Vector And Topper Group Operated Air Break Switches
DANGER
Hazardous voltages and high speed moving parts.
Will cause death, serious injury or property damage.
Always de-energize and ground the equipment before maintenance.
Read and understand this instruction manual before using equipment.
Maintenance should be performed only by qualified personnel. The use of
unauthorized parts in the repair of the equipment or tampering by unqualified
personnel will result in dangerous conditions that will cause death, severe
injury or equipment damage. Follow all safety instructions contained herein.
Important
The information contained herein is general in nature and not intended for
specific application purposes. It does not relieve the user of responsibility
to use sound practices in application, installation, operation, and
maintenance of the equipment purchased. Siemens reserves the right to make
changes in the specifications shown herein or to make improvements at any time
without notice or obligation. Should a conflict arise between the general
information contained in this publication and the contents of drawings or
supplementary material or both, the latter shall take precedence.
Qualified person
For the purpose of this instruction manual a qualified person is one who has
demonstrated skills and knowledge related to the installation, construction,
and operation of the equipment and the hazards involved. In addition, this
person has the following qualifications:
-
Is trained and authorized to de-energize, clear, ground and tag circuits and equipment in accordance with established safety procedures.
-
Is trained in the proper care and use of protective equipment, such as: rubber gloves, hard hat, safety glasses or face shields, flash clothing, etc. in accordance with established safety practices.
-
Is trained in rendering first aid.
Further, a qualified person shall also be familiar with the proper use of special precautionary techniques, personal protective equipment, insulation and shielding materials, and insulated tools and test equipment. Such persons are permitted to work within limited approach of exposed live parts operative at 50 volts or more, and shall, at a minimum, be additionally trained in all of the following: -
The skills and techniques necessary to distinguish exposed energized parts from other parts of electric equipment.
-
The skills and techniques necessary to determine the nominal voltage of exposed live parts.
-
The approach distances specified in NFPA 70E® and the corresponding voltages to which the qualified person will be exposed.
-
The decision-making process necessary to determine the degree and extent of the hazard and the personal protective equipment and job planning necessary to perform the task safely.
Signal words
The signal words “danger,” “warning,” and “caution” used in this instruction
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 injury.
Caution ‒ Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.
Notice (without safety alert symbol) ‒ Indicates a potentially hazardous
situation which, if not avoided, may result in property damage.
Field service operation and warranty issues
Siemens can provide competent, well trained field service representatives to
provide technical guidance and advisory assistance for the installation,
overhaul, repair and maintenance of Siemens equipment, processes and systems.
Contact regional service centers, sales offices or the factory for details, or
telephone Siemens field service at +1
800-347-6659 or +1
423-262-5700 outside the U.S.
For medium voltage customer service issues, contact Siemens at +1
800-347-6659 or +1
423-262-5700 outside the U.S.
NOTE: These instructions do not purport to cover all details or
variations in equipment, nor to provide for every possible contingency to be
met in connection with installation, operation or maintenance. Should further
information be desired or should particular problems arise that are not
covered sufficiently for the purchaser’s purposes, the matter should be
referred to the local sales office.
The contents of this instruction manual shall not become part of or modify any
prior or existing agreement, commitment or relationship. The sales contract
contains the entire obligation of Siemens Industry, Inc. The warranty
contained in the contract between the parties is the sole warranty of Siemens
Industry, Inc. Any statements contained herein do not create new warranties or
modify the existing warranty.
NOTE: If the switch is not kept in good working order by proper
inspection and care, the service life of the switch may be affected and the
probability of a failure during operation increases. Frequency of inspections
will be a function of atmospheric contamination, frequency of operation, fault
current exposure, etc. The user must establish and follow a suitable
maintenance program. The following are some suggested items to check, but
should not be considered an all inclusive listing:
-
Periodically operate the switch several times and check for proper operation as described in installation / check-out instructions. Clean and re-lubricate the jaw contacts and the end of the blade with factory approved grease.
NOTE: NEVER use a non-oxide grease, or the type of inhibitor based electrical joint compound designed for solid bolted connections, on either the hinge or jaw contacts. If used, the inhibitor will lock-up these moving contacts. -
When the switch is being operated, if the blade requires light effort to rotate after it is clear of the interrupter lever or jaw contacts, lubricate the hinge with a penetration spray type lubricant such as N.W. Anti-Corrosion A-120 or better.
NOTE: Silicone lubricants, heavy oils or greases are not recommended. -
If equipped with an interrupter, remove the Saf-T-Gap interrupter and check the mechanical action by hand. If the interrupter is stiff:
a. Clean the push rod with xylol and re-lubricate the push rod with factory approved oil and operate several times by hand.
b. If the interrupter is still stiff or the push rod has a very heavy coating of corrosion, it is probably time to replace the interrupter.
NOTE: The internal mechanism of the interrupter does not require maintenance.
Any attempt to do so may damage the interrupter. -
Check for insulators that are cracked, broken, flashed over, etc.
-
Check for any visual shipping damage to the hot parts, including the interrupter.
-
Check hardware, especially terminal pad bolts (including pole hardware.)
-
Visually inspect terminal pad area for corrosion and/or overheating.
NOTE: A thermal vision test of the entire switch installation, if equipment is available, would be preferred in lieu of a visual inspection. -
Refer to ANSI C37.35 for additional recommendations. C37.35 is “IEEE guide for the Application, Installation, Operation and Maintenance of High-Voltage Air Disconnecting and Load Interrupter Switches.”
Disposal
Siemens equipment is environmentally friendly product predominantly consisting
of recyclable materials. For disposal, some disassembly, separation, and
professional services handling may be required.
Materials to be handled include but are not limited to:
- Metals: Should be transferred and recycled as mixed scrap metals.
- Plastics: Plastic containing a recycle symbol should be recycled. Plastic lacking the recycle symbol should be discarded as industrial waste.
- Small electronics, insulated cables, and motors: Should be recycled via electronics scrap disposal companies specialized in separating and sorting as described above.
- Batteries: Should be recycled via a recycling company.
Disposal regulations vary from locality to locality and may be modified over time. Specific regulations and guidelines should be verified at the time of waste processing to ensure that current requirements are being fulfilled. For specific assistance in understanding and applying regional regulations and policies or manufacturer’s recommendations, refer to the local Siemens service representative for additional information.
| WARNING
Stored energy.
Can cause death, serious injury, or property damage.
Mechanisms contain stored energy, which may be released during disassembly.
Wear suitable protection and take appropriate precautions when disconnecting
and removing moving parts.

| WARNING
Heavy objects.
Can cause death or serious injury.
Disassembly may cause an unbalanced load, and could result in falling objects.
Take appropriate precautions in a properly designated workspace to maxmize
support and stability.
