protection.
UL listed Class J time-delay fuses are provided with your panel. These fuses
have been sized in accordance to NEC section 450-52 and Table 450-152.
NEC states fuses of this type are to be sized at 175% of motor full-load amps
(FLA). Due to the fact that actual motor FLA along with starting current
requirements vary between manufacturer and motor types the fuses
provided are based on standard NEC motor data. Verify that the input fuse
amp rating is less than or equal to the actual motor FLA * 1.75. In the case
where the actual motor FLA * 1.75 is less than the provided fuses amp rating
then smaller fuses may need to be installed to be in compliance with NEC
section 430-52 and Table 430-152. Please note exception 1 to NEC 430-52,
which states that where the calculated fuse amp rating does not correspond
to a standard fuse size the next higher standard fuse size may be used. In
cases where the fuses provided is not sufficient for the starting current
requirements of the motor, please note exception 2-b to NEC 430-52.
Exception 2-b states the rating of a time-delay fuse may be increased but
shall not exceed 225% of the motor FLA in any case. In the case where a
larger or smaller fuse is required, a limiting factor in the bypass panel may be
the fuse holder. The appendices provide a table for the maximum fuse size
permitted in the existing fuse holder.
5. AF 600 FP Drive Function Code Changes
The AF 600 FP Adjustable Frequency Drive has programmable function. A complete description of these
function codes can be found in DET – 609 manuals. The purpose of this section is to identify those function
codes, which changed from the factory drive defaults for panel installation.
