1. At least 4” thick concrete slab free of cracks and not crossing any expansion joints. Milltronics will not guarantee machine geometry unless this is adhered to. 2. Ample ceiling height, and clearance behind the machine to fully open the door of the electrical cabinet at the rear of the machine. -
Page 24: Power And Ground Requirements
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. -
Page 25: Connecting A Transformer
3 – S HAPTER REPARATION Connecting a Transformer It is important that proper grounding procedures be followed when hooking up machines to power. Please review the following pages. They explain proper transformer connections and checks to ensure proper connections. Refer to the autotransformer diagram provided to verify that your connections are suitable. -
