Incoming Power Connections; Grounding - GE CR194 Installation Instructions Manual

Step 3.
If the contactor is a stationary type, install and torque
the three l oad side connection bolts to 1 6ft-lb. (See
Figure 1 8 ) , then attach the l ine cables to the bottom
of the fuse assembly and torque these con nections to
9 ft-lb. (See Figure 20).
WARNING: Be absolutely certain that these bolts
are properly installed and torqued. These are cur­
rent carrying connections and must be tight or
damage wil l result.
Step 4.
If the contactor is a drawout type, reinstall the two
positioning bolts (See Figure 19) .
Step 5.
Manually operate the con tactor armature and observe
that the mechanical interlock functions properly.
Step 6.
Reconnect the con trol umbilical cord to the contactor
and be sure the retaining wing nuts are tight. Installa­
tion of the con tactor is now complete.
WARNING: Make certain that all barriers are re­
placed and bolted tightly into position. Make sure
the line and load side terminations of the station­
ary contactor are torqued properly. If the contactor
is drawout type, make sure the positioning bolts
are installed properly. Failure to perform these op­
erations could result in failure of the unit to oper­
ate safely and reliably.

Incoming Power Connections

The compact design of the two-high vacuum
Limitamp® does not make it practical to terminate in­
coming power cables within the starter. The equip­
ment must either be bus spliced to existing equipment
or supplied with a separate cable entrance compart­
ment. If a separate cable entrance compartment is sup­
plied, refer to the Outline Summary & Outline Details
sections of th e drawings provided with the equipmen t
to determine th e recommended location for incoming
power cable en try. Also see the "Cable Termination
Guidelines" section of this instruction .

Grounding

All con troller enclosures must be grounded, and th e
CR194 two-high vacuum Limitamp® is equipped with a
ground bus for that purpose. The two-high ground bus
should be bus connected to existing equipment or to a
separate cable entrance compartment. Figure 28 shows
the ground bus as seen from the rear of the enclosure
with the back cover removed.
In order to accommodate motor cable grounds, each
starter cubicle is equipped with a ground bus link that
is connected di rectly to the horizontal ground bus.
See Figure 29 .
