H - CE-CONFORMITY
H-2 FlexPak 3000 49'1340 e
Essential Requirements for Conforming Installation
The following items are required for CE conformance:
1. Connection of EMC filter (RFI-Filter on drives <100 A or HF filter on drives >100 A) as specified in
Chapter 8, Accessories.
2. Because FlexPak 3000 and filter have protection class IP00 they must be built in a cabinet.
Both units must be mounted on a blank (not painted) panel with good conductivity.
3. Correct grounding of the equipment and the cable screens as shown in example Figure H-1.
4. Output power wiring (drive to motor) must be screened cable or run in a separate steel conduit.
5. All control (I/O) and signal wiring must be screened cable.
6. The braid of screened cables must be connected to the terminal box of the motor by the use of
suitable, EMC-tested cable glands.
7. For all DC-converters a minimum line reactor of 2% voltage drop will be required.
The line reactors must be linked between filter (Output) and DC-Converter (Input).
For line reactor selection refer to Table 8.9.
Mounting Instructions
(Refer to Figure H-1)
• The filters must be screwed directly to the panel with the largest possible contact area.
• The support panel for the converters and filters must be a conducting steel sheet, with a common
ground busbar at the bottom. This ground busbar, mounted in front of the terminals, must be
solidly connected to the panel, ensuring good conductivity.
• All cable screens, entering the cabinet, must be connected to the control cabinets ground busbar.
To ensure that the screen of the individual cable is connected solidly and with good conductivity to
the ground busbar, galvanised cable brackets as shown in Figure H-1 are recommended.
This applies also for coaxial cable, at which only the outer insulation should be removed.
Cable Glands
• Use suitable EMC-tested cable glands only
• The conductivity of the screen ground connection is ensured by laying the braid over a plastic cone
which will press it to the inner side of the gland when mounted. It is important that the connection
area is 360 degree around the cone. The cable glands provide pull-relief through the cable jacket.
