4  PREPARING THE PRODUCT FOR USE 
4.1  Transport and storage 
The product shall be stored in an environment meeting the following conditions: 
  storing temperature between -40 and +70 degrees Celsius 
  relative humidity below 95%, no condensation 
After unpacking the component, ensure that there are no visible signs of transport damage. 
4.2  Safety precautions before installation 
Before installing, check that there are no signs of damage on the frequency converter. 
DANGER 
THE ELECTRICAL INSTALLATION SHALL BE PERFORMED ONLY BY 
PERSONNEL AUTHORIZED BY THE MANUFACTURER. IT IS POSSIBLE THAT 
INSTALLATIONS MADE BY UNAUTHORISED PERSONNEL ARE INCORRECT, 
AND CARRY AN INCREASED RISK OF AN ELECTRICAL SHOCK. 
DANGER 
TO REDUCE THE RISK OF ELECTRICAL SHOCK, THE FREQUENCY 
CONVERTER SHALL ALWAYS BE GROUNDED WITH A GROUNDING 
CONDUCTOR CONNECTED TO THE GROUNDING TERMINAL. 
DANGER 
THE FREQUENCY CONVERTER’S POWER UNIT COMPONENTS ARE LIVE 
WHEN THE CONVERTER IS CONNECTED TO MAINS. THE VOLTAGE IS 
DANGEROUS, AND DIRECT CONTACT WITH IT MAY CAUSE DEATH OR 
SERIOUS INJURY. 
WARNING 
The frequency converter remains live while running a motor energized by a 
process. The motor acts as a generator that feeds energy to the frequency 
converter, creating a risk of an electrical shock. 
CAUTION 
The cover of the frequency converter shall not be opened. The converter’s 
components may be damaged by a static voltage discharge from, for example, 
fingers.
