Warning!
CONTROL FAILURE
•
The designer of any wiring scheme must consider the potential failure modes of control chan-
nels and, for certain critical functions, provide a means to achieve a safe state during and after
a channel failure. Examples of critical control functions: Emergency stop and stopping in the
case of an overrun traverse that is too long.
•
Separate or redundant control channels must be provided for critical control functions.
•
System control channels may include communication links. The effects of unexpected trans-
mission delays or failures must be taken into account.
1)
Failure to follow these instructions can result in death, serious injury or material damages.
1) For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety guidelines for the application, installa-
tion and maintenance of solid state control" and to NEMA ICS 7.1 (latest edition), "Safety standards for construction
and guide for selection, installation and operation of adjustable-speed drive systems."
Caution!
INCOMPATIBLE MAINS VOLTAGE
Before switching on and configuring the frequency inverter, ensure that the mains voltage is compat-
ible with the supply voltage shown on the frequency inverter nameplate. The frequency inverter may
be damaged if the mains voltage is not compatible.
Failure to follow these instructions can result in injury or equipment damage.
Caution!
IMPROPER OPERATION OF THE INVERTER
•
If the inverter has not been turned on over a longer period of time, the performance of the
electrolytic capacitors is reduced.
•
If the inverter remains out of operation for a longer period, switch it on every 2 years for at
least 5 hours to reestablish the performance of the capacitors. Then check the operation of the
inverter. It is recommended not to connect the inverter directly to the mains voltage, but rather
to increase the voltage gradually with the aid of an adjustable AC voltage source.
Failure to follow these instructions can result in injury and/or equipment damage.
