Grounding and Static Electricity
WARNING!!
It is very important that the power cord is plugged into a properly wired electri-
cal outlet. Failure to have a properly wired outlet may result in damage to the equipment and
personal injury. It is recommended that a licensed electrician be consulted to ensure that the
electrical outlet is properly wired and grounded. If a properly wired electrical outlet is not used
for the source supply voltage to the system, electrical failures may result.
Static Electricity:
As with all computerized equipment, your machine is sensitive to static electricity. Any time work is
performed inside covered areas of the embroidery machine, the person performing the work must use
a static grounding strap or take adequate steps to dissipate static build-up prior to touching electronic
components.
WARNING!!
Failure to use a grounding strap, or failure to practice other good maintenance/
repair techniques may cause damage to the machine and possible personal injury.
CAUTION!!
Unless otherwise specified within these procedures, DO NOT disconnect the
electrical supply input cord from the machine or the electrical input source outlet. Doing so will
remove the ground connection needed to dissipate the electrical static build-up prior to work-
ing on the internal components in the machine. Always make contact with the exterior metal
portion of the machine for about one minute to dissipate any electrical static build-up in your
body before touching any electronic component of the machine, especially the main board.
Grounding Strap Use:
A grounding strap should be connected properly to ensure that static charge on the person’s body is neu-
tralized to the chassis ground of the embroidery machine when working in the electronic areas under the
covers. Proper connection is provided at any bare (unpainted) metal surface or any other surface (such as
a ground screw head) that is known to be an earth ground. If a ground strap is not used or is not avail-
able, touch the chassis for about a minute to dissipate any static build-up before you touch any electronic
component inside the machine (with the machine turned off and the power input cord connected to an
electrical outlet).
WARNING!!
DO NOT attempt to use any grounding strap that is not specifically designed for
static use. A “straight-wire” grounding device (one without built-in resistance) will place the
operator in danger of exposure to dangerous voltages. It is recommended that the static strap
be checked during daily use for proper resistance protection.
