Plugging In The Printer - Printronix P7000 Series Maintenance Manual

Plugging In The Printer

Power Cord Requirements
In compliance with international safety standards, a P7000 printer is equipped
with a three-pronged electrical plug on the power cord. When this power cord
is plugged into a correctly wired AC power outlet, the ground conductor
ensures that the printer chassis is at ground (earth) electrical potential.
WARNING
Failure to properly ground the printer can result in electrical shock to
the operator.
Never use adapter plugs that have no grounding prong. Never remove
the grounding prong from the power cable plug. If an extension cord is
required, make sure it is a three-wire cable with a properly grounded
plug.
Interface Cable Requirements
To comply with Electromagnetic Compatibility (EMC) regulatory requirements
all interface cables must be of a minimal quality level, be the correct length,
and be properly installed.
RS-232 port and parallel port cables must meet the following specifications:
•
•
•
•
For reference purposes only, two Centronics parallel port cables that have
been tested and found to comply with these requirements are a Belkin® P/N
F2A046-10 and a Primelogic P/N PLU 2823224. Other electrically equivalent
cables are acceptable.
The cable design must be double shielded with a copper braid over an
aluminum mylar foil and not just a conductive foil spiral wrapped around a
drain wire.
The shield must terminate coaxially (360 degrees) to a metal connector
housing and not be terminated by just a simple wire lead.
Cable length, including connectors, must be three meters or less.
The cable connector anchor screws must be securely seated in the
printer receptor hardware.
