2.3 Installing the SCR/Diode Module Busbars
SCR/diode module conversion kits contain 3 SCRs plus new busbars. Use the following steps to install the busbars. See
Procedure
1.
Position the 3 SCR input busbars in the frequency converter, 1 on each SCR/diode module.
2.
Fasten 3 standoffs (19 mm), 1 in each SCR/diode module connecting it to the busbar.
3.
Fasten 3 M10 screws (T50) in the SCR-to-DC(-) busbar, connecting it to the 3 SCR/diode modules.
4.
Fasten 3 M10 screws (T50) in the SCR-to-DC(+) busbar, connecting it to the 3 SCR/diode modules.
5.
Position the DC(-) busbar behind the SCR-to-DC(-) busbar and fasten 1 screw connecting the busbars.
