Electrical Requirements

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

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 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.

Installation/Operation Supplement

●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.

WARNING

To reduce the risk of electrical shock, de-energize the electrical circuit being connected to the tumbler before making any electrical connections. All electrical connections should be made by a qualified electrician. Never attempt to connect a live circuit.

W409

CAUTION

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

W071

All OPL (non-vend) models are factory-equipped with an emergency stop button on the front panel.

NOTE: Activation of the emergency stop button stops all machine control circuit functions, but DOES NOT remove all electrical power from machine.

NOTE: This manual is only a supplement. Refer to installation/operation manual for full instructions.
