Grounding Instructions
Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded while in use to protect the operator from electric shock and possible fatal injury.
Before connecting power, make sure the electrical current of your power source matches the electrical system on the shaper.
To connect power, proceed as follows:
1.Remove two screws (A, Figure 14) and remove terminal strip cover (B, Figure 14).
2.Remove clear plastic insulator (C, Figure 15) that covers the terminals.
3.Insert power line through opening (D, Figure 14) of terminal strip box.
4.Connect the three power lines to terminals L1, L2 and L3, as shown (E, Figure 16). Also connect the green ground wire to terminal (F, Figure 16).
5.Reassemble the clear plastic insulator (C, Figure 15) and the terminal strip cover (B, Figure 14).
Make sure incoming power matches voltage on motor plate.
6.The shaper is prewired 230V. If you will be connecting to 460V power, you must first:
•Connect the inbound line on the transformer from the 230V to the 460V post, and wire motor to 460V.
•Set overload relay to lowest setting.
The same controls will be used as for 230V.
7.Turn the machine on and make sure the direction of the shaft rotation is correct. Looking down on the top of the spindle, the spindle should be turning counterclockwise as shown in Figure 17. If it is not, reverse any two incoming power leads.
8.When wiring is completed, tape all power box joints to keep out dust.
After connecting this machine to the power source, the terminal box is still electrified even while the power switch is shut off. Open the terminal box only when power has been disconnected
