Power And Ground Requirements
Check before turning the main power on!!
1. The standard voltage range is 208 to 240 VAC 3 phase. Voltage out of this
range could cause damage to the machine. Damage incurred through electrical
supply problems will not be warranteed.
2. Ensure that your electrical service is rated for proper current draw (Amps), and
that the appropriate wire size is used to feed the power. (See current/voltage
specifications on the serial data plate located on the door of the electrical
cabinet.)
3. Ensure that a copper wire equal to or greater in diameter than the power wires is
connected between our ground terminal and the main ground located at the
electrical service box. Also ensure that the electrical service box is tied to earth
ground.
4. Milltronics does not allow the use of a separate grounding rod.
5. Milltronics does not allow conduit or wire raceways be used as a ground.
6. If a transformer is used to step the voltage down to 220 refer to the transformer
grounding procedures immediately following this page. The secondary windings
of the transformer MUST be bonded to earth ground to avoid serious damage to
electrical components.
7. If there is a “wild leg” is must be connected to L2 on the main disconnect switch.
8. Failure to adhere to these requirements voids your warranty.
9. Milltronics does not accept responsibility for machine performance if the main
input power is not connected properly.
