Figure 1. Power Input Module
The power module contains the voltage selector drum, fuses and the power cord
connector. The appropriate voltage setting is set at the factory and can be seen on the
back of the power module.
Each setting actually defines a range and you should select the setting that is closest to
the actual line voltage. The fuse and power requirements are printed on the panel above
the power module. As shown in Figure 1, the Power Module contains two fuses. The two
fuses are of different values and both change according to the value of the selected line
voltage as indicated on the back panel.
The correct fuses for the country where the
ST-133 or ST-133A is to be shipped are installed at the factory.
Be sure to use the proper fuse values and types for the controller and camera to be
properly protected.
To change the line-voltage setting or replace a fuse, proceed as follows.
Before opening the power module, be sure to unplug the line cord.
1. Take a flat blade screwdriver, place the flat side parallel to the back of the controller
and pointing downward behind the small tab at the top of the power module, and
twist the screwdriver slowly but firmly to pop the module open. See Figure 1.
2. To change the voltage setting, roll the selector drum until the appropriate voltage
setting is facing outwards.
