WARNING!
•
Make sure that dust from drilling does not enter the drive when installing.
Electrically conductive dust inside the unit may cause damage or lead to
malfunction.
•
Fastening the cabinet by riveting or welding is not recommended. However, if
the cabinet is fastened by welding, connecting the return wire improperly may
damage electronic circuits in the cabinet. Ensure that welding fumes are not
inhaled.
•
Ensure sufficient cooling. If the drive is equipped with a double roof, ensure that
the roof is lifted up from the transportation position to enable the cooling air flow
before starting the drive.
Air flow from below (from a cable conduit) to the cabinet must be prevented to
ensure the degree of protection and fire protection.
•
Cooling fans may continue to rotate for a while after the disconnection of the
electrical supply.
•
Some parts inside the drive cabinet, such as heatsinks of power
semiconductors, remain hot for a while after the disconnection of the electrical
supply.
WARNING!
•
The printed circuit boards contain components sensitive to electrostatic
discharge. Wear a grounding wrist band when handling the boards. Do not
touch the boards unnecessarily.
