Warning!
The drive controller contains dangerous voltages and controls potentially
dangerous rotating mechanical parts. The installation, commissioning and
maintenance of this equipment should be performed only by qualified personnel
who are familiar with the operation. The installation, commissioning and
maintenance of this equipment should be performed only by qualified personnel
who are familiar with the operation.
Do you have particular caution if the automatic restart is activated? To avoid injury
by possibly unintentional restart of the drive controller after a power failure, turn
off the automatic restart in case of doubt. When repairing or servicing this
equipment, make sure that the system cannot be switched on by others again!
The frequency controller has DC link capacitors, which carry hazardous voltage
even after the mains supply is switched off.
Therefore, always wait after switching off the mains voltage for at least 5 minutes
before working on the machine or turn on the unit again. It is important to ensure
that no live parts are touched when power is applied or the intermediate circuit
capacitors are charged.
Do not work on the wiring and check any signals when power is applied. The
Inverter - Regulator has a leakage current. Ground the frequency controller on the
connections provided.
3.2
Caution!
All frequency controllers are tested for dielectric strength and insulation
resistance. Before the insulation measurement in the pump station, for example
within the scope of the inspection frequency controller must be disconnected! It is
strongly recommended that all electrical equipment conforms to the National
Electrical Codes and local regulations.
Factors such as high temperatures, high humidity as well as dust, dirt and
corrosive gases.
The installation should be a well-ventilated, not exposed to direct sunlight place.
Put them no mains voltage to the transducer terminals or to the control terminals.
Enter the operating signals Hand/0/Auto via the selector switch on or about the
driving of external contacts and not by switching on and off of a line or motor
contactor. Only qualified personnel should perform installation, alignment and
maintenance.
The manufacturer reserves the right to alter the technical data in order to make
improvements or update information.
The manufacturer cannot release you from the obligation to comply with the latest
safety standards the user.
