| Types SDV-R and SDV-R-AR distribution circuit breakers
Functional tests
Refer to the installation checklist in the
installation checks and initial functional tests
section of this instruction manual. Functional
tests consist of performing at least three
manual spring-charging checks and three
automatic spring-charging checks. After these
tests are complete, and the springs fully
discharged, all fasteners and connections are
checked again for tightness and condition.
Risk of insulation damage with use of
incorrect compounds.
May cause equipment dielectric failure.
Use only isopropyl alcohol to clean insulation. Do
not use any cleaning compounds containing
chlorinated hydrocarbons such as
trichlorethylene, perchlorethylene or carbon
tetrachloride. These compounds will damage the
material used in the barriers and other insulation
on the circuit breaker.
Protective relays and instruments
The type SDV-R distribution circuit breaker
can be equipped with a protective relay
package supplied on a hinged panel mounted
in the front of the relay and control
compartment.
To ensure satisfactory operation of protective
relays and instruments do not leave device
covers off longer than necessary. When a
cover has been broken, cover the device
temporarily and replace broken cover as soon
as possible.
Refer to the wiring and schematic diagrams,
and other instruction literature shipped with
the circuit breaker for additional specific
protective relay requirements.
Equipment surfaces
Inspect the painted surfaces and touch up
scratches as necessary. ANSI-61 touch-up
paint is available from Siemens. This paint
matches the unit and is thinned and ready for
use in one pint (473 ml) spray cans.
Inspect interior of unit for entrance of
moisture and repair as necessary.
Inspect ventilation filters, clean or replace as
appropriate.
