power to the main housing unit , a
hole for the cable from the power
source should have been drilled at
the bottom of the control box, and
the cable should have been routed
through that hole. Verify steps 2 and
3 of procedure 2.1.2 have been
completed, and perform these steps if
they have not.
3. Connect the cable from the main
power source to the L1, L2, and L3
power distribution blocks.
4. Enable the power coming from the
main power source.
2.2.2 Verifying the blower fan rotation

facing the inlet grill side of the switch heater.
WARNING:
!
The main circuit breaker feed to
the electrical connections in the
main housing unit must be locked
out and/or tagged out to protect
employees against accidental or
inadvertent operation during any
servicing or maintenance activity.
Lockout is the best and preferred
method of isolating machines or
equipment from energy sources
prior to servicing any component
within the main housing unit. The
lockout/tagout procedure must
comply with employee safety rules
as defined by local corporate
regulation.
