Storage
NOTICE
Long storage time.
Risk of damage to the variable-frequency drive!
Due to a long storage time the capacitors of the variable-frequency drive can lose effi-
ciency because of electrochemical processes. In worst case it can lead to a short circuit
and therefore to a damage to the variable-frequency drive.
• Connect the variable-frequency drive every 2 years for 30 minutes to the mains.
• Store the motor with the variable-frequency drive indoor, dry, dust free and if possible
in the original packaging preferably at temperature between -20 … 60 °C.
