CAUTION
Before attempting to apply input power to the IMUX 2000, you must make sure
that its power supply module(s) will operate at the available input supply voltage.
If an incorrect power supply module is installed, component damage may result.
8.2.4 POWER SUPPLY INPUT VOLTAGE CHECK
Before re-inserting the power supplies into the IMUX 2000, check the model number stamped on the
supply to make sure the supply is compatible with the available input power. Four different power
supply modules are used in the IMUX 2000:
Model Designation Part Number Input Voltage
2000 PS 250DC 9547-840 250 Vdc
2000 PS 120AC 9547-850 120 Vac
2000 PS 24DC 9547-910 24 Vdc
2000 PS 48/125DC 9547-920 48/125 Vdc
2000 PS 220AC 9547-930 220 Vac
NOTE
There is a label on the inside front door of the IMUX 2000. (See Figure 8-4.) This label is
marked to indicate which model power supply(s) was installed before it left the factory. If
you change the power supply module(s) with a different model, you must change the
markings on this label to reflect the change.
A CAUTION label is also located on the inside of the front cover of the IMUX 2000 which
alerts the user to keep hands away from the power supply module. (See Figure 8-5.)
