Connect the 8720MC-RPS Unit Chapter 5
Install the Harmonic Filter (8720MC-RPS065 units only)
Install the 8720MC-HF-B2 harmonic filter to remove high-order harmonics
generated by the switching operation of the AC input power modules. Wire
size for the 8720MC-HF-B2 harmonic filter is 3.5 mm
2
(12 AWG).
Install the EMC Line Filter (8720MC-RPS065 units only)
An AC (EMC) line filter is required for meeting the requirements of CE.
Install a line filter for three-phase AC input power and single-phase AC power
for the main magnetic contactors. Line filters are used in power supply and
power regeneration configurations.
Table 23 - Line Filters for 8720MC-RPS065 Units
Install the Line Filter (8720MC-RPS190 units only)
The 8720MC-EF190-VB (EMC) line filter unit contains line filter, magnetic
contactor, varistor, harmonic filter, and is used with the
8720MC-RPS190BM and 8720MC-RPS190BS regenerative power supplies.
Because the 8720MC-EF190-VB unit is completely assembled, the wiring can
be simplified in combination with 8720MC-LR10-100B reactors. For wiring
the 8720MC-EF190-VB unit, refer to
Figure 25 , Figure 26 , and Figure 27 .
Table 24 - Recommended Power Wire Sizes
IMPORTANT Connect the harmonic filter on the incoming AC line-side of the AC
contactor.
