2. On the transformer (F), move the BROWN wire to the terminal listed for your voltage. The terminal numbers
are printed in front of the connection tabs.
3. On the ballast (E), move the BROWN wire to the terminal listed for your voltage and frequency.
4. Replace the cover.

Fixtures wired for 100 or 120 volt operation shall have a 10 ampere main fuse
(P/N 05020025). Replace this with a 6.3 ampere fuse (P/N 05020020) if rewiring

1. Make sure the RoboScan Pro 918 is isolated from AC power. Access the trans-
former and ballast as described above.
2. Find the correct transformer setting for your AC supply in the table above. The
colors refer to the wires that enter the connection block at the bottom. The figure
to right shows the transformer connection block as seen from the top. On the
transformer (F), move the BROWN wire to the correct terminal.
3. On the ballast (E), move the BROWN wire to terminal 7 (60 Hz), or terminal 10
(50 Hz). The other terminals are not used because the ballast is fed 230 volts
from the transformer.
4. Replace the cover.
