POWER SOURCE
The µProcessor Lab and Flexible Disc Unit are both designed to be operated from a
single-phase power source that has one of its current-carrying conductors (neutral)
at ground (earth) potential. Operating from power sources where both current-
carrying conductors are isolated or above ground potential (such as phase-to-phase
on a multiphase system, or across the legs of a 110-220 volt single-phase, three-wire
system) is not recommended, since only the line conductor has over-current (fuse)
protection within the unit.
The ac power connector is a three-wire polarized plug with the ground (earth) lead
connected directly to the instrument frame to provide electric shock protection. Connect
this plug only to a three-wire outlet which has an earth ground. If the unit is connected
to any other power source, the unit frames must be connected to an earth ground system.
The µProcessor Lab and Flexible Disc Unit are both designed to operate from a 115-230
volt nominal line voltage that has a frequency of 50-60 Hz. The Flexible Disc Unit is
factory wired for 115 volts, 60 Hz operation; however, 230 volts, 50 Hz configuration is
available by special order. Each unit has a separate power cord and requires a separate
outlet for the primary power. The system power requirements are as follows:
8002 µProcessor Lab
Flexible Disc Unit
3.5 amps at 115V,±10%, 60 Hz
2.0 amps at 230 V, ± 10%, 50 Hz
3.0 amps at 115 V, ± 10%, 60 Hz
1.5 amps at 230 V, ± 10%, 50 Hz
NOTE
The Flexible Disc Unit has a warning sign above the primary input power jack
stating the unit is wired for a specific voltage and frequency at the factory.
