SECTION II: ELECTRICAL HAZARDS (CONTINUED)
B. Servicing with “Power Off”
For maximum safety, unplug the service cord from the wall outlet before opening
the vendor door. This will remove power from the equipment and avoid electrical
and mechanical hazards. Service personnel should remain aware of possible
hazards from hot components even though electrical power is off. See the
appropriate sections of this manual for further information.
C. Servicing with “Power On”
Some service situations may require access with the power on. Power on servicing
should be performed
only by fully-qualified service technicians. Particular
caution is required in servicing assemblies that combine electrical power and
mechanical movement. Sudden movement (to escape mechanical action) can
result in contact with live circuits and vice versa. It is therefore doubly important to
maintain maximum clearances from both moving parts and live circuits when
servicing.
WARNING:
“POWER-ON” SERVICING SHOULD BE ACCOMPLISHED ONLY BY
FULLY-TRAINED PERSONNEL. SUCH SERVICE BY UNQUALIFIED
INDIVIDUALS CAN BE DANGEROUS.
Power to lighting and refrigeration system is shut off automatically by the electronic
controller when the outer door is opened.
Applies to V-Max only.
NOTE: For power-on servicing of the vendor’s lighting system, turn lighting power on by
accessing the “LIT” test function of the electronic controller (see programming
on inner door).
Applies to V-Max only.
For power-on servicing of the vendor’s refrigeration system, turn refrigeration
power on by accessing the “CNPR” test function of the electronic controller (see
programming on inner door).
Applies to V-Max only.
