Electrical Requirements
Use the following tables to plan your site power requirements. The tables list the
voltage inputs, grounding, plugs, and receptacles necessary for your new printer.
All voltages are single-phase.

Power Cord
Place the printer so the power cord can plug into the power receptacle without
putting stress on the power cord. The standard power cord length in the U.S. and
in all other countries is 2.74 m (9 ft). A 1.83 m (6 ft) power cord is also available in
the U.S.
Safety
Safety is a major consideration in the design and manufacture of IBM products.
Proper electrical grounding is essential for safety and for reliable operation of the
printer. If you have any questions about the grounding of your receptacle, ask your
electrician.
Branch Circuits and Grounding
A machine must be properly grounded. It is recommended that an insulated
green-wire ground, the same size as the phase wire, be installed between the
branch circuit panel and the receptacle.
For personal safety, the ground should have sufficiently low impedance to limit the
voltage to ground and to facilitate the operation of circuit protective devices in the
circuit. For example, the ground path must not exceed 1 ohm for 120-volt,
20-ampere branch circuit devices.
CAUTION:
The construction of this machine provides extra protection against the risk of
electric shock by grounding appropriate metal parts. The extra protection
may not function unless the power cord is connected to a properly grounded
outlet. This machine has a grounding-type (3-wire) power cord because
grounding is necessary. It is the responsibility of the customer or the person
installing the machine to connect it to a properly grounded outlet. Seek
professional assistance before using an adapter or extension cord; such a
device could interrupt the grounding circuit.
