B.1 POWER REQUIREMENTS
The 5444 is available for use with either a SOHz or a 60
Hz power supply. The machine index card states the
power supply to which the machine has been built.
B.1.1 50 Hz Power Supply
The 50 Hz power supply is as follows:
220/235Vac ±10%, single phase.
Peak current (starting): 3.5 amperes.
Average current: 1.0 ampere.
B.1.2 60 Hz Power Supply
The 60 Hz power supply is as follows:
208/230V ac
±
10%, single phase.
Peak current (starting): 3.5 amperes.
Average current: 1.0 ampere.
B.2 COMPONENTS
When the power supply frequency or voltage is changed,
change the components listed in Figure B-1.
