The physical connections on the BML unit are listed
below, together with a simple explanation of their
purpose.
All connectors in the BML unit are keyed to prevent
wrong cable connections.
•
A
is the 6-pin connector that feeds -48 VDC to
the batteries in the battery cabinet or the
integrated battery unit.
•
B
is the output of the alarm relay inside the BML
unit. Its contact will close when the AC power
drops out then indicating that the system is
running on battery back up.

are the -48 VDC outputs that feed the
exchange cabinets.
•
N
is an IEC 320 C13 (17) input connector for the
220 VAC or 115 VAC mains. This input has a
mechanical locking for the power cord to prevent
it from slipping off.
•
F1
and
F2
are the fuses for the outputs
C
and
D
.
•
F
is a label stating the fuse ratings in the power
supply unit.
The
integrated battery unit provides the additional
connections:
•
H
and
I
for the alarm cables.
•
