• When you tighten slotted screws, hold the straight-edge screwdriver perpendicularly to the screw. Make sure that
you align the end of the straight-edge screwdriver with the screw groove.
• 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 7.5 for an example.
