3.2 Source Branch Circuit Protection
Branch circuit protection must be installed in the circuit sourcing the drive. See Table 3 for
recommended circuit breaker/fuse sizing, which is based on 125% of the rated input current. Fuses may
be used for circuit protection; consult local electrical code for proper sizing. Installation of a disconnect
means within sight of the drive is recommended.

3.3 Installing Power Cables
CAUTION: Installations must comply with all NEC and local electrical code requirements.
Connection to input and output power is made on the power terminal block. See Table 4 for connection
descriptions and Figure 14 for terminal block locations.
Important Note About Output Filters:
Models that include a sinewave filter have a different power terminal connection configuration. Refer to
Figure 15 for connecting models with output filters.
