TABLE 2-2 3-PHASE INPUT POWER REQUIREMENTS
WARNING! An overcurrent protection device
(i.e., circuit breaker) is required in the building
installation. The circuit breaker should be rated for
continuous current as required by the SW system (see
Table 2-2). Installation should comply with local safety
standards.
A device to disconnect the SW 10500, SW 15750, or
SW 21000
from the energy supply source is also
required. This switch or circuit breaker must be close
to the SW system, within easy reach of the operator,
and clearly labeled as the disconnection device for the
SW system.
2.5.1 OPTIONAL SW INPUT FILTER WIRING
Prior to mounting the optional input power line filter (required for CE), pre-wire the input
power to the filter (line side) and pre-wire the filter (load side) to the SW 5250M (master)
and SW 5250S (slave[s]). Input power cable assemblies 5161398-01 are provided to
interface from the filter (load side) to the SW 5250M and SW 5250S chassis inputs. Refer
to Figures 2-8 through 2-16.
Insert the cable assembly end labeled FILTER LOAD SIDE into the filter rear panel cutout,
then secure the cable clamp with the nut. Connect the ring lugs to the filter load side as
indicated by the filter and wire labels. Connect the chassis ground wire to the internal
chassis ground stud. Insert the cable assembly end labeled SW 5250 INPUT into the
master and slave(s) rear panel cutouts, then secure the cable clamp with the nut. Connect
the cable assembly to the SW 5250 input as indicated by the rear panel and wire labels.
Connect the chassis ground wire with ring lug to the chassis ground stud.
An overall shield is provided on each cable from the filter to the SW master or slave(s).
Cable clamps are used to connect this shield at both ends to the chassis.
