Figure 2-6 Single HACS wiring and labeling
USE ONLY WITH SUPPLIED BFM CURRENT TRANSFORMERS!
Connect the wires to the + and - inlets according to the following polarity
colors:
Polarity Solid Core HACS secondary Split Core HACS secondary
+ RED WHITE
- ORANGE BLACK
It is recommended to mark the cables and CTs with the supplied tie markers.
HACS stickers I1 through I36 correspond to the BFM136 current inputs with
matching labels. Cable stickers 1 through 12 correspond to the BFM136
current terminal blocks with matching labels.
Use the table from Appendix B to annotate your input assignments and
wiring connections.
Labeling example:
Assume you want to connect three HACSs to the device terminal block 3 so
these three HACSs would be connected to the device inputs I7, I8, and I9
respectively:
1. Take a HACS connection cable, attach a tie wrap marker to each side of
the cable and mark them as 3 to indicate that it should be connected to
the device terminal block 3.
2. Put the HACS label stickers I7, I8, and I9 directly on HACSs to indicate
that these HACSs will be associated with the device current terminals I7,
I8, and I9.
Safety Requirements
To ensure safety requirements the BFM136 must be grounded - the
protective ground terminal should be connected to protective earth with a
copper conductor or strap with minimal length (less than 1 m desirable) and
cross-section 5.3 mm
2 (AWG10) at least.
