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 D…F,
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
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:

3. 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.
Also observe the SED2 Commissioning Guide (CM1G5192en), chapter 4 EMC-compatible installation of
SED2 and, especially subsection 4.4.1 Potential equalization and earthing.
