Selecting an AC Line Inductor –
IMPORTANT: A user supplied AC Line inductor must be installed
between the Line filter and the AC power input of the 1397 Drive.
The inductor provides the impedance required by the line filter, as
shown in Table B.A, B.B or B.C. This inductor also limits the SCR
line commutation notch to less than 80% when the Drive is
connected to a 5% to 6% impedance source. This meets the
requirements of DIN 160 Line Notching.
If the Drive is to be used in an overload condition, an inductor must
be chosen that is rated for the resulting average RMS current and that
will not saturate during overload.
Selecting an Operator Control Station – If an operator control
station is connected to the Drive, its enclosure must be conductive
metal. The enclosure cover must be bonded to an internal ground
point with a braided strap across the hinge. Standard industrial
operator devices, such as pushbuttons, switches and meters can be
used.
