ASD−TB1−ACI
Installation Procedure
The Terminal Block w/120VAC input PCB
assembly provides the user with the capability to
use 120VAC control for the discrete inputs to the
motor drive. This PCB assembly accepts
120VAC ON/OFF control logic and transforms
it into an open collector output. This is
accomplished by using voltage threshold
detection optocoupler HCPL-3760. The
optocoupler has several useful features:
hysteresis for extra noise immunity, a diode
bridge for use with AC inputs and internal
clamping circuits to protect against over-voltage
and over-current transients.
Installation
This procedure should be performed by properly
trained personnel only. Lock and tagout all
applicable power sources. Ensure that power has
been removed from the ASD and that the Power
and Charge LEDs are off.
The terminal block PCB assembly comprises the
following parts:
i) 52300: Terminal block PCB (Qty. 1)
ii) 52105: 120VAC input isolator PCB
(Qty. 2)
iii) 50611: 4-20mA Jumper PCB (Qty. 1)
iv) 48576: 4-20mA signal isolation PCB
(Optional: Can be used instead of 50611
for isolation of 4-20mA input and
FM/AM outputs. Please contact
Toshiba for details.)
Remove the existing terminal block board
(48570) and the jumper board (50611).
Remove the jumper PCB (50611) from the ASD-
TB1-ACI assembly. Install the assembly using
the same mounting holes as the previous
terminal block board. Replace the jumper PCB
(50611).
The discrete inputs that will accept 120V AC
voltage are F, R, RES, ST, S1, S2, S3 and S4.
The common neutral for all the above inputs will
be connected at terminals 9 and/or 17 on TB1.
DO NOT use the CC terminals 1 & 2 on TB1 for
connecting the 120VAC signals. Note that the
CC terminals are used only for the analog control
inputs.
The Nomex tape between the isolator PCBs
(52105) is provided for voltage clearance. DO
NOT remove this tape.
For wiring and layout of the electrical
connections external to the ASD, adhere to all
applicable codes and standards. The control
cabling should not be run with the power cables
in the same conduit. Shielded cables are
recommended for control cabling. Proper
grounding methods shall be employed.
No programming changes are required
specifically because of using this board.

and parameters, see the G7 Adjustable Speed
Drive Operation Manual (P/N 51546).
