Main Fuses (FU1-FU3)
Input line branch circuit protection fuses must be used to protect the input
power lines. If input fuses are not provided with your drive, recommended fuse
values are shown in
Table 5 . The input fuse ratings listed in Table 5 are applicable
for one drive per branch circuit. No other load may be applied to that fused
circuit.
The recommended fuse type for all PowerFlex Drives for Fan and Pump
Applications is UL Class J, 600V.
Table 5 - Fuse Recommendations
ATTENTION: Most codes require that upstream branch circuit protection be
provided to protect input power wiring. Install the fuses recommended in
Table 5 . Do not exceed the fuse ratings. Failure to observe this precaution could
result in damage to, or destruction of, the equipment.
