Cooling Unit - Siemens Sinamics S120 Function Manual

Fast DC link discharge (booksize)
It is only possible to quickly discharge the DC link via the Braking Module for the booksize
format. It is activated via binector input p3863 and started after the line contactor opens and
the adjustable delay time (p3862) has expired. The fast discharge is completed when the line
contactor contact closes.
NOTICE
A fast DC link discharge requires the use of a line contactor with feedback signal (p0860)
that is controlled via r0863.1.
