Further data which is not listed here can be obtained from the manual for the basic device (BU0200).
10.1 Environmental data
Function Specification
Ambient temperature -25 °C…to +40 °C (+50 °C in S3 operation)
Note: The derating specifications (power, current, duration of switch-on)
depending on the type of inverter and the cooling conditions must be taken
into consideration. (see Manual BU 0200 GB)
Storage temperature -25 °C ... +60 °C
transport temperature -25 °C ... +70 °C
Climate class 3k3 (3K4 for IP66 devices)
Installation altitude above sea level ≤ 2,000 m
Excess voltage category 3
Degree of fouling 3
Protection class
for motor mounting
IP55 (IP66 can be ordered as an option),
for motor mounting, this depends on the motor
Protection class
for mounting with wall bracket
IP55 or IP66 (optional) depending on the inverter
Long-term storage After one year at the latest, the frequency inverter must be connected to the
mains supply for 60 minutes. In addition, the "safe pulse block" and the 24 V
supply must be provided with voltage (24 V) or operated in the
commissioning configuration. This cycle must be maintained for the storage
period.
EMC When using wiring that conforms to EMC requirements, as per BU 0200 GB,
the limiting values can be complied with up to a line length of 100 m between
the protective switching device and the inverter.
