•
Do not use the module installation ramp with plinth heights which exceed the
maximum height (50 mm [1.97 in]) marked on the ramp.
•
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.
•
Keep the drive in its package or protect it otherwise from dust and burr from drilling
and grinding until you install it. Protect also the installed drive against dust and burr.
Electrically conductive debris inside the drive can cause damage or malfunction.
•
Vacuum clean the area below the drive before the start-up to prevent the drive cooling
fan from drawing the dust inside the drive.
•
Make sure that there is sufficient cooling. See section
on page 41.
•
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 the automatic fault reset or automatic restart 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 or supply break.
•
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. For the Safe torque off, see chapter
on page 179. For other safety functions, see their separate instructions.
•
Beware of the hot air flow from the air inlet.
•
Do not block the air inlet or outlet when the drive is running.
