Drive Setup and Adjustment
3.1 Perform a Power Off Inspection
Inspect the drive and modification kits for possible physical damage or improper
connections.
Verify that the wiring of the operator's station and the wiring to the drive is made with
sufficient bare wire to make a good electrical connection. The removal of an excessive
length of insulation may needlessly expose conductors, resulting in the possibility of
shorts or safety hazards.
3.2 Verify Control Transformer Tap Settings
Before input power is applied to the drive, verify that the control transformer taps are
set to match the input power. Note that most FlexPak 3000 drives ship from the factory
configured for 460 VAC input power (or 415 VAC for current-rated drives). These
factory settings can be changed to configure the drive for 230 VAC or 380 VAC input
power. The conversion procedures are described in sections 3.2.1 and 3.2.2.
3.2.1 Converting a Drive for 380 VAC Input Power
380/415 VAC-rated drives are shipped from the factory configured for 415 VAC line
input. Wire 782 is connected to terminal H1 and wire 783 is connected to terminal H3.
To configure the drive for 380 VAC operation, perform the following steps:
Step 1. Disconnect and lock out all incoming power to the drive.
Step 2. Move wire 783 to terminal H2. See figures 3.1 and 3.2 for terminal locations.
Step 3. Through the OIM, perform the Nominal AC Line Volts Adjust procedure as
described in section 3.9.

ATTENTION: 380/415 VAC-rated FlexPak 3000 drives can be configured
for either 380 VAC or 415 VAC input power. Before input power is applied
to the drive, verify that the control transformer taps are set to match the
input power. Failure to observe this precaution could result in damage
to, or destruction of, the equipment.
