Loose screws
2. Check that the wiring does not move at the screw terminal.
2 Take extra care not to ruin the screw thread due to fastening the screw at an angle.
* To prevent fastening the screw at an angle, install the round terminals so they are back to back.
3 After fastening the screw, use a permanent marker to tick off the screw head, washer and terminal.

<3> Installing the conduit tube
• Punch out the knockout hole for wire routing at the bottom of the front
panel with a hammer.
• When putting wires through knockout holes without protecting them
with a conduit tube, deburr the holes and protect the wires with
protective tape.
• If damage from animals is a concern, use a conduit tube to narrow the
opening.
• Always use a conduit to run the power supply wiring.
• Select the conduit size based on the knockout hole.
