Fuse Replacement

Remove the fuse holder from of its housing. Then take out the damaged fuse
from its holder and replace with exact same type of fuse. Reattach the fuse
holder, and then reconnect power.
Connecting A Bunch of Super-G™ 150 Fixtures
You will need a serial data link to run light shows using a DMX-512 controller
or to run shows on two or more fixtures set to sync in master/slave operating
mode. The combined number of channels required by all the fixtures on a serial
data link determines the number of fixtures the data link can support.
Fixtures on a serial data link must be daisy chained in one single line. Also, con-
necting more than 32 fixtures on one serial data link without the use of a DMX
optically-isolated splitter may result in deterioration of the digital DMX signal.
The maximum recommended cable-run distance is 500 meters (1640 ft). The
maximum recommended number of fixtures on a serial data link is 32 fixtures.
Data/DMX Cabling
To link fixtures together you'll need data cables. You should use data-grade
cables that can carry a high quality signal and are less prone to electromagnetic
interference.
For instance, Belden© 9841 meets the specifications for EIA RS-485 applica-
tions. Standard microphone cables will "probably" be OK, but note that they
cannot transmit DMX data as reliably over long distances. In any event, the
cable should have the following characteristics:
• 2-conductor twisted pair plus a shield
• Maximum capacitance between conductors – 30 pF/ft.
• Maximum capacitance between conductor & shield – 55 pF/ft.
• Maximum resistance of 20 ohms / 1000 ft.
• Nominal impedance 100 – 140 ohms

Before replacing a fuse, disconnect the power cord.
ALWAYS replace with the same type and rating of fuse.
