Using needle-nose pliers, gently grasp the pc board and pull it out and
from side to side to remove it from the module. -
3. Select the voltage.
There are four voltage selections, one written on each edge of the pc
board with a small arrow pointing to it.
a. Measure your facility outlet voltage, then rotate the pc board
until the edge with the measured voltage printed on it faces the
inside of the module (the arrow points into the module).
b. Move the white indicator pin in the pc board slot so it points
away from your selection and so it will protrude through the
correct hole in the cover plate when the plate is replaced in step 6.
4. Replace the voltage selector card.
Make sure the pc board seats properly for good electrical contact.
5. Verify the correct fuse is installed.
Remove the small screw holding the fuse block to the cover plate to
access the fuse. Use the table below to determine the correct fuse size
for your facility line voltage, then verify the correct one is installed.
I Line Voltage Fuse Value
100 to 120 Vac
1 A slow blow
220 to 240 V,
A slow blow
6. Snap the cover plate into place.
If the indicator pin is not in the correct position, repeat steps 3 and 4.
This completes the procedure for changing the voltage setting.
