Planning the Kinetix 2000 Drive System Installation 21
Circuit Breaker/Fuse Selection
The Kinetix 2000 system utilizes internal short circuit output protection and is
suitable for use on a circuit capable of delivering up to 100,000 Amperes, when
protected by class CC, J, L, and R fuses. Circuit breakers with adequate
widthstand and interrupt ratings, as defined in NEC 2002, article 110.9 and
110.10, are also permitted.
The Bulletin 140M product may be another acceptable means of protection
with the Kinetix 2000 system. As with fuses and circuit breakers, you must
make sure that the selected components are properly coordinated and meet
applicable codes. When applying the 140M product, evaluation of the short
circuit available current is critical and must be kept below the short circuit
rating of the 140M product. As long as you do this review, and the conditions
for use are met, the 140M product is appropriate for use with the Kinetix 2000
system.
The line interface module (LIM) contains different circuit protection based on
type:
• 2094-AL09 contains supplementary protection device, 1492-CB (UL
508), and therefore class CC or J fuses with 5kA SCCR must be used on
the line side of the 2094-AL09 LIM.
• 2094-AL15S, 2094-AL25S, 2094-AL50S, 2094-AL75S, and 2094-XL75S
contain Bulletin 140U (UL 489) motor branch circuit protection.
Overcurrent protection must be adequately coordinated per NEC 2002, article
240.
In most cases, fuses selected to match the drive input current rating will meet
the NEC requirements and provide the full drive capabilities. Dual element,
time delay (slow acting) fuses should be used to avoid nuisance trips during the
inrush current of power initialization.
Refer to Circuit Breaker/Fuse Specifications on page 157 for recommended
circuit breakers and fuses.
Refer to Power Specifications on page 154 for input current and inrush current
specifications for your IAM.
Enclosure Selection
The following example is provided to assist you in sizing an enclosure for your
Kinetix 2000 system. The example system consists of the following
components:
• Six-axis Kinetix 2000 servo drive system
• Line Interface Module (LIM)
• ControlLogix chassis and modules (controller)
Size the Kinetix 2000 servo drive and LIM and use the results to predict the
amount of heat dissipated into the enclosure. You will also need heat
