Electrical Requirements
Grounding Instructions
NOTE: To ensure protection against shock, this
tumbler MUST be electrically grounded in
accordance with the local codes or, in the absence of
local codes, with the latest edition of the National
Electrical Code ANSI/NFPA No. 70. In Canada the
electrical connections are to be made in accordance
with CSA C22.1 latest edition Canadian Electrical
Code, Part I, and/or local codes.
This tumbler must be grounded. In the event of
malfunction or breakdown, grounding will reduce the
risk of electric shock by providing a path of least
resistance for electric current. This tumbler must be
connected to a grounded metal, permanent wiring
system; or an equipment grounding conductor must be
run with the circuit conductors and connected to the
appropriate ground location.
● Metal conduit and/or BX cable is not considered
ground.
● Connecting the Neutral from the electrical
service box to the tumbler ground screw does not
constitute a ground.
● A dedicated ground conduit (wire) must be
connected between the electrical service box
ground bar and the tumbler ground screw.
For CE Models Only
All manually operated models are factory-equipped
with an emergency stop button on the front panel. If
the emergency stop function is desired on coin-
operated models, an external emergency stop button
may be installed as specified on the machine wiring
diagram.
NOTE: Activation of the emergency stop button
stops all machine control circuit functions, but
DOES NOT remove all electrical power from
machine.
WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the tumbler
before servicing.
• Close gas shut-off valve to gas tumbler
before servicing.
• Close steam valve to steam tumbler
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the
tumbler is properly grounded.
W002
To reduce the risk of fire and electric
shock, check with a qualified serviceman
for proper grounding procedures. Improper
connection of the equipment grounding
conductor may result in a risk of electric
shock.
W068
To reduce the risk of fire and electric
shock, if electrical supply is coming from a
three phase service, DO NOT connect a
“High Leg” or “Stinger Leg” to a single
phase machine. On a three phase machine,
if there is a “High Leg” or “Stinger Leg” it
should be connected to L3.
W069
All electrical connections should be made
by a qualified electrician.
To reduce the risk of electrical shock, de-
energize the electrical circuit being
connected to the tumbler before making
any electrical connections. Never attempt
to connect a live circuit.
W070
WARNING
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation. Verify
proper operation after servicing.
