Power Connections and Precautions
WARNING 3 : Electrocution and Electrical Burn Hazards —Contact with electric power
can kill or seriously injure you. Electric power is present inside the cabinetry unless the main
machine power disconnect is off.
• Do not service the machine unless qualified and authorized. You must clearly understand
the hazards and how to avoid them.
Notice 4 : Machine Damage
—Voltage fluctuations of more than 10% above or below the
specified voltage for your machine can damage electrical components, especially motors.
• Any such conditions should be corrected prior to commissioning your machine.
1. Electrical connections must be made by a competent electrician.
2. Machine must be grounded by connecting to a grounded metal, permanent wiring system, or
an equipment-grounding conductor must be run with the circuit conductors and connected to
the equipment-grounding terminal on the machine.
3. Stinger leg, if any, must be connected to terminal L3, never to terminals L1 or L2.
4. Make power connections within junction boxes on the rear of the machine.
5. Verify motor rotation ( Figure 1 ). See the operating and trouble shooting manual for more
information. If the cylinder turns in the wrong direction, interchange the wires connected to
L1 and L2. Never move L3 under any circumstances. All motors are phased for proper
rotation. Never attempt to reconnect motors or the motor control devices.
6. Machines ordered for 208/240 volt operation are shipped set for 240 volt operation from the
factory ( Figure 2 ). If the supply voltage is 208 volts, then remove the top, and place the line
voltage switch in the 208 volt position.
