Section 2: receiving, Handling and
installation
2-1 General Information
Types DSII and DSLII Circuit Breakers, when supplied as part
of a metal-enclosed switchgear assembly, may be shipped
completely assembled and already installed in their respec-
tive breaker compartments. Receiving and handling of this
equipment is addressed in an assembly instruction manual
supplied with the assembled equipment. This instruction
manual still applies, however, to all other aspects of the
circuit breakers.
Before beginning to unpack new DSII breakers, read and
understand these directions. Following the directions will
ensure that you have caused no damage.
Every effort is made to insure that DSII breakers arrive at
their destination undamaged and ready for installation. Care
should be exercised, however, to protect the breakers from
impact at all times. Do not remove protective packaging until
the breakers are ready for inspection, testing and/or instal-
lation. Shipping containers should be inspected for obvious
signs of rough handling and/or external damage incurred dur-
ing the transportation phase. Record any observed damage
for reporting to the transportation carrier and Eaton, once
the inspection is completed. All reports and claims should be
as specific as possible and include shop order and general
order information.
2-2 Unpacking Circuit Breaker
When ready to inspect and install the DSII breaker, care-
fully open the shipping container and remove any packing
material and any internally packed documentation. The circuit
breaker is designed and balanced to be easily lifted from the
shipping container using the appropriate lifting yoke and an
overhead or portable lifting device.
CAUTION
DO NOT ATTEMPT TO LIFT BREAkERS WITH ORDINARY
CRANE HOOkS, ROPES, CHAINS OR OTHER SUCH DEVICES. FAIL-
URE TO FOLLOW THIS CAUTION COULD RESULT IN DAMAGE TO
VITAL PARTS SUCH AS ARC CHUTES, BARRIERS AND WIRING.
2-2.1 Storing Circuit Breaker
If it is necessary to store a circuit breaker before installa-
tion, do so in its original shipping container. Keep the circuit
breaker in a clean dry place. Ensure there is ample air circu-
lation and heat, if necessary, to prevent condensation. It is
very important that the insulation used in the breaker not be
exposed to dirt or moisture.
NOTICE
A CIRCUIT BREAkER THAT HAS BEEN STORED FOR ANY LENGTH
OF TIME SHOULD BE OPERATED A MINIMUM OF FIVE TIMES
BEFORE IT IS PLACED IN SERVICE.
2-3 Lifting Circuit Breaker
To closely examine, install or just to become more familiar
with the circuit breaker, carefully lift and place the breaker on
a solid work surface capable of handling the breaker’s weight
(Table 2.1) or on the captive drawout extension rails of the
breaker compartment (Figure 1-4). This is accomplished by
using the appropriate lifting yoke and lifter. The lifting yoke
consists of two sheet steel hooks specially shaped to hook
under the top edges of the large openings on each circuit
breaker side sheet (Figure 2-1).
