•
Do not use the module installation ramp with plinth heights which exceed the
maximum height marked on the ramp. (The maximum plinth height is 50 mm
[1.97 in] when the telescopic ramp is fully retracted and 150 mm [5.91 in] when
the ramp is fully extended.)
•
Secure the module installation ramp carefully.
•
To prevent the drive module from falling, attach its top lifting lugs with chains to the
cabinet lifting lug before you push the module into the cabinet and pull it from the
cabinet. Work carefully preferably with help from another person as shown below.
Keep a constant pressure with one foot on the base of the module to prevent the
module from falling on its back.
•
Beware of hot surfaces. Some parts, such as heatsinks of power semiconductors,
remain hot for a while after disconnection of the electrical supply.
•
Make sure that debris from borings and grindings does not enter the drive during the
installation. Electrically conductive debris inside the drive may cause damage or
malfunction.
•
Make sure that there is sufficient cooling. See section
on page 53.
•
Before you connect voltage to the drive, make sure that the cabinet doors are closed.
Keep the doors closed during the operation.
•
Before you adjust the drive operation limits, make sure that the motor and all driven
equipment can operate throughout the set operation limits.
•
Before you activate automatic fault reset functions of the drive control program make
sure that no dangerous situations can occur. These functions reset the drive
automatically and continue operation after a fault.
•
The maximum number of drive power-ups is five in ten minutes. Too frequent power-
ups can damage the charging circuit of the DC capacitors.
•
Make sure that any safety circuits (for example, emergency stop and Safe torque off)
are validated in start-up. See chapter
instructions.
