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
19…24) 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 3.5
, Figure 3.6
and Figure 3.7
.
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 3.E
.
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 19…24 located
inside the Option Cabinet.
– Drive Start/Stop
– Drive/Bypass Enable
– Bypass Run
❏ 4. Tighten the I/O terminals to the proper torque according to drive type as
shown in Table 3.E
.
