MULTI-MON
WARNING
Before installation ensure that all incoming power
sources are shut OFF. Failure to observe this
practice can result in serious or even fatal injury
and damage to equipment.
IMPORTANT
USE ONLY WITH SUPPLIED BFM CURRENT
TRANSFORMERS.
Connect the wires to the + and - inlets according to the
following polarity colors:
Solid Core Current
Polarity
Transformer secondary
+
RED
-
ORANGE
It is recommended to mark the cables and CTs with the
supplied tie markers.
CTs stickers I1 through I36 correspond to the Multi-Mon
current inputs with matching labels. Cable stickers 1 through
12 correspond to the Multi-Mon 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 CT 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 CT 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 Multi-Mon 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-
2
section 5.3 mm
(AWG10) at least.
The properly marked external 3-pole disconnect device with
circuit-breaker and a fuse 6 A, 600 V in every pole should be
installed between voltage measurement terminals and power
lines, located as close as possible (less than 2 m
recommended) to the Multi-Mon, as shown in figure 2-5.
