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 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
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 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.
WARNING:
ALWAYS TEST TO VERIFY PROPER GROUNDING PRIOR
TO INSTALLATION TO REDUCE THE RISK OF ELECTRICAL
