Wire the Safe Torque-off Circuit

This section provides guidelines for wiring safe torque-off connections to the QSHT 5700
inverter.

Install the Safety Connector Plug

The safety connector plug (PN-445389, TBPLUG, LOCKING, 180 Deg, RED, AU) has two
locking levers that are pushed in a clockwise direction as the plug is inserted into the QSHT
5700 inverter connector. This is the locked position. Rotate the levers counter-clockwise to the
open position to release the connector plug.
IMPORTANT Push the locking levers clockwise into the locked position

use an external 24V supply for the external safety device that
triggers the safe torque-off request. To avoid jeopardizing
system performance, do not use pin ST0-1 as a power supply
for the external safety device.
