Control and Signal Wiring
Refer to the PowerFlex 400 User Manual for additional detailed information
about control and signal wiring.
The Signal Terminal Block (TB1 Terminals 1…20 and R1…R6) located on the
drive Main Control Board and Control Terminal Block (TB1 Terminals 31…40)
located inside the Option Cabinet provide terminals for interfacing customer
supplied control inputs and outputs. All analog and discrete control wiring will
be made at these terminals. Typical customer control and signal wiring is shown
on the Interconnect drawings,
Figure 84 on page 115 and Figure 87 on page 118 .
To connect control and signal wiring to the drive package:
❏ 1. Wire the control and signal leads by routing them according to the drive
option type. Note that you must punch openings in the option cabinet of
the desired conduit size, following NEC and all applicable local codes and
standards. Control and signal terminal block specifications are listed in
Table 9 .
Control and signal wires should be separated from power wires by at least
0.3 meters (1 foot).
❏ 2. Connect the analog and relay output signal wiring to terminals 1…20 and
R1…R6 located on the drive Main Control Board.
❏ 3. Connect the control wiring listed below to terminals 31…40 located inside
the Option Cabinet.
