Control Terminal
Block – 8…9 Provides contact for field wired hardware enable circuit (See page 295 for more detail) and
contactor control if ordered without the X1 option. Frame 8 drives with cabinet options ship
with a hardware enable jumper on TB4. This may be removed and replaced with field wiring
for hardware enable.
Thermostat – 8…9 Monitors cabinet options bay for temperature and wired to drive hardware enable input. Will
disable system when over temperature is detected in order to protect cabinet option
components. Note: A ventilation fan failure in the cabinet options bay will not disable the
drive unless an over temperature is detected by the thermostat.
