CHECK
GENERAL
AFTER INSTALLATION, BUT BEFORE
ENERGIZING THE CONTROLLER for the first
time, follow the procedure below to verify that
the equipment is properly installed and
functional.
Prior to operating the controller, be sure
that the proper withdrawable contactor
carriage is installed in the medium
voltage compartment.
There is a data label (Fig.
on the
side of each contactor carriage
indicating the configuration of that
particular unit. A corresponding label is
located on the inside of each medium
voltage controller compartment door.
Before installing a contactor carriage in
any compartment, verify that the
information on the two labels agrees
completely.
In particular, the following information
must agree:
1.
2.
3.
4.
5.
6.
Part number of contactor
carriage.
Power fuse type, voltage and
current rating
Control voltage and frequency
Contactor type, magnetically
held or latched
Single or dual CPT
Any optional features
Check connections Although the
equipment and devices have been
completely tested at the factory, a final
field check should be made that all
electrical wiring and bus bar
connections are correct and have not
become loose in transportation
(Fig. 40). Refer to MAINTENANCE
Section for electrical joint specification.
