Hz and 50 Hz. Regardless of its initial position the Control
Potentiometer must be turned fully counter-clockwise before the
inverter can start.
WARNING
The inverter does not have a mains power switch and is therefore live
when the power supply is connected.
