GENERAL
Vendo 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 qualified 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
Vendo 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 identified 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.
ALWAYS TEST TO VERIFY PROPER GROUNDING PRIOR TO
