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 1.A
. The input fuse ratings listed in Table
1.A 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 400 Drive Packages for Fan
& Pump Applications is UL Class J.
Table 1.A Fuse Recommendations
ATTENTION: Most codes require that upstream branch circuit
protection be provided to protect input power wiring. Install the
fuses recommended in Table 1.A
. Do not exceed the fuse ratings.
Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
