Lifting the AC drive
The AC drive is delivered horizontally in a cardboard box or on a wooden pallet. Open the package
only when you install the drive. Do not keep the drive in storage in the vertical position.
3.3.1
Weight of the AC drive
The weights of AC drives of different enclosure sizes are different. It can be necessary for you to use
a lifting device to move the drive from its package. See the weights of the different enclosure sizes
in below table.
The terminals are live
when the drive is connected to a photovoltaic system.
Photo-
voltaic cells generate DC voltage even at low intensity of sunlight.
Wait 60 seconds
until the drive is discharged,
before switching between AC and DC
supply
(photovoltaic system) and vice versa.
Do not remove the EMC screws in the solar pump application. IT (impedance-
grounded) AC supply network is not allowed in the solar pump application.
LIFTING HEAVY LOAD
Not following the safe lifting instructions can result in death or serious injury.
•
Do not walk under suspended loads.
•
Use lifting devices that are appropriate for the weight of the unit.
•
Use the recommended lifting method.
