1 When bypassing the TB1/TB2 terminations, ensure that unshielded motor power conductors are kept as short as
possible at the drive, as they will radiate high levels of electrical noise.
Note: Refer to Figure 1.3 for the location of the TB1/TB2 connectors
and pin-out diagram.

IMPORTANT
The thermal circuit includes filtering on the TB1/TB2
connector board that is rated for 24V only. For TB1/
TB2 wiring alternatives, refer to the table below.
If: Then:
120V ac is used on the start/stop string
Option 1: Install a 24V pilot relay on the
thermal switch circuit.
Option 2: Bypass the TB1/TB2 terminations

.
24V is used on the start/stop string Follow the wiring shown in Figure A.9 above.

Implementation of safety circuits and risk assessment
is the responsibility of the machine builder. Please
reference international standards EN1050 and EN954
estimation and safety performance categories. For
