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 af-
ter a channel failure. Examples of critical control functions include an emergency stop switch
(emergency stop) and overshoot stop.
•
Separate or redundant control channels must be provided for critical control functions.
•
Each implementation of a control system must be checked carefully and individually to ensure
faultless operation before the device is put into operation.
•
System control channels may include communication links. For this reason, the effects of un-
expected transmission delays and connection disruptions must be taken into account.
1)
Failure to follow these instructions can result in equipment damage, serious injury or death!
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 equipment damage or injury.
Caution!
RISK OF LOSS OF POWER DUE TO CAPACITOR WEAR
The performance of product-specific capacitors may be reduced after long-term storage of over 2
years.
In this case, the following measures must be undertaken before using this product:
•
Use a variable AC power supply that is connected between L1 and L2 (also for model numbers
8I74T40xxxx.01P-1).
•
Increase AC supply voltage to the following values:
– 25% of the rated voltage for 30 minutes
– 50% of the rated voltage for 30 minutes
– 75% of the rated voltage for 30 minutes
– 100% of the rated voltage for 30 minutes
Failure to observe these instructions can result in damage to the device.
