BSPD SPDs for switchgear and power distribution panels Instruction Sheet IS10207 Rev 3
Effective July 2015
HAZARD OF ELECTRIC SHOCK,
EXPLOSION OR ARC FLASH
WILL RESULT IN DEATH OR SERIOUS
INJURY
Working on or near energized circuits poses
a serious risk of electric shock. De-energize
all circuits before installing or servicing this
equipment and follow all prescribed safety
procedures.
ELECTRIC SHOCK HAZARD
Ungrounded power systems are inherently
unstable and can produce excessively high
line-to-ground voltages during certain fault
conditions.
During these fault conditions any electrical
equipment, including an SPD, may be
subjected to voltages, which exceed their
designed ratings.
This information is being provided to the
user so that an informed decision can
be made before installing any electrical
equipment on an ungrounded power
system.
1.5 Signal words
The signal words “DANGER,” “ WARNING,” “ CAUTION” and
“NOTICE” (along with their assigned symbol) throughout this
manual indicate the degree of hazard the user may encounter.
These symbols and words are defined as:
DANGER: Indicates a hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING: Indicates a hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTION: Indicates a hazardous
situation which, if not avoided, could
result in minor or moderate injury.
NOTICE: Indicates a hazardous
situation which, if not avoided, could
result in property damage.
1.6 Qualified person
For the purpose of this Instruction Leaflet, a qualified person:
(a) is familiar with the subject equipment and the hazards involved
with their application, use, administration and maintenance.
(b) is trained and authorized to de-energize, clear, ground, and tag
circuits and equipment in accordance with established safety
practices.
(c) is trained in the proper care and use of personal protective
equipment such as rubber gloves, hard hat, safety glasses or face
shields, arc-flash clothing, etc., in accordance with established
safety practices.
(d) is trained to render first aid.
(e) has received safety training to recognize and avoid the hazards
involved.
(f) has the skills and knowledge pertaining to the construction and
operation of this equipment and its installation.
IMPORTANT: These procedures do not claim to cover all possible
details or variations encountered with the installation of a Surge
Protective Device (SPD), nor do they provide for all possible
conditions that may be encountered. If further information is
desired or needed to address any particular issue not covered in
this document, contact your Bussmann products representative.
The information in this document does not relieve the user from
exercising good judgment, nor from using sound safety practices.
Note: Because Eaton has a policy of continuous product
improvement, we reserve the right to change design specifications
without notice. Should a conflict arise between the general
information in this document and the contents of drawings or
supplementary material, or both, the latter shall take precedence.

1.7 Safety Concerns
This instruction sheet is not comprehensive. It is assumed the SPD
installer will follow established safety procedures for working in an
electrical environment. For more information on safety precautions
and procedures, consult the following websites:

1.8 Equipment Testing
Every Bussmann series BSPD unit is tested at the factory for
dielectric breakdown. No further SPD testing is required for
installation.
If you desire to test the electrical distribution system or equipment
by performing dielectric, megger, or hi-potential tests, any installed
SPD must be disconnected from the power distribution system to
prevent damage to the unit.
Follow this procedure to safely disconnect the SPD:
For SPDs connected to a circuit breaker or fuse:
A. 3-wire Delta SPDs: Turn off the circuit breaker or remove the
fuses from the fuse holder to isolate the SPD.
B. Wye SPDs: Turn off the circuit breaker or remove the fuses
from the fuse holder to isolate the SPD and remove the Neutral
connection
