HX7+ ASD Installation and Operation Manual 25
Power Connection Requirements
Connect the 3-phase input power of the correct voltage to the input terminals of the ASD at R/L1, S/L2,
and T/L3 (see
Figure 5 for the typical electrical connection scheme and Figure 6 on pg. 26 for the
terminal locations).
Connect the output of the ASD to the motor from the ASD terminals U/T1, V/T2, and W/T3. The input
and output conductors and terminal lugs used shall be in accordance with the requirements listed in the
section titled
Voltage/Current and Thermal Specifications on pg. 230.
Install a molded case circuit breaker (MCCB) or fuse between the 3-phase power source and the ASD in
accordance with the fault current setting of the ASD and the NEC Article 430.
The ASD is designed and tested to comply with UL Standard 508C. Modifications to the ASD system
may disqualify the UL rating.
As a minimum, the installation of the ASD shall conform to the NEC Article 110, the Occupational
Safety and Health Administration requirements, and to any other local and regional industry codes
and standards.
Note: In the event that the motor rotates in the wrong direction when powered up, reverse
any two of the three ASD output power leads (U, V, or W) connected to the motor.
