Storage and Setup
Storage
The devices must be stored in a clean, dry space. The storage
temperature must be between –25 °C and +70
°C. Temperature
variations greater than 20 K per hour are not permitted.
Note: The converter and supply modules have AL electrolytic
capacitors as DC link capacitors. They can be stored for a
maximum of 2 years, not under power, at a storage
temperature of
≤
40 °C.
Minimum Requirements at the Installation Location
•
The operating area should be dust-free. Dust-laden air must be
filtered (3K3 acc. to DIN IEC 721-3-3).
•
The ambient temperature must lie between 0 and 40 °C.
•
The relative humidity may not exceed 90 %; condensation is not
permissible.
•
The supplied air must not contain any aggressive or electrically
conducting gases that may endanger functioning of the device.
•
The airflow of the fans may not be impeded. The minimum free
spaces specified for the supply air and exhaust air for each size class
must not be restricted by auxiliary add-ons.
•
The device causes power loss and heats the surroundings.
Therefore, a sufficient clearance from heat-sensitive devices must be
ensured.
Utilization
With mounting conditions diverging from those specified above, the
following rating data will be reduced in accordance with the diagrams (see
Fig. 5-6:
Utilization at a higher ambient temperature, Fig.: 5-7
Derating depending on setup elevation"):
•
Drive controller:
•
permissible DC bus continuous rating
•
braking resistor continuous rating
•
continuous current
•
Motor:
•
performance
•
continuous torque at standstill
•
S1 continuous torques
With deviating ambient temperatures together with higher setup
elevations, both utilization factors must be multiplied. Setup elevation is to
be considered only once. Deviating ambient temperatures are to be
considered separately for the motor and the drive controller.
