Power Connection Requirements
Connect the 3-phase input power to the input terminals of the ASD at R/L1, S/L2, and T/L3 (see
3 for the typical electrical connection scheme). 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
270.
If multiple conductors are used in parallel for the input or output power and it is necessary to use
separate conduits, each parallel set shall have its own conduit and not share its conduit with other
parallel sets (i.e., place U1, V1, W1, and a ground wire in one conduit and U2, V2, and W2, and a
ground wire in another; refer to NEC Article 300.20 and Article 310.4). National, regional, and industry
electrical codes should be referenced if three or more power conductors are run in the same conduit
(refer to 2008 NEC Article 310 adjustment factors).
Note: Local and national codes should be referenced when running more than three
conductors in the same conduit.
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 2008 NEC Article 430.
The ACE-tronics G9 ASD is designed and tested to comply with UL Standard 508C. Modifications to
the ASD system or failure to comply with the short circuit protection requirements outlined in this
manual may disqualify the UL rating. See
protection recommendations.
As a minimum, the installation of the ASD shall conform to 2008 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.
