5.3.2 DC Connection Configurations
CAUTION!
A tie bar is only recommended for single feed installations. The use of a tie bar in a two
feed installation can cause current loops.
If the system is equipped with optional rectifiers, each rectifier shelf in a hybrid system is only connected to
one of the DC- battery feeds:
• Top rectifier shelf to DC1
• Bottom rectifier shelf to DC4
In a system with four independent battery feeds, two of these battery banks will not be charged from the
AMPS80 HP rectifiers. When using two independent A/B feeds, DC1 should be tied to DC2 and DC3 tied to
DC4 at the AMPS80 HP DC connection points. Tie bars are provided.
