Introduction and Safety

Introduction

The SDV (generic family name for SDV-4A) vacuum break-
ers are designed to meet all applicable ANSI, NEMA, and
IEEE standards. Successful application and operation of
this equipment depends as much upon proper installation
and maintenance by the user as it does upon the careful
design and fabrication by Siemens.
The purpose of this instruction manual is to assist the user
in developing safe and efficient procedures for the instal-
lation, maintenance and use of the equipment.
Contact the nearest Siemens representative if any additional
information is desired.
Hazardous voltages and high-speed moving
parts.
Will cause death, serious injury or property
damage.
To avoid electrical shock, burns and entangle-
ment in moving parts this equipment must be
installed, operated and maintained only by
qualified persons thoroughly familiar with the
equipment, instruction manuals and drawings.
Read and understand this instruction manual
before using equipment.

Qualified Person

For the purpose of this manual a Qualified Person is one
who is familiar with the installation, construction or opera-
tion of the equipment and the hazards involved. In addi-
tion, this person has the following qualifications:
• Training and authorization to energize, de-energize, clear,
ground and tag circuits and equipment in accordance
with established safety practices.
• Training in the proper care and use of protective
equipment such as rubber gloves, hard hat, safety
glasses, face shields, flash clothing, etc., in accordance
with established safety procedures.
• Training in rendering first aid.

Signal Words

The signal words "Danger", "Warning" and "Caution" used
in this manual indicate the degree of hazard that may be
encountered by the user. These words are defined as:
Danger - Indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
Warning - Indicates a potentially hazardous situation
which, if not avoided, could result in death or serious in-
jury.
Caution - indicates a potentially hazardous situation which,
if not avoided, may result in minor or moderate injury.
Caution (without safety alert symbol) - indicates a poten-
tially hazardous situation which, if not avoided, may re-
sult in property damage.

Hazardous Procedures

In addition to other procedures described in this manual
as dangerous, user personnel must adhere to the follow-
ing:
1. Always work only on a de-energized breaker. The breaker
should be isolated, grounded, and have all control power
removed before performing any tests, maintenance or
repair.
2. Always perform maintenance on the breaker after the
spring-charged mechanisms are discharged (except for
test of the charging mechanisms). Check to be certain
that the indicator flags read OPEN and DISCHARGED.
3. Always let an interlock device or safety mechanism per-
form its function without forcing or defeating the de-
vice.
