Interconnect Diagrams A-13
The example below shows 1394 (Series A and B) axis modules wired
for thermal fault monitoring. Depending on how the 1394 system is
configured, the fault can be used to disable one or all of the four axis
modules. Two separate 24V dc power supplies and four relays (CR2-
CR5) are included to isolate the thermal inputs from conducted noise.

Isolated with Thermal Fault Monitoring
1 120V ac (50/60 Hz) power may be used in place of 24V dc for motor thermal switch circuits in Series A and B axis
modules.
Note: Refer to Figure 1.3 for the location of the TB1/TB2 connectors
and pin-out diagram.
