Installation guidelines

• If a mains filter is also installed, the mains choke is connected between the supply
and the mains filter. See the diagram below.
• For optimal operation of the choke, the drive and the choke must be mounted on
the same conductive surface.
• Ensure the choke does not block the airflow through the drive module, and that
the air rising from the choke is deflected away from the air inlet of the drive
module
• Keep the cable between the drive and the choke as short as possible.
WARNING! The surface of the mains choke becomes hot when in use.
