Installation procedure
Risk of electric shock when the connection box lid is open. Make sure that the electric device is discharged; measure the
voltage to make sure of safety.
Heavy electric device. Handle with care. Handle the electric device correctly when you install it to the correct mounting
position. See chapter
Measure the insulation resistance of the electric device before and after the installation of the electric device.
When installing the connection box lid, make sure there are no foreign particles between the connection box lid and the
insulation and that all connection box fasteners are in place. Missing or loose screws can compromise the insulation.
Preparations
Make sure that the chosen installation place ful lls the environmental requirements speci ed
for the electric device.
Protect the electric device against corrosive gases, liquids, conductive contaminants (such as
condensation, carbon dust, and metallic particles) and sprays or splashing water from all
directions.
Protect the electric device in high humidity, salty or chemical content environments with
suitable additional enclosure.
The mounting place and mounting interfaces should be sufficient to carry the weight of the
electric device.
Make sure that the electric device has sufficient mounting and operating clearances for
maintenance work.
Installation procedure may vary from that shown in this user guide. All steps must be included
in the procedure, although the order of the steps can be different.
Installation procedure
1. Prepare the installation place and make sure that it meets the requirements for the product.
2. Lift and support the electrical device for the mounting. Refer to Chapter
3. Install all appropriate mounting screws, do not tighten the screws until they are aligned and
pre-installed. See the tightening torques from Chapter
4. Connect the cooling system. See chapter
for connection details. Make sure that there are no air pockets in the cooling channels and that the
coolant goes freely in and out. Make sure that the cooling system operates correctly.
5. Make sure that the devices and machines you will connect to the electric device have no
voltage.
6. Make the grounding of the frame of the electric device by direct contact between it and the
metal bracket and / or from the protective earth contacts. The grounding contacts must be paint-
free. See Chapter
