– 8 and 9 Provides contact for field wired hardware enable circuit (see
page 307
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 jumper can be removed and
replaced with field wiring for hardware enable.
Thermostat – 8 and 9 Monitors cabinet options bay for temperature and wired to drive
hardware enable input. Disables the system when over temperature
is detected to help protect cabinet option components.
IMPORTANT: A ventilation fan failure in the cabinet options bay does
disable the drive unless an over temperature is detected by the
thermostat.
