Connecting auxiliary power to the diode supply module
The cabinet builder can arrange an auxiliary AC power supply of 230 V AC (or 115 V AC
with option +G304) to connector X50 to power the electronics of each supply module.
There is an internal power supply (BDPS) in the module that produces 24 V DC from the
auxiliary voltage for the internal circuit boards.
If a direct-on-line fan (option +C188) is used, the user must connect the fan supply to the
module control connector X50. The optional heating element (D8T option +C183) also
requires external AC power supply to the module control connector X50.
For connectors X50, see
Connectors X50 and X53 of D8T supply module
The plug connector is available from ABB. See section
supply modules
on page 188. See also section
on page 224.
