158 Specifications and Dimensions
Circuit Protection under NEC 1999 110-10 (allowed but no longer preferred)
Use class CC, J, L, or R fuses, with current rating as indicated in the table
below. The following fuse examples and Allen-Bradley circuit breakers are
recommended for use with integrated axis modules (2093-AC05-MPx) when
the Line Interface Module (LIM) is not used.

IMPORTANT
Line interface modules (2094-ALxxS and 2094-XL75S-Cx) provide
branch circuit protection to the IAM.
Line interface module 2094-AL09 contains a supplementary protection
device, 1492-CB (UL 508), and therefore class CC or J fuses with 5kA
SCCR must be used on the line side.
Follow all applicable NEC and local codes.

(1) When using Bulletin 1492 or 140M circuit protection devices, the maximum short circuit current available from the source is limited to 5000 A.
(2)
Fuse selection for control power is appropriate for an eight-axis system with the specified IAM.
ATTENTION
Bulletin 1492 and 140M circuit breakers should not be used on the
output of an ac drive as an isolating disconnect switch or motor
overload device. These devices are designed to operate on sine wave
voltage and the drive’s PWM waveform does not permit proper
operation. As a result, damage will occur to the device.
