DANGER!
Wiring Notes: PLEASE READ PRIOR TO INSTALLATION.
1. During installation, follow all local electrical, construction, and safety codes for
the country in which the AC drive is to be installed.
2. Make sure the appropriate protective devices (circuit breaker or fuses) are
connected between the power supply and AC drive.
3. Make sure that the leads are connected correctly and the AC drive is properly
grounded. (Ground resistance should not exceed 0.1 .)
4. Use ground leads that comply with AWG/MCM standards and keep them as
short as possible.
5. Do not use a power circuit contactor or disconnect switch for run/stop control
of the AC drive and motor. This will reduce the operating life cycle of the AC
drive. Cycling a power circuit switching device while the AC drive is in run
mode should be done only in emergency situations.
6. Multiple
DURA
PULSE
units can be installed in one location. All of the units
should be grounded directly to a common ground terminal. The
DURA
PULSE
ground terminals may also be connected in parallel, as shown in the figure
below. Make sure there are no ground loops.
7. When the AC drive output terminals T1, T2, and T3 are connected to the motor
terminals T1, T2, and T3, respectively, the motor will rotate counterclockwise
(as viewed from the shaft end of the motor) when a forward operation
command is received. To reverse the direction of motor rotation, switch the
connections of any of the two motor leads.

: Tighten all screws to the proper torque rating. See “Main Circuit Wiring”
later in this chapter.
W
ARNING
: Do not connect the AC input power to the T1, T2, and T3 output terminals.
Doing this will damage the AC drive

!
Before making any connection to the AC drive, disconnect
all power to the AC drive, and wait five minutes for DC bus capacitors to discharge.
