7.5.2 COMPAX 25XXS-specific technical data
!
Energy recuperated during braking is stored in the supply capacitors. The
capacity and storable energy is:

If the recuperated energy causes overvoltage, then external ballast resistances can
be engaged.

We can supply external ballast resistances for COMPAX 25XXS
(see Page 193).
Connecting ballast resistance to COMPAX-S
The ballast resistance is connected to B+, B- and, if necessary, PE.
Output X4 is protected from short circuits.
Mating connectors for X1,..X4 from Phoenix are included with the following type
designations:
X1: MSTB2.5/8/STF-5.08 (with screw connection)
X2: MSTB2.5/4/ST-5.08 (without screw connection)
X3: MSTB2.5/2/ST-5.08 (without screw connection)
X4: MSTB2.5/3/STF-5.08 (with screw connection)
You can acquire Phoenix housings for these connectors and these can be used
once adapted to our cables. Designation: KGG-MSTB2.5/(pin number).
