6.7.3 540, 850, 1550, and 3000 ADC
Use the following information to wire units rated at 540, 850, 1550, and 3000 ADC in
accordance with the National Electrical Code. Always review local building and
electrical codes before making electrical connections to this device. Refer to Table 6-3
for recommended wire sizes.
System interconnections such as digital and analog inputs and outputs, tach, serial link,
etc., are made to the quick connect type terminal blocks on the left side of the drive. No
lugs are required for these connections. These terminals accept #22 to #16 AWG wire.
Strip insulation 0.27" from the end of the wire.
Auxiliary field excitation transformer, emergency stop, E-stop reset, M-contactor coil and
aux contacts, armature bridge blower, and aux control power transformer connections are
made to the rail-mounted terminal block (TB1) on top of the field supply and (TB2) on
the bottom. No lugs are required for these connections. These terminals accept #22 to
#14 AWG wire. Strip insulation 0.39" from the end of the wire.
6.7.4 CONTROL POWER TRANSFORMER CONFIGURATION
10-510 ADC Drives
The control transformer (T1) is located near the bottom of the base assembly. Refer to
Figure 6-1. Set the jumpers on T1 for the correct incoming AC line voltage (230 or
460 VAC).
550 ADC Drive
The control transformer (T1) is located near the right-center of the base assembly. This
model may be configured for 230, 460, or 575 VAC input. Transformer terminals H2,
H3, and H4 are used to set the transformer’s input voltage. Refer to Figure 6-3 (Block
Diagram, Power Connections, 550 ADC) or the drive schematic D26053 for
configuration connection points. If the unit is to be operated at 230 VAC, remove the
input wire from terminal H3 and connect it to terminal H2. For 575 VAC, remove the
input wire from terminal H3 and connect it to terminal H4. See step 7 of paragraph 7.7
for required fuse change information.
540, 850, 1550 and 3000 ADC Drives
The control transformer is mounted external to the drive.
