4.2.4 Losses
Losses are equivalent to 0.5% of Drive rated output across the range.
The following table lists the losses in kW and HP for all models, at 400 V
armature voltage.
The field rectifier is protected by fuses FS1, FS2, FS3 on the power
boards.
Before attempting to replace fuses FS1, FS2, FS3 the
supply voltages must be removed from the Drive and
left removed for at least 2 minutes.
4.2.5 Recommended Line Reactors
To avoid electrical interference and dI/dt stress, do not
operate without line reactors. The following table gives
typical values to achieve a notch depth of 50%. Where a
specific notch depth is required, values must be
calculated. Refer to IEC 61800-3 for details of
calculation of notching depth.
