Lifting and moving
There are a number of methods that can be
used in handling the type SDV7 distribution
circuit breaker that, when properly
employed, will not damage the type SDV7
distribution circuit breaker. The handling
method used will be determined by
conditions and available equipment at the
installation site. Lifting with a crane by the
use of a sling and lifting lugs is the preferred
method of handling; however, overhead
obstructions often dictate that other
methods must be used. Forklift trucks may
be used prior to removal of wooden skids.
Verify the forklift blades pass completely
through the wooden skid under the circuit
breaker.
Each type SDV7 distribution circuit breaker
has provisions for attaching lifting cables.
Lifting lugs are provided on two sides of the
circuit breaker, which are designed for use
with a lift sling or hooks of the proper size
and a crane of adequate height and
capacity. Refer to the type SDV7 distribution
circuit breaker nameplate for the weight.

Recommended lifting of type SDV7
distribution circuit breakers is by means of
cables connected to an overhead crane. The
cables are connected to the lifting lugs on
the top of the type SDV7 distribution circuit
breaker as illustrated in Figure 2: Lifting
type SDV7 distribution circuit breaker with
crane. A crane with sufficient height should
be used so the load angle on the lifting
cable will be approximately 60° when
viewed from the front or rear.
Storage
When it is necessary to store a type SDV7
distribution circuit breaker in an area
exposed to the weather or under humid
conditions, energize the space heaters
provided and make certain that any vents
are uncovered to allow air to circulate. If at
all possible, install the type SDV7
distribution circuit breaker at the permanent
location even though it may be some time
before the equipment is used. It is also
recommended that the type SDV7
distribution circuit breaker receive periodic
inspection during storage.
Access to the heater circuit is gained by
opening the door to the relay and control
compartment. Refer to the wiring diagram
drawing for space heater circuit
connections. Lubricate hinges and other
moving parts.
Heavy weight.
Can result in death, serious injury or property damage.
Observe all handling instructions in this instruction manual to prevent
tipping or dropping of equipment.
