LONG USEFUL LIFE OF THE UNITS. IT IS FURTHER RECOMMENDED THAT
THE INSTALLATION BE PERFORMED BY A EATON CORPORATION TRAINED
ENGINEER OR TECHNICIAN.
VSR-SERIES UNITS ARE PROTECTIVE DEVICES, AS SUCH, THEY ARE
MAXIMUM RATED DEVICES. THEREFORE, THEY SHOULD NOT UNDER ANY
CIRCUMSTANCE BE APPLIED OUTSIDE THEIR NAMEPLATE RATINGS.
WARNING
This book is intended to be used in conjunction with the technical
information provided with the original equipment order which
includes, but is not limited to electrical control schematics and wiring
diagrams, outline diagrams, installation plans, and procedures for
installation and maintenance of accessory items.
Satisfactory performance is dependant upon proper application,
correct installation, and adequate maintenance. It is strongly
recommended that this instruction book be carefully read and
ALL POSSIBLE CONTINGENCIES WHICH MIGHT ARISE DURING
INSTALLATION, OPERATION, OR MAINTENANCE, AND ALL DETAILS
AND VARIATIONS OF THIS EQUIPMENT ARE NOT COVERED BY THESE
INSTRUCTIONS. IF FURTHER INFORMATION IS DESIRED BY THE
PURCHASER REGARDING A PARTICULAR INSTALLATION, OPERATION, OR

SECTION 2: SAFE PRACTICES
VSR-Series units are equipped with high speed, high energy
operating mechanisms. They are designed with several built-in
interlocks and safety features to provide safe and proper operating
sequences.
WARNING
TO PROTECT THE PERSONNEL ASSOCIATED WITH INSTALLATION,
OPERATION, AND MAINTENANCE OF THESE UNITS, THE FOLLOWING
PRACTICES MUST BE FOLLOWED:
•
Only qualified persons, as defined in the National Electrical
Safety Code, who are familiar with the installation and
maintenance of medium voltage circuits and equipment,
should be permitted to work on these units.
•
Read these instructions carefully before attempting any
installation, operation or maintenance of these units.
•
Always remove the unit from the enclosure before
performing any maintenance. Failure to do so could result in
electrical shock leading to death, severe personnel injury or
property damage.
•
Do not work on a unit with the secondary test coupler
engaged. Failure to disconnect the test coupler could result
in an electrical shock leading to death, personnel injury or
property damage.
•
Do not work on a closed unit. The main contacts should be
open before working on the unit. Failure to do so could result
in cutting or crushing injuries.
•
Do not use a MV-VSR by itself as the sole means of isolating
a high voltage circuit. Remove the unit to the Disconnect
position and follow all lockout and tagging rules of the
National Electrical Code and any and all applicable codes,
regulations and work rules.
•
Do not leave the unit in an intermediate position in the
cell. Always have the unit either in the Test or Connected
position. Failure to do so could result in a flash over and
possible death, personnel injury or property damage.
•
These units are equipped with safety interlocks. Do not
defeat them. This may result in death, bodily injury or
equipment damage.

SECTION 3: RECEIVING, HANDLING, AND
STORAGE
Type VCP-W VSR-series breaker to vacuum starter replacement units
are subjected to complete factory production tests and inspection
before being packed. They are shipped in packages designed to
provide maximum protection to the equipment during shipment
and storage and at the same time to provide convenient handling.
Accessories such as the cell code plate, etc. are shipped with the
unit (Figure 3.1).
3.1 RECEIVING
Until the unit is ready to be delivered to the switchgear site for
installation, DO NOT remove it from the shipping crate. If the unit
is to be placed in storage, maximum protection can be obtained by
keeping it in its crate.
Upon receipt of the equipment, inspect the crates for any signs of
damage or rough handling. Open the crates carefully to avoid any
damage to the contents. Use a nail puller rather than a crow bar
when required.
When opening the crates, be careful that any loose items or
hardware are not discarded with the packing material. Check the
contents of each package against the packing list.
Examine the unit for any signs of shipping damage such as broken,
missing or loose hardware, damaged or deformed insulation and
other components. File claims immediately with the carrier if
damaged or loss is detected and notify the nearest Eaton’s Electrical
Services & Systems office.
3.2 HANDLING
WARNING
DO NOT USE ANY LIFTING DEVICE AS A PLATFORM FOR PERFORMING
MAINTENANCE, REPAIR OR ADJUSTMENT OF THE UNIT OR FOR OPENING,
CLOSING THE CONTACTS OR CHARGING THE SPRINGS. THE UNIT MAY
SLIP OR FALL CAUSING SEVERE PERSONAL INJURY. ALWAYS PERFORM
MAINTENANCE, REPAIR AND ADJUSTMENTS ON A WORKBENCH
CAPABLE OF SUPPORTING THE UNIT.
VCPW-VSR unit shipping containers are designed to be handled
either by use of a rope sling and overhead lifting device or by a
fork lift truck. If containers must be skidded for any distance, it is
preferable to use roller conveyors or individual pipe rollers.
Once the unit has been inspected for shipping damage, it is best to
return it to its original shipping crate until it is ready to be installed in
the Metal-Clad Switchgear.
When the unit is ready for installation, a lifting harness in conjunction
with an overhead lift or portable floor lift can be used to move the
unit, if this is preferable to rolling the unit on the floor using self
contained wheels. If the unit is to be lifted, position the lifting device
(lifting straps should have at least a 1600 pound capacity) over the
unit and insert the lifting harness hooks into the unit side openings
and secure. Be sure the hooks are firmly attached before lifting
the unit. Stand a safe distance away from the unit while lifting and
moving.
Tools and Accessories
Contact Wear Gauge: Optional item used to check contact wear.
(Style 5259C11H01) (See Section 5)
Racking Handle: The original VCP-W racking handle is used to assist
in moving the MV-VSR into and out of the cell.
Lifting Yoke: Optional lifting device that can be used to install a VSR
into upper compartment of VCP-W switchgear. (Style 94M7103G99)

3.3 STORAGE
If the MV-VSR is to be placed in storage, maximum protection
can be obtained by keeping it in the original shipping crate. Before
placing it in storage, checks should be made to make sure that the
unit is free from shipping damage and is in satisfactory operating
condition.
The unit is shipped with its contacts open, the indicators on
the front panel should confirm this. Outdoor storage is NOT
recommended. If unavoidable, the outdoor location must be well
drained and a temporary shelter from sun, rain, snow, corrosive
fumes, dust, dirt, falling objects, excessive moisture, etc. must be
provided. Containers should be arranged to permit free circulation of
air on all sides and temporary heaters should be used to minimize
condensation. Moisture can cause rusting of metal parts and
deterioration of high voltage insulation. A heat level of approximately
400 watts for each 100 cubic feet of volume is recommended with
the heaters distributed uniformly throughout the structure near the
floor.
3.4 VCPW-VSR APPROXIMATE WEIGHTS

Indoor storage should be in a building with sufficient heat and
circulation to prevent condensation. If the building is not heated, the
same general rule for heat as for outdoor storage should be applied.
