Rockwell Automation 1336R REGEN LINE REG - Manual (Page 20)

2–4 Regenerative DC Bus Supply Operation
Input Fusing
Customer Supplied Fusing
Based on the maximum 1336 REGEN Package voltage rating, the
following customer supplied fuses are recommended.
1336 REGEN Precharge Fusing
The 1336 REGEN Precharge Circuit Board is internally fused to
protect precharge components. When replacing 1336 REGEN
Precharge Unit fuses F1, F2
& F3 (shown in Figure 2.12), use only
the type and size specified below.
!
ATTENTION: 1336 REGEN equipment does not
provide input power short circuit fusing. Branch circuit
breakers or disconnect switches cannot provide this
level of protection for converter and precharge unit
components. Specifications for the recommended fuse
size and type to provide input power protection against
short circuits at the Converter or Precharge Unit is listed
below.
!
ATTENTION: To guard against personal injury and/or
equipment damage caused by improper fusing, use only
the recommended line fuses specified.
