is factory wired for 277 volt supply then see “Adjusting power on 277 volt

models” on page 73.

Warning! Disconnect the fixture from AC power before removing any

cover.

1. Make sure the Exterior 600 is isolated from AC power and has cooled

for at least 20 minutes.

2. Remove the 10 Allen screws from the

rear cover plate. Carefully remove the

plate and seal.

3. Find the row in the above table with the

local AC frequency and voltage. Follow

the row to the right to find the correct

transformer and ballast tappings. For

example, with a local AC supply of 230V,

50 Hz, the correct transformer tapping is terminal 6 and the correct

ballast tapping is terminal 10.

4. To tap the transformer, move the 2 BROWN wires to the correct

terminal. Terminals are identified on the transformer in front of the

connection tabs.

5. To tap the ballast, move the single BROWN wire to the correct terminal.

6. Check the condition of the cover plate seal. Replace with a new one

(P/N 20600020) if the seal is torn, cracked or brittle.

7. Insert the Allen screws through all holes in the cover and the seal. Place

the cover firmly against the body.
