22 MicroMAX System User Manual Version 5.A
Power Requirements
The MicroMAX system can operate from any one of four different nominal line voltages,
100, 120, 220, or 240 V AC. The power consumption is nominally 200 watts and the line
frequency can range from 47 to 63 Hz.
The MicroMAX camera receives its power from the controller, which in turn plugs into a
source of AC power. The plug on the line cord supplied with the system should be
compatible with the line-voltage outlets in common use in the region to which the system
is shipped. If the line cord plug is incompatible, a compatible plug should be installed,
taking care to maintain the proper polarity to protect the equipment and assure user
safety.
Verifying Controller Voltage Setting
The Power Input Module on the rear of the Controller contains the voltage selector drum,
fuses and the powercord connector. The appropriate voltage setting is set at the factory
and can be seen on the power input module.
Each setting actually defines a range and the setting that is closest to the actual line
voltage should have been selected. The fuse and power requirements are printed on the
panel above the power input module.
The correct fuses for the country where the
ST-133A is to be shipped are installed at the factory.
To Check the Controller's Voltage Setting:
1. Look at the lower righthand corner on the rear of the
Controller. The current voltage setting (100, 120, 220,
or 240 VAC) is displayed on the Power Input Module.
2. If the setting is correct, continue with the installation.
If it is not correct, follow the instructions on page 100
for changing the ST-133A Controller's voltage setting
and fuses.
