Setting the Line Voltage Switch
The line voltage switch, which is part of the power connector on the
Model 3955 electronics module, must match your local line voltage. The
Model 3955 and optional Model 3930 are shipped from the factory with
the line voltage selected for the location of intended use. If the incorrect
setting is selected, you must change it prior to applying power to the
system. The following directions are provided so you can make the change
yourself.
1. Remove the cover platelfuse block assembly to expose the voltage
selector card. Refer to Figure C-1.
Use a small screwdriver to gently pry off the cover plate. A slot is
provided for screwdriver access.
