Prerequisites
For a complete SED2 IP21 installation, the following items are required, depending on frame size:
Frame size
SED2 AC 200...240 V
3 phases / IP20
A
SED2-0.37/22(B/X)...SED2-0.75/22(B/X) SED2-0.37/32(B/X)...SED2-1.5/32(B/X)
B
SED2-1.1/22(B/X)...SED2-2.2/22(B/X)
C
SED2-3/22(B/X)...SED2-7.5/22(B/X)
Mounting notes
•
To ensure correct mounting of the SED2 variable speed drive and the IP21 cover, read these instructions carefully
before starting the installation
•
Use the SED2-IP21 cover only when mounting the SED2 on a wall, to increase the degree of protection of the
equipment from IP20 to IP21
•
Mount the equipment in a clean, dry and lockable room
•
Do not install the SED2 with IP21 cover in a space open to the public
•
Mount the SED2, and especially the IP21 cover above it, on a flat wall
•
Mount the SED2-IP21 cover strictly according to these instructions and the drilling plans shown for frame sizes A...C,
thus ensuring that the standards for degree of protection IP21 and protection against electric shock (EN 60529) will be
met and that the SED2 will safely operate
Mounting and mains connection
1. Mark the boreholes for the SED2 and the IP21 cover on a flat wall according to the drilling plans shown below.
2. Drill the holes according to the fixing screws listed below and fit the SED2 including the EMC footprint filter to the wall.
We recommend to use the following mounting material:
Frame size
SED2 complete with EMC
footprint filter / IP21 cover
SED2
A
SED2-IP21-A
SED2
B
SED2-IP21-B
SED2
C
SED2-IP21-C
3. Connect the power supply cable to the SED2 or the EMC footprint filter underneath.
Strip the jacket of the power supply cable as close as possible to the connection
terminals of the SED2 (refer to the illustration at top right). After mounting the IP21
cover, it must under no circumstances be possible to touch the basic insulation. Tension
relief of the power supply cable must be provided on site.
Note:
If possible, do not drill any additional holes in the IP21 cover. If there is a
need to introduce the power supply cable through the IP21 cover, use a
cable entry gland with rubber seal, ensuring degree of protection IP21 as a
minimum requirement.
Also observe the SED2 Commissioning Guide (CM1G5192en), chapter 4
EMC-compatible installation of SED2 and, especially subsection 4.4.1
Potential equalization and earthing.
4. Fit the IP21 cover
Note:
If a flat wall is not available for fitting the IP21 cover, use a sealing band
between the wall and the cover to ensure that condensation, if any, cannot
penetrate the SED2.
