If a totally external resistor network is used as shown in
calculated wattage, [W] = 17,000 • C farads, is divided in half to size the
precharge and discharge resistors. Parameter F.015 should be set to the sum of
the wattage for both resistors.

Install the Circuit Breaker/Fuse Circuit Protection

To protect the AC input power for single and parallel unit configurations,
install a circuit breaker with supplemental contact (CB) or fuses in the AC
input power line. Refer to
recommended circuit protection devices.
