Wiring to an EcoSystem Bus Supply
•
The bus supply does not have to be
located at the end of the EcoSystem bus
•
E1 and E2 wires are polarity insensitive
•
Bus length is limited by the wire gauge
used for E1 and E2 as follows:
Wire Gauge
Max Loop Length
#12 AWG (2.05mm)
2,200' (670m)
#14 AWG (1.63mm)
1,400' (426m)
#16 AWG (1.29mm)
900' (274m)
#18 AWG (1.02mm)
550' (167m)
Attention Electricians and Contractors
Regardless of bus wire gauge, ballast and
BMF terminals will hold only one
#16 to #18 AWG solid wire. In most cases
a wire connection to the EcoSystem bus
is required.
Note: Two different color wires are
recommended for the EcoSystem bus.
This prevents accidentally creating
a loop circuit with one wire.
