The Rear Panel
An illustration of the rear panel of the Model 5300 console is shown below:
Setting Power Line Voltage
Although the Model 5300 system is configured by ADE Technologies before shipment, you should verify
that the power entry module is set for the correct line voltage before turning the unit on. Locate the power
entry module on the Model 5300 rear panel and note what voltage designation the white pin is near. If the
voltage is not set correctly for your facility's input power, you may easily change the setting. First, remove
the power entry module cover (by prying it off with a small screwdriver). Rotate the small circuit card inside
to the correct position for the available power line voltage and replace the cover.
Note that the 5300 can be set to accept four international voltages:
n
100 VAC, 50 to 60 Hz
n
120 VAC, 50 to 60 Hz
n
220 VAC, 50 to 60 Hz
n
240 VAC, 50 to 60 Hz
The Model 5300 has a built-in safety mechanism to protect the electronics against improper line voltages.
For example, if the power entry module was set for 100 or 120 VAC and plugged into 220 or 240 VAC, a
crowbar circuit would instantaneously cause the fuses to blow, thereby protecting the electronics. Constant
fuse outage, therefore, is normally a sign of an improperly-set power entry module.
