Figure 3.22 Tightening Slotted Screws
• After you connect the wires to the terminal block, lightly pull on the wires to make sure that they do not come
out of the terminals.
• Remove the correct section of the wiring cover to make wiring easier.
• Do not let strain on the wiring cause damage. Use a strain relief near the wiring to release the tension. Refer to
Figure 3.23 for an example.
