Installation/Wiring 2–39
Auxiliary Inputs - TB4, TB6 Terminal blocks TB4 and TB6 (B Frame drives & up) allow the drive
power supplies to be operated from an external voltage source. Both
terminal blocks are located on the Base Driver Board and are accessi-
ble from the front of the drive. See
Figure 2.1 for locations.
TB4 can be used to externally power the low voltage power supply,
allowing operation of drive control functions in the absence of bus
voltage. Applying proper voltage to TB4 (see
Table 2.J ) provides
+5V,
±15V and isolated 12V outputs for:
• Main Control Board (Control Interface Boards, RIO Board, etc.)
• SCANport™ (HIM, etc.)
• Encoder(s)
• LEMS
• Precharge
• Any DC fans in the drive
TB6 can be used to externally power the high voltage power supply
which provides inverter IGBT drive voltage and the low voltage nec-
essary to power the low voltage power supply. This allows operation
of the drive in the absence of bus voltage.
The maximum and minimum wire size accepted by TB4 is 2.1 and
0.06 mm
2 (14 and 30 AWG). Wire sizes for TB6 are 5.3 and 0.06
mm 2 (10 and 30 AWG). Use Copper wire Only with a minimum tem-
perature rating of 75 degrees C. Do not reduce wire gauge when using
higher temperature wire. Maximum torque for both terminal blocks is
0.57 N-m (5 lb.-in.).

Power Supply Input Requirements
1
1 The power source used to drive a power supply must be capable of providing the peak current at startup.
A “flat“ current or power limit is acceptable, but a foldback current limit may trip at startup, never allowing
the supply to start.
2 Must be supplied from a Class 2 Limited Power Source.
3 Must be supplied from a source that is provided with transient voltage surge suppression such that
transients are suppressed to 6000V peak maximum or less.
