3-4 Receiving and Installation MN715P
AC Line Connections
A power disconnect should be installed between the input power service and
the control for a fail-safe method to disconnect power. The control will remain
in a powered-up condition until all input power is removed from the control
and the internal bus voltage is discharged.
Protective Devices
Recommended fuse sizes are based on the following:
115% of maximum continuous current for time delay.
150% of maximum continuous current for Fast or Very Fast action.
Note: These general size recommendations do not consider harmonic
currents or ambient temperatures greater than 40°C.
Be sure a suitable input power protection device is installed. Use the
recommended circuit breaker or fuses listed in Tables 3-3 and 3-4 (Wire Size
and Protection Devices). Input and output wire size is based on the use of
copper conductor wire rated at 75 °C. The table is specified for NEMA B
motors.
