SECTION II: ELECTRICAL HAZARDS
GENERAL
SandenVendo America, Inc. vending machines are provided with the appropriate power
supply setting for your area. Some models are equipped with step-down transformers, as
required. This enables the vending machine to operate on different main voltages. Refer
to Section I. E. for information to determine the main power requirements. Refer to the
appropriate service manual for details of step-down transformer operations.
The power sources just mentioned are standard for both household and commercial
lighting and appliances. However, careless or improper handling of electrical circuits
can result in injury or death. Anyone installing, repairing, loading, opening, or otherwise
servicing a vending machine should be alerted to this point. Apply all of the normal
precautions observed in handling electrical circuits, such as:
• Refrigeration servicing to be performed by qualifi ed personnel only.
• Unplug the vendor or move power switch to off position before servicing or clearing
product jams.
• Replace electrical cords if there is any evidence of fraying or other damage.
• Keep all protective covers and ground wires in place.
• Plug equipment into outlets that are properly grounded and polarized (where
applicable), and protected with fuses or circuit breakers.
• All electrical connections must be dry and free of moisture before applying power.
A
. Grounding Systems
SandenVendo America, Inc. vending machines are provided with the appropriate
service cord for the power supply in your area. The service cord will connect to
the matching electrical outlet. Always ensure that the outlet to be used is properly
grounded before plugging in the vendor. (See pages S-3 through S-5.)
The electrical grounding system also includes the bonding of all metal components
within the vendor. This involves a system of bonding wires identifi ed by green or green
and yellow marking. The system uses serrated head screws, lock washers, and star
washers to ensure the electrical connection between parts. Maintenance of vending
equipment may involve disassembly. Include the above items when reassembling, even
if the vending machine may appear to function normally without them. Omitting any
of these items can compromise a link in the grounding system. See the appropriate
service manual or kit instructions for components and assembly instructions.
WARNING:
ALWAYS TEST TO VERIFY PROPER GROUNDING PRIOR TO
INSTALLATION TO REDUCE THE RISK OF ELECTRICAL
SHOCK AND FIRE
